[0014] Abbreviation

[0015] The invention relates to a carrier for storing natural intestines, comprising:

[0016] - a tube with a jacket for receiving natural casing along a longitudinal axis X of the tube; wherein the tube has a first end region at a first tube end and a second end region at a second tube end; - at least a second retention means at the second end region of the tube for preventing the natural casing from slipping off the jacket; wherein the second retention means is a second strip retention means and comprises:

[0017] - at least one second strip extending along the longitudinal axis X in the direction of +X as a continuation of the mantle;

[0018] - at least one second stripe image that has an opening on the mantle on the opposite side of the second stripe;

[0019] The carrier can be attached to a mandrel for winding the natural casing in the direction of +X.

[0020] At least one second gap extending between the second strip recording and the second pipe end is assigned to the pipe in the second end area.

[0021] The second strip can be bent in such a way and guided through the second slit to the second strip recess, so that the second strip is captured in the second strip recess and partially protrudes from the mantle away from the longitudinal axis X.

[0022] According to one variant, the carrier comprises a second strip restraint device and a pipe, which are formed in one piece.

[0023] The advantage is that the second strip retention material in a sausage factory cannot fall into the sausage meat.

[0024] According to another variant, the support includes a second pipe end along the longitudinal axis X, which is spaced away from a second strip mounting by more than a pipe outer radius.

[0025] The advantage is that a second natural intestine overhang in the second end area of ​​the natural intestine already mounted on the casing of the tube cannot hang beyond the end of the tube.

[0026] According to a special variant, the carrier includes a second strip which has second strip incisions into which the second strip receptacle can penetrate.

[0027] The advantage is that the second strip is thus fixed in place. This contributes to a safer and better slip resistance.

[0028] According to an alternative design, the support in the second end area includes a second gap between the second strip holder and the second pipe end, allowing the strip to pass through. This gap is designed as a slot. The advantage is that the slot prevents the strip from being unintentionally retracted and contributes to the stability of the anti-slip device.

[0029] According to one variant, the carrier in the second end area includes a second strip recess, which is designed as a slot partially aligned radially with the tube.

[0030] The advantage is that the second strip holder, acting as a slot, holds the strip in place and thus contributes to the stability of the anti-slip device.

[0031] According to another variant, the carrier includes a second strip, the strip length of which is wider than the caliber of the natural intestine. This strip length is the longest dimension of the strip and is referred to here as a predetermined width.

[0032] The advantage is that the greater width of the strip prevents the natural intestine, which is already mounted on the casing of the tube, from slipping out.

[0033] In another variant, the support at the first end of the tube includes a first retention element, which is a first strip retention element. This first strip retention element has the properties of the second strip retention element and prevents the natural casing, already mounted on the tube's outer layer, from slipping out.

[0034] The advantage is that the first strip restraint acts as a stable anti-slip barrier.

[0035] According to a preferred variant, a first retention device, a second retention device and the pipe are formed in one piece.

[0036] The advantage is that with a one-piece carrier, no retaining agent can fall into the sausage meat. One-piece means that the retaining agents are integrated into the tube.

[0037] According to a special variant, the carrier comprises a pipe, a second strip restraint device and a first restraint device, which is any first restraint device from the prior art.

[0038] Table 1 shows the diameter of the tube in relation to the caliber of the natural casing to be placed on it. Such a tube typically has a length of 500 mm and a wall thickness of approximately 0.5 mm. A natural casing with a caliber of 20 / 22 is usually placed loosely and with a sliding motion on a tube with a diameter of 15.2 mm. This means that the natural casing exerts no force on the tube because the circumference of the 15.2 mm diameter tube is designed to accommodate the 20 / 22 mm natural casing without any force being applied.

[0039] Table 1: Outer diameter of tube vs. caliber of natural casing

[0040] The retaining device according to the invention in the second end region of the tube is designed as an integrated component of the tube and has a width that is larger than the caliber of the natural intestine to be received, so that the natural intestine already received on the tube is prevented from slipping out.

[0041] The pipe and the retaining means may comprise or be made of elastic or plastic material.

[0042] Elastic means: flexible, supple, yielding, and springy. For example, an object made of an elastic material can, after being deformed from a first position to a second position, return to its first position, or spring back or snap back, without plastic deformation occurring.

[0043] Elastic plastics have a deformation modulus of approximately 10 4 N / mm 2 .

[0044] An example of an elastic plastic is PE-HD, polyethylene (HD = high density), with a modulus of elasticity of 1200 N / mm². 2 .

[0045] Plastic means flexible, pliable, yielding, and exhibiting a permanent deformation after deformation. For example, an object made of a plastic material cannot return exactly to its original position after being deformed from one position to another. The return to its original shape may only be partial.

[0046] Plastic polymers have a deformation modulus of < 10' 1 N / mm.

[0047] An example of a plastic is TPU-85, thermoplastic polyurethane elastomer, with a modulus of elasticity of 600 N / mm². 2The support structure for all variants and designs comprises a material made from fossil-based or bio-based plastics, such as PE, PU, ​​or PLA. To design the support structure with an improved carbon footprint, the pipe and retaining element can incorporate a biodegradable plastic, which may be home-compostable and / or industrially compostable. Examples of such plastics are PLA and PBS. The support structure can also be made from a bio-based plastic, such as PLA.

[0048] According to current technology, tubes are used for preparing natural casings. These tubes are also called hard tubes. For preparing the natural casing onto such a tube, a mandrel is used, onto which the tube is then attached.

[0095] Detailed description

[0096] Fig. 1 shows a schematic view of a carrier 100 for storing natural casings. The carrier 100 has a tube 120 with a jacket 130. The tube 120 comprises a first end section 121 at a first end and a second end section 122 at a second end.

[0097] Fig. 2 shows a first embodiment of the invention. The support 100 comprises at least one first retaining means at the first end region 121 of the tube 120 to prevent the natural casing 900 from slipping off the sheath 130. The support 100 can additionally or alternatively comprise a second retaining means at the second end region 122 of the tube 120 to prevent the natural casing 900 from slipping off the sheath 130.

[0098] For assembly, the carrier 100 is usually placed on a dome to pull the natural casing 900 in a direction +X onto the outer shell 130 of the carrier 100. The object of the invention is to provide a carrier for storing natural casings in which the retaining agent cannot fall into the sausage meat.

[0099] The solution to the problem according to the first embodiment of the invention is that the second retention means of the carrier 100 is a second strip retention means 152. The first embodiment with several variants relates to the strip retention means.

[0100] Fig. 2 shows a top view of the support 100 with the first end region 121 and with the second end region 122 of the tube 120.

[0101] Fig. 2 shows at the second end region 122 the second strip retention means 152, which has a second strip 153 that is connected to the sheath 130 at a second connection point 151.

[0102] A directional arrow along a longitudinal axis X indicates the direction of pulling the natural intestine 900 onto the first end region 121 and pulling the natural intestine 900 off at the second end region 122 of the tube 120. Fig. 2 is a top view and shows the second strip retention element 152 in a first position of the second strip 153, which extends along the longitudinal axis X in the direction +X.

[0103] Fig. 3 is a bottom view of the carrier 100 and shows the second strip retention element 152 in a first position of the second strip 153. A detail of the second end region 122 is indicated by the letter "C". Fig. 5d shows the detail "C" at the second end region 122. The carrier 100 has a second slot 154 at the second end region 122 on the opposite side of the second strip 153, which is connected to a second strip receptacle 155. In one embodiment, the second slot 154 is designed as an elongated groove along the longitudinal axis X. The second strip receptacle 155 is an opening on the surface 130, which is designed, for example, as a groove transverse to the longitudinal axis X. Fig. 5d shows that the second slot 154 and the second strip receptacle 155 are connected to each other as a T-slot.Figure 3 shows that the second gap 154 ​​extends from the second strip recording 155 to a second tube end 156 in the second end area 122.

[0104] Fig. 3 shows a T-slot at the first end region 121, which differs from the T-slot at the second end region 122. The first receptacle 145 of the first end region 121 is rectangular in Figs. 3 and 6a, and the second receptacle 155 at the second end region 122 is triangular (Figs. 3 and 6). The triangular receptacle acts like a slot and provides a stable position for the connection between the second strip 153 and the receptacle 155 in the second position of the second strip 153. That is, when the second strip 153 is in the bent state, it has a stable position. The first receptacle 145 can also be triangular.

[0105] The second gap 154 ​​can be configured as a slotted gap instead of an elongated groove. The second strip receptacle 155 can be configured as a slotted transverse gap instead of a groove. These slots contribute to the robustness of the second strip receptacle 152 due to improved connection. A second reinforcing element 159 can further contribute to the robustness of the second strip receptacle 152. The second reinforcing element 159 can, for example, be at least one fold or at least one groove on the second strip 153, which increases the bending stiffness of the second strip 153.

[0106] Everything that applies to the second strip retention device 152 also applies to the first strip retention device 142. Only the orientation directions differ, namely direction -X and direction +X.

[0107] In a process, the second strip 153 is bent from a first position around the second connection point 151 by approximately 90° to a second position and is guided through the second gap 154 ​​until it then enters the second strip receptacle 155.

[0108] In a first position, the second strip 153 runs parallel to the longitudinal axis X (Fig. 4). In a second position, the second strip 153 is at a 90° angle to the first position (Fig. 5).

[0109] Fig. 5d shows how the second strip 153 is surrounded and held by the second stripe receiver 155.

[0110] Fig. 4 is a side view of Fig. 2. A detail of the first end region 121 is indicated by the letter “A”. Fig. 5a shows detail “A” at the first end region 121. The carrier 100 has a first gap 144 at the first end region 121 on the opposite side of the first strip 143, which is connected to a first strip receptacle 145 (Fig. 5e). See the description for detail “C” and Fig. 5d.

[0111] As a supplement to detailing “A”, Fig. 5b shows detailing “A’”, that the first strip 143 has bent around the first connection point 141 by 90° and is received in the first strip holder 145, where it is held.

[0112] In a first position, the first strip 143 runs parallel to the longitudinal axis X (Fig. 5a). In a second position, the second strip 143 is at a 90° angle to the first position (Figs. 5b, 5bl). Fig. 5 shows a schematic side view of the carrier 100 with a natural casing 900 already mounted on it. The first strip 143 is in the second position and acts as a stop, preventing the natural casing 900 from slipping out on the opposite side. However, the natural casing 900 can move a limited length 901 in the direction of -X at this point and be held there stably. The length 901 is the length of the first natural casing overhang in the first end region 121.

[0113] Therefore, it is important that a first gap 148 be provided as a reserve between the first strip holder 145 and the first tube end 146, so that the natural casing 900 cannot slip beyond the first tube end 146 (Fig. 6a). The first gap 148 can be on the order of the tube's outer radius Ra. The first gap can preferably be between 0.25R a and 2R a or even more preferably, IRa.

[0114] Fig. 5bl shows that in a further embodiment of the invention the first strip 143 can comprise a first loop 143L.

[0115] Fig. 5bl shows that the first strip 143, starting from the initial position, first bent approximately 90° away from the longitudinal axis X and then turned approximately 180° towards the longitudinal axis X, forming a first loop 143L. The first strip 143 can then be guided through the first gap 144 to the first strip holder 145. Thus, the first strip 143 is captured in the first strip holder 145 and protrudes partially from the sleeve 130 away from the longitudinal axis X. The first strip 143 is now in the second position (Figs. 5cl, 5e).

[0116] The advantage of the embodiment of Fig. 5cl over the embodiment of Fig. 5c is that the width B rmore effectively, i.e., on both sides, can be achieved. The length 901 of the first natural gut overhang in the first end region 121 is significantly shortened. The first strip 143 with the first loop 143L can act much more stably in the second position, i.e., the position as a sliding obstacle (Fig. 5). Fig. 5c shows a front view of the carrier 100. Here it can be seen that the first strip 143 is bent by approximately 90°. An angle of 90° ± 70° is a good choice. Preferably 90°+50° for the first strip 143 and 90°-50° for the second strip 153. As an example, in Fig. 5 the first strip 143 is bent by 90°-50° and the second strip 153 by 90°+50°.

[0117] Fig. 5c shows a front view of the carrier 100 with the bent first strip 143 having a strip length B r, which is the longest dimension of the strip and is referred to here as a predetermined width wider than the caliber of the natural intestine (see Table 1). One end of the first strip 143 is wider to allow for better retention.

[0118] Fig. 5cl shows a front view of the carrier 100 as in Fig. 5c but with a first loop 143L on the first strip 143.

[0119] Fig. 5h shows a schematic view of a second strip 153 of the carrier 100. The second strip 153 can include at least one second strip notch 157, into which, as shown in Fig. 5f, the second strip receptacle 155 penetrates, thus fixing the second strip 153 more securely. The second strip notch 157 can be slot-shaped.

[0120] Fig. 5i shows a schematic view of a first strip 143 of the support 100. The first strip 143 can include an area for the first loop 143L. It is understood that in Fig. 5i, the area labeled (— ► 143L) is not yet a loop. As described for Fig. 5bl, the first loop 143L is formed. The first strip 143 can vary along its length. Fig. 5i shows a first shape 143F on the first strip 143, which is intended to indicate the variations in shaping along the first strip 143. In Figs. 5i and 5cl, a hexagon is shown for the first shape 143F. The first shape 143F can have any other geometric shape, such as a circle, rectangle, ellipse, or triangle. The purpose of the first shape 143F is to hold the first strip 143 stably within the tube. The first stripe recording 145 has already been described in detail using Figs. 5a, 5b, 5bl, 5e, 5g, 6a. At least one first loop recording 149 (Fig.5bl) are provided on the opposite side of the first strip holder 145 so that the first strip 143 is caught there and the first loop 143L is stably stored between the first loop holder 149 and the first strip holder 145. The first shape 143F prevents the first strip 143 from slipping through one of the strip holders. All descriptions for the second strip holder 152, as shown in Figs. 5d, 5f and 5h, are also valid analogously for the first strip holder 142. All descriptions for the first strip holder 142, the first strip holder 145 and the first loop holder 149, as shown in Figs. 5a, 5b, 5bl, 5c, 5cl, 5e, 5g, 5i and 6a, are also valid analogously for the second strip holder 152.

[0121] The only difference between the first strip retention device 142 and the second strip retention device 152 is that the first strip retention device 142 is arranged at the first end area 121 where the natural casing 900 is pulled onto the carrier 100 and that the second strip retention device 152 is arranged at the second end area 122 where the natural casing 900 is pulled off the carrier.

[0122] To pull the natural intestine 900 onto the carrier 100, the natural intestine is pulled over the first strip retention medium 142 or the first strip 143, so that the first strip 143 is pulled along by the natural intestine 900.

[0123] For assembly purposes, the carrier 100 is placed on a mandrel (not shown) which, according to the prior art, has a clamping device. The first strip 143 (see Figs. 2, 3, 4 and 5a) is manually secured by means of the mandrel's clamping device. Thus, the first strip 143 does not obstruct the process, allowing the natural casing 900 to be pulled onto the sheath 130 in the +X direction without obstruction (see Fig. 5). The carrier 100 can then be removed from the mandrel in the -X direction. The first strip 143 is then moved from the first position to the second position (see Figs. 5, 5a, 5b), so that the first strip retaining element 142 prevents the natural casing 900, already pulled onto the sheath 130, from slipping off. The second strip 153 (see Figs. 2, 3, 4) is also moved from the first position (see Fig. 4) to the second position (see Fig. 5).5, 5c) rearranged so that the second strip retention means 152 prevents the natural casing 900 already mounted on the jacket 130 from slipping off (see Fig. 5).

[0124] Fig. 6 is a detailed representation of the second end region 122 of the support 100 of Fig. 3.

[0125] Fig. 6a is a detailed view of the underside of the first end region 121 of the support 100 of Fig. 3.

[0126] The second strip retention element 152 can be angular or rounded at its distal end, i.e., away from the second connection point 151 of the second strip 153. The rounded second strip 153 is gentler on the natural intestine 900 and prevents injury to the natural intestine 900. Figures 2, 3, 4, and 5 show that the first retention element 142, the second retention element 122, and the tube 120 are formed in one piece as a single unit. The retention elements are formed at their ends by cutting processes such as punching.

[0127] In a process I for mounting the natural casing 900 onto the tube 120, the following steps are carried out:

[0128] - Provision of the natural intestine 900;

[0129] - Provision of the support 100; wherein the support comprises a tube 120 with a first end region 121 and a second end region 122, wherein the support 100 has a first strip restraint 142 with a first strip 143 at the first end region 121, wherein the support 100 has a second strip restraint 152 with a second strip 153 at the second end region 122,

[0130] - Attaching the carrier 100 to a clamping dome;

[0131] - Clamping the first strip 143 in a clamping device of the clamping dome;

[0132] - Pulling the natural intestine 900 onto the tube 120 at the first end area 121 of the tube 120 over the first strip retention element 142;

[0133] - Unplugging the carrier 100 from the clamping dome;

[0134] - Changing the first strip 143 from an open first position to a closed second position;

[0135] - Changing the second strip 153 from an open first position to a closed second position.

[0136] In a process II for removing the natural casing 900 from the tube 120, which was mounted according to process I, the following steps are carried out:

[0137] - Changing the second strip 153 from a closed second position to an open first position; or

[0138] - Attaching the carrier 100 from the side of the second end region 122 onto a sausage tube, whereby the second strip 153 is positioned on the inside of the sheath 130 of the tube 120 along the longitudinal axis in the direction -X without the need to reposition the second strip 153 from the second position to the first position;

[0139] - The natural casing 900 is pulled off the tube 120 at the second end region 122 of the tube 120 via the second retaining strip 152. Fig. 7 shows a second embodiment of the invention. The support 100 comprises at least one first retaining strip at the first end region 121 of the tube 120 to prevent the natural casing 900 from slipping off the sheath 130. The support 100 can additionally or alternatively comprise a second retaining strip at the second end region 122 of the tube 120 to prevent the natural casing 900 from slipping off the sheath 130.

[0140] For assembly, the carrier 100 is placed on a dome in order to pull the natural casing 900 in one direction +X onto the jacket 130 of the carrier 100.

[0141] The object of the invention is to provide a carrier for storing natural casings in which the retaining agent cannot fall into the sausage meat.

[0142] The solution to the problem according to the second embodiment of the invention is, as shown in Figs. 7, 8 and 8a, that the second retaining means of the support 100 is a second arc retaining means 250 and comprises a second arc 251 which is curved outwards from the shell 130 along the longitudinal axis X of the tube 120 away from the longitudinal axis X.

[0143] The second embodiment, with several variants, concerns the bow retention device.

[0144] The carrier 100 can be attached to a dome 300 for winding the natural casing 900 in the +X direction. The dome 300 differs from the mandrel according to the prior art, which has a clamping device. To distinguish these mandrels, we refer to the dome according to the prior art as the "clamping dome" and the mandrel according to the invention as the "mandrel 300".

[0145] The second arch 251 is partially separated from the shell 130 by a third slot 252 and a fourth slot 253. The second arch 251 is designed like a bridge and is connected to the shell 130 at least at one bridge end (see Fig. 8a). In an embodiment as shown in Figs. 7, 8, and 9, both ends of the second arch 251 are connected to the shell 130. In a particular embodiment, as shown in Figs. 11, 12, and 14, only one end of the second arch 251 is connected to the shell 130.

[0146] According to one variant of the second embodiment, the second arc 251 is flexible such that, when the natural casing 900 is pulled off, the second arc 251 yields solely due to a radial force exerted by the natural casing 900 over the second retaining element 250. The natural casing 900 can then be pulled off. Alternatively, the second arc 251 is flexible such that, before the natural casing 900 is pulled off, it is deformed inwards towards the longitudinal axis X within the sheath 130, allowing the natural casing 900 to be pulled off without obstruction (Fig. 9).

[0147] It is irrelevant whether the material of the second arch 251 is plastically or elastically compliant. What is important is that the second arch 251 either yields on its own under the force exerted by the natural casing 900 and allows the natural casing 900 to be pulled off, or that the second arch 251 is deformed inwards before the natural casing 900 is pulled off, so that it does not fundamentally impede the natural casing 900.

[0148] Fig. 7 shows that the second arc 251 bulges outwards. Outwards means that the second arc 251 bulges away from the longitudinal axis X and projects outwards from the shell 130, or expands radially to a width B as shown in Fig. 7. r to achieve a size larger than a Kiaiber of the natural intestine 900.

[0149] Fig. 9 shows that the second bend 251 is deformed inwards. Inwards means that the second bend 251 bulges towards the longitudinal axis X and penetrates the tube 120, so that the second bend 251 no longer presents an obstruction.

[0150] The carrier 100 can have at least one first retaining means at the first end region 121 of the tube 120 to prevent the natural intestine 900 from slipping off the sheath 130. According to a variant of the second embodiment, the first retaining means can be a first arc-shaped retaining means 240, which comprises a first arc 241 that curves outwards from the sheath 130 along the longitudinal axis X of the tube 120.

[0151] The carrier 100 can be attached to a dome 300 (Fig. 10) for assembly purposes to thread the natural casing 900 in the direction +X.

[0152] As shown in Fig. 8b, the first arc 241 is partially separated from the shell 130 by a first slot 242 and a second slot 243.

[0153] The first arch 241 is so flexible that when the natural intestine 900 is pulled over the first retaining element 240, it yields solely due to a force exerted radially by the natural intestine 900, allowing the natural intestine 900 to be pulled over.

[0154] Figures 7, 9 and 9b show a curved first arc 241, which can be a partial circle, a partial ellipse or a polyline. The polyline can be composed of several straight lines and / or several curved lines.

[0155] Fig. 7 shows the first arc 241 in a first convex position. Figs. 9 and 9b show the first arc 241 in a second concave position. The advantage of this concave position of the retaining element is that when the natural casing 900 is pulled onto the tube 120, the retaining element does not obstruct the first end region 121 of the tube 120. This allows the natural casing 900 to be pulled onto the tube 120 without obstruction, and the overlap of the natural casing sections 900 is not disturbed during this process. To pull the natural casing 900 onto the tube 120, the tube 120 is placed onto the mandrel 300, as shown in Fig. 10. The second arc 251, when the tube 120 is placed on the mandrel 300, abuts a second stop 380 and jumps from the concave position to a convex position, i.e., curved outwards, as shown in Figs. 7 and 13, and acts as a sliding obstacle.The convex position is a first position and the concave position is a second position of the second arc 251. The first arc 241 should always remain in the second position during the winding of the natural casing 900; therefore, the dome 300 has a groove 320 extending along the longitudinal axis X of the mandrel 120, into which the first arc 241 is pushed until the first arc 241 is in a recess 330 of the dome 300, so that the first arc 241 is not an obstacle during the winding of the natural casing 900 onto the tube 120. When the natural casing 900 is now on the tube 120, the carrier 100 is pulled out of the mandrel 300 in such a way that the first arc 241 abuts a first stop 370 and the first arc 241 jumps from the second position to the first position, i.e., outwards and bulged outwards, as shown in Fig. 14, and again acts as a sliding obstacle.

[0156] In all Figures 7 to 14, only one first arch 241 is shown for the first arch retention device 240. Several, preferably two, first arches 241 can be provided for the first arch retention device 240.

[0157] In all Figures 7 to 14, only one second arch 251 is shown for the second arch retention means 250. Several, preferably two, second arches 251 can be provided for the second arch retention means 250.

[0158] Figures 9a and 9b show a particular embodiment of the first arc retention means 240. A guide means 245 is arranged in the positive X direction, between the first arc 241 and the second arc 251, directly in the immediate vicinity of the first arc 241 inside the tube 120. The width of the guide means 245b is wider than the width of an arc 241b.

[0159] The guide element 245 is designed to be deep enough to be guided securely in the recess 330, and it is designed to be shallow enough to extend beyond the first stop 370 when the tube 120 is withdrawn, without the guide element 245 becoming stuck on the first stop 370. The advantage is that the first arc 241 cannot be accidentally forced outwards into the first position (convex position) during insertion into the recess 330, because the guide element 245 is always advanced when the tube 120 is pushed onto the mandrel 300. For example, for a tube with an outer diameter of 15.2 mm, the arc width 241b can be between 1 mm and 10 mm, preferably around 5 mm. The guide element width 245b can accordingly be between 2 mm and 11 mm, preferably around 6 mm. The depth of the guide element 275 can be between 1mm and 5mm.

[0160] A sliding surface 246 of the guide means 245 can be designed to be flattened in the negative X direction so that it does not get stuck there when being pulled out over the first stop 370.

[0161] Later in the sausage factory, only the outwardly curved second arc 251 needs to be pressed inwards, so that the second arc 251 is returned to its concave position. Then, in the sausage factory, the natural casing 900 can be pulled from the carrier 100 onto the sausage tube without obstruction.

[0162] In a procedure III for mounting the natural casing 900 onto the tube 120, the following steps are carried out:

[0163] - Provision of the natural intestine 900;

[0164] - Provision of the support 100; wherein the support comprises a pipe 120 with a first end region 121 and a second end region 122, wherein the support 100 has a first bend restraint 240 at the first end region 121, wherein the support 100 has a second bend restraint 250 at the second end region 122,

[0165] Mounting the carrier 100 onto a dome 300;

[0166] Pulling the natural intestine 900 onto the tube 120 at the first end area 121 of the tube 120 over the first bend 241;

[0167] Extending the support 100 from the cathedral 300.

[0168] In a process IV for removing the natural casing 900 from the tube 120, which was mounted according to process III, the following steps are carried out:

[0169] III.1 Attaching the carrier 100 to a sausage tube;

[0170] 111.2 Pressing the second arc inwards 251; i.e. into the concave position;

[0171] 111.3 Pulling the natural casing 900 off the tube 120 at the second end area 122 of the tube 120 over the second bend 251.

[0172] Fig. 13 shows that the sheath 130 has a substantially undisturbed surface at the first end region 121. Undisturbed means that the sheath 130 is not interrupted by the presence of a first arc retention element 240. Maintaining an undisturbed sheath 130 in the first end region 121 is advantageous for ensuring the overlapping order of the natural gut pieces 900.

[0173] The overlap order means the sequence of the natural intestine pieces 900 mounted on the carrier 100 with an overlap length of usually 20 cm.

[0174] The overlapping order of the natural intestine pieces 900 is preserved better the less the mantle 130 is disturbed.

[0175] Fig. 13 shows a hatched area 249 at the first end region 121 directly where the arc 241 is located and represents the undisturbed area at the first end region 121. Undisturbed means that the sheath 130 is not interrupted by the presence of the first arc retention device 240.

[0176] Fig. 13 shows that the sheath 130 has a substantially undisturbed area at the second end region 122, which is represented as a hatched area 259. Undisturbed means that the sheath 130 is not interrupted by the presence of a second arc restraint means 250.

[0177] Maintaining an undisturbed sheath at the second end region 122 is advantageous for the stable overlap of the natural gut pieces 900. The less the sheath 130 is disturbed, the better the overlap of the natural gut pieces 900 is preserved. The main region 123 of the sheath 130 remains unchanged and undisturbed. Unchanged and undisturbed means that no changes, such as incisions or depressions, occur at the main region 123 of the tube 120, i.e., in the unhatched area.

[0178] As an alternative to step III.2: The second arc 251 is so flexible that when the natural casing 900 is removed, the natural casing slides out against the flexible second arc 251 simply by stripping the natural casing, without any other action being necessary besides stripping the natural casing 900.

[0179] In this context, the undisturbed area plays an important role. When the natural casing 900 is being wound up in the presence of an obstacle, such as the flexible first arch 241, the undisturbed area 249 has a stabilizing effect, so that any overlap problem of the natural casing 900 is either completely eliminated or at least reduced. Similarly, the undisturbed area plays an important role when removing the natural casing 900 in the presence of an obstacle, such as the flexible second arch 251. The undisturbed area 259 has a stabilizing effect, so that any overlap problem of the natural casing 900 is either completely eliminated or at least reduced.

[0180] Fig. 15 shows a third embodiment of the invention. The support 100 comprises at least one first retaining means at the first end region 121 of the tube 120 to prevent the natural casing 900 from slipping off the sheath 130. The support 100 can additionally or alternatively comprise a second retaining means at the second end region 122 of the tube 120 to prevent the natural casing 900 from slipping off the sheath 130.

[0181] For assembly, the carrier 100 is placed on a dome in order to pull the natural casing 900 in one direction +X onto the jacket 130 of the carrier 100.

[0182] The object of the invention is to provide a carrier for storing natural casings in which the retaining agent cannot fall into the sausage meat.

[0183] The solution to the problem according to the third embodiment of the invention is, as shown in Figs. 15 to 23, that the second retaining means of the carrier 100 is a second flap retaining means 450 and comprises a second flap 451.

[0184] The third embodiment with several variants represents the flap retention device.

[0185] The second flap 451 is strip-shaped. However, to avoid confusion with the strip retention device, the retention device of the third embodiment is referred to as a flap retention device. Because the second flap 451 is always connected to the casing 130 only on one side and in a hinged manner, the term "flap" is appropriate. Fig. 15 shows a schematic top view of the support 100 with flap retention devices 440 and 450. The support 100 has at least one first flap 441 at the first end region 121 and at least one second flap 451 at the second end region 122.

[0186] Fig. 16 shows a schematic side view of the support 100. The at least one first flap 441 extends along the longitudinal axis X in the direction -X as a continuation of the shell 130. The at least one second flap 451 extends along the longitudinal axis X in the direction +X as a continuation of the shell 130.

[0187] Fig. 16a shows a schematic front view of the support 100 at the second end region 122 and has a maximum span with a width B. rThe radius of the first flap 441 is the sum of the outer radius of the tube 120 and the maximum distance of the second flap 451 from the longitudinal axis X. Fig. 17 shows a schematic top view of the first flap retention element 440. The first flap 441 extends essentially to the first tube end 146. An open first recess 442 partially separates the first flap 441 from the rest of the casing 130, so that the first flap 441 is connected to the casing 130 only via a first connection point 443 of the first flap 441. The open first recess 442 means that the recess ends at the tube end 146 and is not completely surrounded by the casing 130.

[0188] Fig. 17a shows a schematic side view of Fig. 17. The first flap 441 is essentially a straight flap without kinks or curves. The first flap 441 forms an angle of 90° ± 70°, preferably 90°, with the longitudinal axis X.

[0189] Fig. 17b shows a schematic side view of Fig. 17. The first flap 441 is essentially a curved flap, which can be a partial circle, a partial ellipse, or a series of curves. Fig. 17c shows a schematic side view of Fig. 17. The first flap 441 is essentially curved and turned back in the +X direction.

[0190] To mount the natural casing 900 onto the carrier 100, the carrier is placed onto a mandrel, referred to here as a clamping mandrel, according to the state of the art. The first flap 441 is clamped into the mandrel's clamping device so that it is guided from an initial open position to a second clamped position. In the second clamped position, the first flap 441 has no obstruction. The natural casing 900 can now be mounted onto the carrier 100. After mounting the natural casing 900 onto the carrier 100, the clamping device can be removed, allowing the first flap 441 to automatically return to its initial open position. It should be noted that such a return to the initial open position is only possible with elastic plastics. With plastics, manual assistance is required to return the flap to its initial position.

[0191] Fig. 18 shows a schematic top view of the second flap retention element 450. The second flap 451 extends essentially to the second pipe end 156. An open second recess 452 partially separates the second flap 451 from the remainder of the jacket 130, so that the second flap 451 is connected to the jacket 130 only via a second connection point 453 of the second flap 451. The open second recess 452 means that the recess terminates at the pipe end 156 and is not completely enclosed by the jacket 130.

[0192] Fig. 18a shows a schematic side view of Fig. 18. The second flap 451 is essentially a straight flap without kinks or curves. The second flap 451 forms an angle of -90° ± 70°, preferably -90°, with the longitudinal axis X. Fig. 18b shows a schematic side view of Fig. 18. The second flap 451 is essentially a curved flap, which can be a partial circle, a partial ellipse, or a series of curves. The second flap 451 according to Fig. 18b is identical to the loose second arc 251 according to Figs. 11, 12, and 14.

[0193] Fig. 18c shows a schematic side view of Fig. 18. The first flap 441 is a slightly curved flap and is essentially directed in the +X direction. Slightly curved means that the radius for the slightly curved second flap 451 of Fig. 18c is significantly larger than the radius for the second curved flap of Fig. 18b.

[0194] To remove the natural casing 900 from the carrier 100, the carrier is placed onto a sausage tube. The second flap 451 is so flexible that when the natural casing 900 is removed via the second flap retaining element 450, the second flap 451 yields solely due to a radial force exerted by the natural casing 900 and moves into a second folded position, allowing the natural casing 900 to be removed simply by stripping it off. "Folded" here means that the second flap 451 is positioned closer to the longitudinal axis X of the tube 120.

[0195] Fig. 19 shows a schematic top view of the second flap retention element 450. The second flap 451 is separated from the mantle 130 by means of a closed second recess 452. Closed means that the second recess 452 is completely surrounded by the mantle 130.

[0196] Fig. 20 shows a schematic top view of the first flap retention means 440. The first flap 441 is rotated laterally from the center of the first recess 442, i.e., from the longitudinal axis X, so that the first flap 441 partially and loosely contacts the shell 130, thus providing a stronger anti-slip barrier than without contact with the shell 130.

[0197] Fig. 20a shows a schematic side view of Fig. 20.

[0198] Fig. 21 shows a schematic top view of the second flap retention means 450. The second flap 451 is rotated laterally from the center of the second recess 452, i.e., from the longitudinal axis X, so that the second flap 451 partially and loosely contacts the shell 130, thus providing a stronger anti-slip barrier than without contact with the shell 130.

[0199] Fig. 21a shows a schematic side view of Fig. 21.

[0200] Fig. 22 shows that the sheath 130 has a substantially undisturbed area at the second end region 122, which is represented as a hatched area 459. The undisturbed area plays an important role in the removal of the natural intestine 900 in the presence of an obstacle such as the flexible second flap 451. The undisturbed area 459 has a stabilizing effect, so that an overlap problem of the natural intestine 900 is either completely eliminated or at least reduced.

[0201] Such an undisturbed area also exists at the first end region 121, but this is not necessarily required for stabilizing the mounting of the natural intestine 900, because the first flap 441 is clamped there and is essentially out of the way and does not interfere. Fig. 23 is a schematic side view of the carrier 100 with flap retention means and with a natural intestine 900 already mounted on it.

[0202] Figures 12 to 23 show either only one first flap 441 or only one second flap 451. Several, preferably two, first flaps 441 can be arranged at the first end region 121. Similarly, several, preferably two, second flaps 451 can be arranged at the second end region 122.

[0203] In a procedure V for mounting the natural casing 900 onto the tube 120, the following steps are carried out:

[0204] - Provision of the natural intestine 900;

[0205] - Provision of the support 100; wherein the support comprises a tube 120 with a first end region 121 and a second end region 122, wherein the support 100 has a first flap retention means 440 with a first flap 441 at the first end region 121, wherein the support 100 has a second flap retention means 450 with a second flap 451 at the second end region 122,

[0206] - Attaching the carrier 100 to a clamping dome;

[0207] - Clamping the first flap 441 in a clamping device of the clamping mandrel;

[0208] - Pulling the natural intestine 900 onto the tube 120 at the first end region 121 of the tube 120 over the first valve retention device 440;

[0209] - Unplugging the carrier 100 from the clamping dome.

[0210] In a procedure VI for removing the natural casing 900 from the tube 120, which was mounted according to procedure V, the following steps are carried out:

[0211] - Changing the second strip 153 from a closed second position to an open first position;

[0212] - Attaching the carrier 100 to a sausage tube; - Removing the natural casing 900 from the tube 120 at the second end area 122 of the tube 120 via the second flap retention device 450.

[0213] Other commonly known restraint devices are shown in Figs. 24a, 24b and 24c. Fig. 24a shows a rubber ring 500, which is known from the prior art as a restraint device.

[0214] Fig. 24b shows an insert 600, which is known from the prior art as a retention device. The insert 600 is cylindrical and has a flat, circular stopper on one side. The insert 600 fits into the tube 120 and is fluid-permeable.

[0215] Fig. 24c shows a cone-shaped part 700, which is known from the prior art as a retention device. DE202016100772U1 describes a pipe fitting designed as a cone-shaped part 700. The cone-shaped part 700 is fluid-permeable, funnel-shaped, and longitudinally slotted, making it spring-elastic in its diameter. The cone-shaped part 700 can additionally have a flat or conical circular stopper on its widened side.

[0216] The subdivision of sub-areas 121, 122 and 123 applies to all embodiments of this invention.

[0217] The material for the inventive pipe 120 can comprise, at least partially, a flexible, environmentally friendly, biodegradable and food-grade plastic.

[0218] Biodegradable means home compostable and / or industrially compostable. Examples of such biodegradable plastics are polybutylene succinate and polylactic acid, which are bio-based plastics and can be produced from renewable resources. Polyethylene can also be produced from renewable resources.

[0219] Examples of fossil-based plastics include polyamide and polyolefin. Polyethylene is another fossil-based plastic. Polyurethane is also used in this context and is a fossil-based plastic. Chemically sound combinations of these plastics are possible.

[0220] In all embodiments, at least the tube 120 and the respective second retaining element are formed in one piece. That is, the second retaining element is always an integral part of the support 100.

[0221] A combination of retention devices is possible and advisable. For example, according to Table 2, the following retention devices can be provided in the first end section 121 and in the second end section 122 of pipe 120:
