Opposite ends of :the strip. meet In Figs. 6 to 14 are shown details of the apparatus employed for packing the pile fabric P on the rack 20. The winding and turning device has a frame formed by two pairs of upright bars 60 secured at opposite ends of a rectangular base plate 62. The upper ends of the bars '60 are joined by

cross-bars

63 and 64 to form a rigid open rectangular frame structure. At each end of the frame is a circular ring 33 formed by four arcuate strips or plates 34 as shown in Fig. 8. The plates are supported by the horizontally disposed arms 35 and the

vertical arms

36, 37. Arms 35 are joined to bars 60. Arm 37 is joined to crossbar 63 and arm 36 is joined to plate 62. The ring 33 fits into the circular groove 38 of a circular plate 39 which is best shown in Fig. 14. Plate 39 is thus rotatably mounted in ring 33. Supported on plate 39 and rotatable therewith is a rack clamping device 49. This device, as best shown in Figs. 12 and 13, includes a base plate 50 having a flange 51. The flange is provided with apertures 52in which are engaged rivets or bolts 53 which I 58 anchored in plate 50. Wing nuts 59 are threaded on bolts 58. The rectangular plate 56 has a recess 61 into which fits the bridge portion 26 of the rack arms 25.

When the rack is mounted in the clamping device 49 as shown in Figs. 6, 8 and 9, the rack is rotatable on a horizontal axis in the rings 33 at both ends of the frame. The fabric P may be manually inserted into the corresponding slots of the respective arms 25 and the wires 44 may then be advanced through the passages to pierce the selvaged ends S of the fabric P and thus secure the fabric in the rack. The wires 44 are advanced by the mechanism which will now be described.

' In plate 39 are four slots 66 as best shown in Figs. 7 and 8. Through each of. these slots passes an arm or lever 67. There are four such levers provided at each end of the frame. The levers are pivotally mounted-in brackets 68 which are secured to the plate'39. The levers 67 serve as handles for advancing the wrench heads or elements 70 in outward radial directions with respect to each plate 39. The wrench'heads 70 are best shown in Figs. 10 and 11. Each wrench head is a hollow, rectangular body formed on the end of lever 67 and disposed perpendicular thereto. Wire 44 passes through the opening 71 in wrench head 70. Within the opening are disposed two U-shaped leaf springs 72. The outer ends of the springs are secured to the wall of opening 71 and the free ends bear on the jaws 74. Each jaw 74 has inwardly extending teeth 75 which are directed so that the Wire 44 can be advanced by the lever 67 when the lever is op erated, Each jaw 75 pivots on a pintle 76 which extends through the upper and lower sides of the wrench head 70. In Fig. 11 the extent of advancement of wire 44 each time the lever 66 is operated is indicated by dotted lines.

After each forward movement of the wire the wrench head moves baclcwardly or radially inward with respect to plate 39 Without affecting the position of wire 44.

In Figs. 7 and 9 is shown the disposition of four Wires designated 44*, 44 44, and 44 The wire is passed through to respective Wrench heads 70 to enter the passages 45 in the turned edges 42 of each arm 25. 'The respective arms are designated 25, 25*, 25 and 25 It .will be noted that

wires

44 and 44 are disposed inwardly a short distance with respect to

wires

44 and 44 This is made possible by forming the

arms

25 and 25 with greater width than the

arms

25 and 25, so that the turned edges 42 of the

arms

25 and 25 are disposed inwardly a short distance with respect to the turned edges 42 of

arms

25 and 25 Since wires 44*, 44 are respectively parallel to

wires

44 and 44 the wires do not interfere with each other. The wires are quite stiff so that they extend radially as shown in Figs. 7 and 8, but they are flexible enough to be twisted to form the ties 46, 47 shown in Fig. 1.

Each time the selvage edge of the fabric is inserted in a slot 40 the appropriate lever 67 is manually operated to advance the pointed end 48 of wire 44 through the fabric. As each pair of coplanar arms on opposite sides of the rack is loaded with fabric, the rack is manually turned so that the next slots 46) in the following arms 25 may be engaged by the fabric being wound on the rack. After the rack is completely packed with the spirally wound fabric the clamping plates 56 are removed to release the rack. The ends of the wires extending out of the passages 25 at each end of each arm are tied together as shown in Fig. 1.

The invention herein disclosed is related to that covered in copending patent application Serial No. 669,519 filed July 2, 1957 on Machine for Packing Pile Fabrics.
