[0029] First reference Figure 1 and Figure 2 The reel holding creel 10 comprises a frame adapted to support a plurality of reels 12 on which corresponding yarns are wound. The yarn unwound from the reels 12 is supplied to a textile machine (not shown), such as a braiding machine or a knitting machine.
[0030] The frame comprises a lower base 14 and an upper base 16, interconnected by a front post 18b and two rear posts 18a, each having a tubular profile with a circular cross-section. The lower base 14 comprises a lower transverse beam 14a and lower longitudinal beams 14b welded together in a T-shape. The lower base 14 is supported on three pivot wheels 20 secured to the ends of the T. Similarly, the upper base 16 comprises an upper transverse beam 16a and upper longitudinal beams 16b welded together in a T-shape.
[0031] The rear pillar 18a is laterally fixed to the ends of the lower cross member 14a and the upper cross member 16a. The front pillar 18b is laterally fixed to the free ends of the lower side member 14b and the upper side member 16b.
[0032] In the first exemplary embodiment described herein, the reels 12 are conventionally supported in vertical rows on the rear post 18a. Specifically, each reel 12 is mounted in a free-wheeling manner to a corresponding horizontal pin 32 ( Figure 2 ), the horizontal pin 32 is connected to one of the rear posts 18a via a spool holder 34. For greater clarity, Figure 1 and Figure 2 , a horizontal pin 32 is shown connected to one of the rear posts 18a (without a reel mounted thereon).
[0033] The front post 18b supports a plurality of spacers 36 which, in this embodiment, are conventionally formed as discs.
[0034] Now special reference Figure 3-Figure 5 Each yarn spacer 36 is conventionally provided with an axial annular seat 36a in which a corresponding yarn guide eyelet 38 is received. The yarn guide eyelet 38 is suitable for guiding the yarn unwound from the reel into the textile machine. The yarn spacer 36 prevents the yarn balls formed when the yarn is withdrawn from the reel from the spool from entanglement.
[0035] Each yarn spacer 36 is secured to the front post 18b by a corresponding bracket 40 having a post receptacle 42 defined therein and in which the front post 18b is received.
[0036] According to the invention, each bracket 40 has at least one through hole 44 opening into the post receptacle 42 and is fixed to the front post 18 b by at least one threaded element 46 inserted into a respective one of the through holes 44 .
[0037] In this embodiment, two through holes 44 vertically aligned with each other are advantageously formed at different heights in the bracket 40. Advantageously, the through holes 44 have respective axes A ( Figure 4 ), the axis A extends in a substantially radial direction relative to the front post 18b housed in the post receptacle 42.
[0038] In this embodiment, the through hole 44 is threaded and the threaded element 46 includes a set screw that is tightened in the threaded through hole 44 in a manner abutting against the outer surface of the front post 18b, thereby securely locking the bracket 40 to the front post 18b received in the post receptacle 42.
[0039] In the embodiment described herein by way of example, the bracket 40 is formed from sheet metal.
[0040] exist Figures 1-6 In the first embodiment shown, the front post 18b preferably has a tubular profile with a circular cross-section, and the post receiving seat 42 comprises a lower U-shaped seat 42a and an upper U-shaped seat 42b aligned with each other, which surround the front post 18b at different heights and are interconnected on one side by a connecting portion 48 of a metal plate and on the other side by a mounting portion 50 of a metal plate. The mounting portion 50 has a vertical wall 50a to which the yarn spacer 36 is fixed. In more detail, the vertical wall 50a has a circular opening 52, which accommodates the axial annular seat 36a, in which the yarn guide eyelet 38 is received. The yarn spacer 36 is fixed to the vertical wall 50a by two screws 54, which engage corresponding two radial recesses 52a ( Figure 5 The through hole 44 is formed on a tab 50b of the metal plate that projects at a right angle from an inner vertical edge of the vertical wall 50a along the post receiver 42 in such a manner as to face the front post 18b accommodated in the post receiver 42.
[0041] Advantageously, the mounting portion 50 has a horizontal wall 50c for maneuvering and orienting the bracket 40 by a user, the horizontal wall 50c being connected to the vertical wall 50a by a curved wall 50d.
[0042] Fastening means 56 are used to connect the rear and front posts 18a, 18b to the lower and upper bases 14, 16 in a manner known per se.
[0043] Specific reference Figure 6 Each fastening device 56 comprises a U-shaped bracket 58 provided with two horizontal side portions 58a and provided with a vertical base portion 58b. The ends of the horizontal side portions 58a facing away from the vertical base portion 58b are welded laterally to a corresponding one of the lower cross member 14a, the lower longitudinal beam 14b, the upper cross member 16a and the upper longitudinal beam 16b ( Figure 6 The horizontal side portions 58a are provided with corresponding aligned bracket openings 60 defined to accommodate the corresponding columns ( Figure 6 The rear and front posts 18a and 18b are axially locked in the respective U-shaped brackets 56 by means of locking screws 62, which are externally inserted into through-channels 64 formed in the vertical base portion 58b and engage locking nuts 66 on the opposite side of the vertical base portion 58b. By tightening the locking screws 62, the locking nuts 66 abut against the inner surface of the vertical base portion 58b, while the tips of the locking screws 62 abut against the outer surface of the respective posts, in such a way that the posts are axially locked in the U-shaped brackets 58.
[0044] In practice it has been found that the spool holding creel for a weaving process according to the invention fully achieves the desired objectives.
[0045] In particular, since the reel holding creel for weaving processes according to the present invention only requires one front post to support the yarn spacer device with yarn guide eyes, the reel holding creel for weaving processes according to the present invention is lighter and cheaper than the known solutions mentioned in the background part of this specification.
[0046] Furthermore, the yarn spacer with the yarn guide eyelet can be easily oriented into the desired position about the axis of the front post by momentarily loosening the fixing screw.
[0047] exist Figure 7-12 A second embodiment of a spool holding creel 110 is shown in FIG.
[0048] Now specific reference Figure 12 The front post 118b of this second embodiment is provided with a peripheral wall defining a longitudinal groove 180. The peripheral wall of the front post 118b is primarily cylindrical, except for a flat side 118b' along the front post that defines the longitudinal groove 180. The longitudinal groove 180 leads to an interior cavity 182 of the front post 118b, which is provided with a bottom wall 184.
[0049] In this second embodiment, the bottom wall 184 is parallel to the flat side 118b' and is connected to the inner surface of the peripheral wall of the front post 118b by means of a reinforcing wall 186. The longitudinal groove 180 is provided with two raised edges 180a protruding inwardly.
[0050] In this second embodiment, the two through-holes 144 are unthreaded, and each threaded element 146 comprises a screw that is inserted into a corresponding one of the through-holes 144 (preferably through a washer 188) and into the longitudinal groove 180. An insert 190 is received in the inner cavity 182, and the screw threadingly engages a corresponding threaded hole 192 of the insert in such a manner as to securely lock the bracket 140 to the front post 118 b received in the post receptacle 142.
[0051] In this second embodiment, the support 140 is also made of sheet metal. The post receptacle 142 is delimited by a vertical wall 150a of the sheet metal to which the spacer 136 is fixed, and a tab 150b protruding at a right angle from the vertical edge of the vertical wall 150a, in which the through hole 144 is formed.
[0052] Similar to the previous embodiment, the vertical wall 150a has a circular opening 152 that accommodates the axial annular seat 136a, in which the yarn guide eyelet 138 is received, and the yarn spacer 136 is fixed to the vertical wall 150a by two screws 154, which engage two corresponding radial recesses 152a extending from the periphery of the circular opening 152 in diametrically opposite directions.
[0053] Also in this second embodiment, two through holes 144 vertically aligned with each other are formed on the tab 150b at different heights and are engaged by corresponding two threaded elements 146. The axis A' ( Figure 10 ) advantageously extends in a substantially radial direction relative to the front post 118b received in the post receptacle 142.
[0054] Also in this second embodiment, the stand 140 is provided with a horizontal wall 150c for manipulating and orienting the stand 140 by a user.
[0055] In this second embodiment, the rear post 118a has a tubular profile with a circular cross-section and is connected to the lower base 114 and the upper base 116 as in the previous embodiment.
[0056] To connect to the lower base 114 and the upper base 116, as Figure 12As shown, the ends of the front posts 118b are received in corresponding U-shaped brackets 158 in a manner similar to the previous embodiment. Also in this case, the front posts 118b are secured to each U-shaped bracket 158 by means of locking screws 162, which are externally inserted into through-holes 164 formed in the vertical base portion 158b of the U-shaped bracket 158 and engage nuts 166 on opposite sides of the vertical base portion 158b. The only difference from the previous embodiment is that in this case, the locking screws 162 are inserted into longitudinal grooves 180, and the distal ends of the locking screws abut against a bottom wall 184 of the inner cavity 182 of the front posts 118b, rather than against the outer surface of the front posts 118b.
[0057] A few preferred embodiments of the invention have been described herein, but of course, those skilled in the art may make many variations within the scope of the claims.
[0058] For example, all of the above nuts can be dispensed with if the holes into which the corresponding screws are inserted are threaded.
[0059] Furthermore, although the axis of the through hole preferably extends in a substantially radial direction relative to the front post received in the corresponding post receptacle, the bracket can of course be locked to the front post even if the axis of the through hole is not radial, as long as the axis of the through hole intersects the front post.
[0060] However, in some cases a single threaded element is sufficient to securely lock the bracket to the anterior post.
[0061] Of course, the frame of the spool holding creel can be modified extensively (e.g. the rear post can be replaced by another structure such as a continuous wall, a lattice frame, etc.) provided that the frame of the spool holding creel has a front post to which the spacer device is fixed.
