[0026] The utility model relates to a kind of warp bundling machine 1 and a kind of warp bundling equipment 2 including this warp bundling machine (warping machine) 1 and warp bundling frame (warping frame) 3.

[0027] Warp bundling machine 1 is used to join together the first warp yarn 4.1 of the first warp sheet 4 with the second warp yarn 5.1 of the second warp sheet 5 by knot K, which can be single knot or double knot, the first warp sheet 4 and the second warp sheet 5 are located on parallel first warp sheet plane P4 and second warp sheet plane P5 respectively, and the bundling (warping, tying) process is repeated in an automatic manner on all warp yarns on the two first warp sheet 4 and second warp sheet 5.

[0028] In the bundling process, the warp yarns on the first warp sheet 4 and the second warp sheet 5 are first stretched and clamped in the warp bundling frame 3, and each warp yarn of each warp sheet 4, 5 is clamped in a pair of two tracks 31, 32 of the warp bundling frame 3, and each pair of tracks 31, 32 is spaced apart along the extension direction Y4, Y5 of the warp yarn within the warp sheet 4, 5. Figure 4 A part of the warp bundling frame 3 is shown. The clamped warp yarns of the warp sheet 4, 5 extend parallel to each other along the extension direction Y4, Y5, respectively, and together define the first warp sheet plane P4 and the second warp sheet plane P5, respectively. The warp bundling machine 1 is then mounted on the warp bundling frame 3.

[0029] The warp bundling machine 1 comprises a main body 11 defining a front outer surface 11A turned towards the warp sheet 4, 5 in the bundling configuration and a side outer surface 11B turned towards the tracks 32 of the warp clamping frame 3, which clamp the paired first warp yarn 4.1 and second warp yarn 5.1 tied together after knot K is tied.

[0030] The warp bundling machine 1 comprises a separation device 6, a knot tying device 7, a feeding device 8 and an extraction device 10 mounted on the main body 11. All these devices comprise components movable with respect to the main body 11, which are driven by a common motor or their own motor and controlled by a common controller of the warp bundling machine 1.

[0031] The separation device 6 comprises two spindles 61 and 62, each spindle 61, 62 being configured to separate the warp yarn 4.1, 5.1 from the respective warp sheet 4, 5, the separated warp yarn 4.1, 51 still being clamped and tensioned in two spaced apart tracks 31, 32 of the warp bundling frame 3. The spindle 61 defines a spindle axis X61 about which the spindle 61 rotates for yarn separation. The spindle 62 defines a spindle axis X62 about which the spindle 62 rotates for yarn separation. The spindle axes X61 and X62 are parallel to each other but offset in a transverse direction Z perpendicular to the first warp sheet plane P4 and the second warp sheet plane P5. The spindle axes X61 and X62 are parallel to the first warp sheet plane P4 and the second warp sheet plane P5.

[0032] As shown in Figure 4 Fig. 1, when the warp stranding machine 1 is mounted in the stranding configuration on the warp stranding frame 3, the spindle axis X61 of the spindle 61 is offset from the associated first warp sheet plane P4 in a transverse direction Z perpendicular to the first warp sheet plane P4. The guide surface 611 of the rotating spindle 61 intersects the first warp sheet plane P4. The spindle axis X62 of the spindle 62 is offset from the associated second warp sheet plane P5 in the transverse direction Z perpendicular to the second warp sheet plane P5. The guide surface 621 of the spindle 62 intersects the second warp sheet plane P5.

[0033] The feed device 8 of the warp stranding machine 1 is configured to move the main body 11, and thus the separating device 6, the knotting device 7, the extraction device 10, in a feed direction X1 parallel to the first warp sheet plane P4 and the second warp sheet plane P5 and perpendicular to the direction of extension Y4, Y5 within the warp sheets 4, 5. The feed direction X1 is turned towards the warp sheets 4, 5 in the stranding configuration of the warp stranding machine 1 and defines a front direction.

[0034] The knotting device 7 is located outside the space between the first warp sheet plane P4 and the second warp sheet plane P5.

[0035] The warp stranding machine 1 is further equipped on its front outer surface 11A with a deflector 12 and on its side outer surface 1 IB with an extraction recess 13. The deflector 12 consists of two metal parts 12A and 12B. The part 12B delimits a first guide surface 121, a second guide surface 124 and a third guide surface 125. Two first opposite side surfaces 121A, 121B, two second opposite side surfaces 124A, 124B and two arms 127 are also formed on the part 12B. The first opposite side surface 121B and the two second opposite side surfaces 124A, 124B are planes parallel to the transverse direction Z. The parts 12A and 12B are fixed together by means of screws 128. The two arms 127 are provided on the part 12B and are fixed to the main body 11 with screws 14, which means that the deflector 12 can be detached from the main body 11 by unscrewing the screws 14.

[0036] During the stranding process, the deflector 12 moves together with the main body 11 and the warp stranding machine 1 in the feed direction X1 relative to the warp sheets 4, 5. The deflector 12 does not move relative to the main body 11 when fixed to the main body 11. The first guide surface 121 is delimited by the first opposite side surfaces 121A, 121B in a lateral direction Y parallel to the direction of extension Y4, Y5. The first guide surface 121 is a plane extending parallel to the first warp sheet plane P4 and the second warp sheet plane P5, thus parallel to the lateral direction Y and between the first warp sheet plane P4 and the second warp sheet plane P5.

[0037] The first guide surface 121 rotates in a first lateral direction Z1 parallel to the lateral direction Z. Preferably, the front end of the first guide surface 121, i.e. the end of the first guide surface 121 in the feed direction X1, ends at a level (height) along the lateral direction Z, which is located between the levels of the spindle axis X61 and the spindle axis X62 in the lateral direction Z.

[0038] The second guide surface 124 is a plane inclined relative to the first warp plane P4 and the second warp plane P5 and relative to the feed direction X1. The inclination angle A of the second guide surface 124 is 25°. The second guide surface 124 rotates in a second lateral direction Z2, which is parallel to the lateral direction Z and opposite to the first lateral direction Z1. The second guide surface 124 extends at least partially between the first guide surface 121 and the extraction recess 13 along the lateral direction Z. Preferably, the rear end of the second guide surface 124, i.e., the end of the second guide surface 124 in the rearward direction X2, which is opposite to the forward direction defined by the feed direction X1, is located laterally horizontally in the lateral direction Z of the extraction recess 13.

[0039] The third guide surface 125 is disposed between the first guide surface 121 and the second guide surface 124 along the feed direction X1, and is coplanar with the second guide surface 124. The third guide surface 125 rotates in the second transverse direction Z2.

[0040] like Figure 4 and Figure 5 As shown, the first guide surface 121, the second guide surface 124, and the third guide surface 125 all intersect the deflection plane P9C, which is parallel to the feed direction X1 and parallel to the lateral direction Z. The first guide surface 121 extends at least partially at a lateral level along the lateral direction Z, which is different from the lateral level of the second guide surface 124. In particular, the first guide surface 121 extends entirely at a lateral level different from the lateral level of the second guide surface 124. In other words, the first guide surface 121 and the second guide surface 124 are completely offset from each other along the lateral direction Z. The first guide surface 121 and the second guide surface 124 are completely offset from each other along the feed direction X1.

[0041] The warp tying device 2 further comprises a rope 9 extending partly between the first warp sheet plane P4 and the second warp sheet plane P5. The rope 9 can be a twisted rope or a nylon rope, or any type of rope. The rope 9 extends perpendicular to the yarn extension direction Y4, Y5 and covers the entire width of the warp sheet 4, 5 along the feed direction XI at the start of the tying process. The two ends of the rope 9 are fixed relative to the warp tying frame 3, which means that the warp tying machine 1 moves relative to the rope 9 when the feed device 8 moves the warp tying machine 1 relative to the warp sheet 4, 5 clamped in the warp tying frame 3. In other words, the deflector 12 and the extraction recess 13 are movable in the feed direction XI relative to the warp tying frame 3 and thus relative to the rope 9 together with the main body 11 during the tying process.

[0042] Preferably, the rope 9 is partly stretched and extended in a first plane P9A and a second plane P9B, the first plane P9A being parallel to and located between the first warp sheet plane P4 and the second warp sheet plane P5, the second plane P9B being located outside the space extending between the first warp sheet plane P4 and the second warp sheet plane P5.

[0043] As shown in Figure 3 and Figure 8 the rope 9 is shown in dashed lines in Figure 8 , the rope 9 cooperating with the first guide surface 121, the second guide surface 124 and the third guide surface 125 such that the rope 9 is deflected from a first transversal level Z9A corresponding to the first plane P9A to a second transversal level Z9B corresponding to the second plane P9B. In other words, the first transversal level Z9A is located between the first warp sheet plane P4 and the second warp sheet plane P5 and the second transversal level Z9B is located outside the space between the first warp sheet plane P4 and the second warp sheet plane P5.

[0044] The deflection of the rope 9 occurs at the level of the front outer surface 11A of the warp tying machine 1. In particular, as shown in Figure 5 , the rope 9 is located between the first transversal level Z9A and the second transversal level Z9B at a longitudinal level of the knotting device 7 along the feed direction XI.

[0045] The first plane P9A and the second plane P9B are parallel to the first warp sheet plane P4 and the second warp sheet plane P5 and the second plane P9B is located at the level of the extraction recess 13 along the transversal direction Z. The extraction recess 13 extends along the transversal direction Z at the second transversal level Z9B.

[0046] The second plane P9B is offset with respect to the first plane P9A along the transverse direction Z. In other words, the second transverse level Z9B is offset with respect to the first transverse level Z9A along the transverse direction Z. This means that the two ends of the cord 9 are fixed at respective different transverse levels, in particular in different planes P9A, P9B. The cord 9 is located on a rear side of the end-to-end strapping machine 1 with respect to the feed direction X1, substantially extending in the second plane P9B. The cord 9 is located on a front side of the end-to-end strapping machine 1 with respect to the feed direction X1, substantially extending in the first plane P9A, i.e. between the first and second end pieces 4, 5.

[0047] Preferably, by cooperation with the first guide surface 121, the second guide surface 124 and the third guide surface 125, the cord 9 extends in the deflection plane P9C, which ensures that the cord 9 does not exert a lateral force on the end-to-end strapping machine 1. The first and second opposite side surfaces 121 A, 121 B and 124A, 124B laterally, i.e. along the lateral direction Y, guide the cord 9 in the deflection plane P9C when the cord 9 cooperates with the deflector 12.

[0048] Preferably, the main body 11 further comprises opposite side surfaces 111, 112 which laterally guide and / or protect the cord 9 from the outside of the end-to-end strapping machine 1 when the cord 9 extends in the second plane P9B.

[0049] All surfaces of the deflector 12 which cooperate with the cord 9, in particular the first guide surface 121 and the second guide surface 124, are located at the same lateral level between the knotting device 7 and the track 32 of the pair of end-to-end knotted end pieces. In particular, the first guide surface 121 and the second guide surface 124 are located at the same lateral level between the knotting device 7 and the side outer surface 1 1 B of the main body 11 along the lateral direction Y.

[0050] Before starting the strapping process, the end-to-end strapping machine 1 equipped with the deflector 12 is mounted on the end-to-end strapping frame 3 on which the two end pieces 4, 5 are clamped and the cord 9 is mounted between the first end piece plane P4 and the second end piece plane P5 and fixed with respect to the end-to-end strapping frame 3. The cord 9 then cooperates with the deflector 12, in particular with the first guide surface 121 and the second guide surface 124.

[0051] In the strapping configuration, when the end-to-end strapping machine 1 moves with respect to the end-to-end strapping frame 3 due to the feed device 8, the cord 9 slides over the deflector 12, in particular over the first guide surface 121 and the second guide surface 124. During the strapping process, the main body 11, the deflector 12 and the extraction recess 13 jointly move with respect to the end-to-end strapping frame 3 along the feed direction X1.

[0052] Due to the movement of the end-to-end bundling machine 1 along the feed direction XI with respect to the first end-to-end piece 4, a first end-to-end yarn 4.1 of the first end-to-end piece 4 (corresponding to the foremost end-to-end yarn of the first end-to-end piece 4) comes into contact with the guide surface 611 of the spindle 61. As the spindle 61 advances and rotates with respect to the spindle axis X61, the first end-to-end yarn 4.1 is separated from the end-to-end piece 4. The first end-to-end yarn 4.1 is then severed and the portion of the first end-to-end yarn 4.1 extending between the track 32 and the end of the severed first end-to-end yarn 4.1 is transferred to the knotting device 7.

[0053] At the same time, due to the movement of the end-to-end bundling machine 1 along the feed direction XI with respect to the second end-to-end piece 5, a second end-to-end yarn 5.1 of the second end-to-end piece 5 (corresponding to the foremost end-to-end yarn of the second end-to-end piece 5) comes into contact with the guide surface 621 of the spindle 62. As the spindle 62 advances and rotates with respect to the spindle axis X62, the second end-to-end yarn 5.1 is separated from the end-to-end piece 5. The second end-to-end yarn 5.1 is then severed and the portion of the second end-to-end yarn 5.1 extending between the track 32 and the end of the severed second end-to-end yarn 510 is transferred to the knotting device 7.

[0054] The knotting device 7 causes the severed first end-to-end yarn 4.1 and the severed second end-to-end yarn 5.1 to form a knot K, while the pair of first end-to-end yarn 4.1 and second end-to-end yarn 5.1 knotted together is still clamped in the track 32 of the end-to-end bundling frame 3.

[0055] The knot K is tightened by the extraction device 10 which pulls the pair of first end-to-end yarn 4.1 and second end-to-end yarn 5.1 knotted together into the extraction recess 13, i.e. in the rear direction X2.

[0056] Each pair of first end-to-end yarn 4.1 and second end-to-end yarn 5.1 knotted together forms a loop L defined by the knot K and the track 32. At the second transverse level Z9B, the cord 9 extends through all the loops L formed by the pairs of first end-to-end yarn 4.1 and second end-to-end yarn 5.1 knotted together, which ensures the correct order of the knotted end-to-end yarns adjacent to each other along the feed direction XI without entanglement.

[0057] The end-to-end bundling machine 1 continues the bundling process on all the end-to-end yarns of the first end-to-end piece 4 and of the second end-to-end piece 5. When the bundling process of all the end-to-end yarns 4.1, 5.1 of the end-to-end pieces 4, 5 is completed, the cord 9 is removed from the knotted end-to-end yarns.

[0058] The second guide surface 124 protects the cord 9 in the deflection portion of the cord 9. The first and second opposite side surfaces 121A, 121B, 124A, 124B ensure a good alignment of the cord 9 parallel to the feed direction XI with the extraction recess 13 and ensure a good positioning of the cord 9 with respect to the separation device 6 and the knotting device 7 of the end-to-end bundling machine 1, thus avoiding any interference between the movable parts of the end-to-end bundling machine 1 and the cord 9.

[0059] The deflector 12 is removably fixed to the warp strapping machine 1. In other words, in the case in which the rope 9 is not used for the strapping process of the warp strapping machine 1, the deflector 12 can be removed from the main body 11 by unscrewing the screw 14.

[0060] The first and second guiding surfaces have been described as planes having a straight line contact with the rope 9. In a not shown variant of the present invention, the first guiding surface 121 and / or the second guiding surface 124 can be a circular surface having a curved line contact with the rope 9.
