Abstract: 353,162. Winding fabrics ; cutting. RIEDER, J., 2A, Flieht, Vohwinkel, Germany. May 28, 1930, No. 16466. [Classes 31 (i) and 42 (ii).] In a machine for winding braid on cards and the like of the kind wherein feeding the cards into holders, clamping the braid end against the card, winding, cutting the braid by pivoted blades and delivery of the wound package are automatically effected; the braid clamp and shears are arranged on the card holders thus ensuring an accurately measured length of braid on each card. The last but one convolution of braid on each card is diagonal and means are included for pulling this convolution over the severed end of the braid to prevent it unwinding. Cards stacked in a magazine 3 and pressed upwards by a spring 115 and plunger 112, Fig. 5, are fed by a reciprocating slide 53 into slits in the card holders 78, 61, Fig. 1, on shafts 20, 6 rotated by gears 21, 22, an intermediate shaft 19 being driven by gears 16, 17, 18 through an adjustable coupling 108, 110 having screw bolts 109 and arcuate slots. The gear 17 is an idler for varying the ratio between shafts 13, 19, the former being driven by a pin wheel 12, a Maltese cross 14 on the shaft 13 engaging the pins during part of each revolution of the wheel 12 and a segment 15 during the remainder, when the holders 78, 61 are held with their slits horizontal. A slide 79 on the holder 78 carries a lever 80 with a spring 83, an abutment 82 for clamping the card and a resilient finger 81 for holding the starting end of the braid against the card being wound. The lever 80 is moved by a collar 76 rotating with the holder 78 and is controlled by a lever 75. The holder 61 is similar, a lever 58 and collar 59 controlling a lever 117, to which is connected one blade 63 of the shears 62, 63, aid on which is a resilient finger 64 which clamps the braid being cut. The collar 59 carries a hook-ended rod 66 which pulls one of the convolutions over the severed end, a cam and pins 67, 68 maintaining the finger 64 in position against the pressure of a spring 69. The braid passes between a roller 93 and a rod 94 of a stopmotion operating when a knot in the braid moves the rod 94 on a detent 96 and allows a spring 99 to turn levers 101, 103 and separate clutch halves 106, 107 of the main drive 7, 8. The braid passes to a traversed guide 88 with a drag-plate 90 adjustable for various thicknesses of braid by screws 92 bearing against an arm 89 connected to the plate 90. The traverse, the card feed, and the collars 76, 59 of the card holders are respectively actuated by cams 27, 24, 23, 25, levers 36, 33, 34, 35 on shafts 32, 29, 31, 30, by rods 40, 37, 39, 38 on which are fixed collars 42, and by springs 41. The traverse rod 40 moves a lever arm 84, a rock shaft 85 and a lever arm 86 thus reciprocating the guide 88. The card feed 37 actuates a lever 43, a hollow shaft 44, bevel gears 45, 46, a rock shaft 47, bevel gears 48, 49, a rock shaft 50 and a lever 51 to reciprocate the slide 53. The rod 39 actuates a lever 70 on a shaft 71, passing through the hollow shaft 44, bevel gears 72, 73 and a rock shaft 74 with a forked lever arm 75 controlling the collar 76. The rod 38 actuates a lever 54 on a vertical shaft 55, bevel gears 56, 57 and a forked lever arm 58 controlling the collar 59.
