摘要： Apparatus is disclosed for separating hosiery produced on a circular knitting machine. The hosiery is knitted as a continuous tubular fabric with a weakened portion being formed between articles to be separated. The separating apparatus includes a frame mounted below the knitting machine, a gripping and separating arm pivotally mounted on the frame, and a fixed clamping arm mounted on the frame below the gripping and separating arm. The gripping arm and the clamping arm each include a pair of jaws which are intermittently actuated to engage the tubular fabric adjacent the weakened portion of the articles. The gripping arm is pivoted to exert an arcuate pulling force upwardly away from the clamping arm to cause the articles to be separated along their weakened portions. The separation action is arranged so as to prevent stretching of the fabric coming from the knitting machine. A fabric guide and a pneumatic transport for the separator are also disclosed.

摘要： 782,784. Testing fabrics. MARVEL SPECIALTY CO. Sept. 15, 1955 [Oct. 22, 1954], No. 26386/55. Class 42 (2). [Also in Groups XIX and XXXVII] The loop courses in knitted fabric are counted by extending the fabric to a tension whereat the intertwined end portions of side-by-side yarn course loops are extended into a series of parallel course-defining ridges on one side of the fabric, and passing a ridge-impulse course-counting mechanism across and in contact with the ridges. Fabric tensioning. As shown, Fig. 1, the fabric 10 to be examined is placed across rubber-. faced rollers 8, 9 and is held against roller 8 by a spring loaded roller 14 while roller 9 is manually turned clockwise to tension the fabric. Roller 9 is held against reverse rotation by a ratchet and pawl mechanism. Roller 8 is carried by a sleeve loose on a shaft 3 but is restrained from rotation by a spring 23 acting on a lever 11 fixed to the sleeve. When the fabric tension is such that the loops are extended to the desired extent without the yarns being stretched, it causes lever 11 to move sufficiently to close a switch 12 while a second arm 21 of lever 11 depresses a pawl 20 to lock roller 9 against further forward rotation. Course counting. Closure of switch 12 starts an electric motor driving a crank shaft 39 which, through a crank pin 41 and slotted lever 42, reciprocates a casing 28 along a plate 26 beneath the fabric 10. A nipple 30 projecting from casing 28 cortacts the fabric and successive course ridges on the lower surface of the fabric enter a cross groove in the nipple face and depress a plunger 35, Fig. 7, each pulsation of plunger 35 breaking contacts 33, 34 in a circuit 63. The pulses in circuit 63 are used to operate a counting mechanism. A disc on shaft 39 has a conducting segment which, together with a cooperating brush, is placed in circuit 63 and operates to transmit pulses to the counting mechanism only when the casing is moving from left to right, Fig. 1. At each break in circuit 63, a solenoid 54, Fig. 8, is de-energized to allow a spring-loaded pawl 53 to advance a ratchet wheel 51 by an amount determined by an adjustable stop 56. Ratchet wheel 51 is mounted on a shaft 49 which also carries a pointer indicating the total count on a dial on the top of the casing 2, Fig. 1. During return movement of casing 28, a sector-shaped plate 59, Fig. 5, on shaft 39 engages a disc 60 on the pointer shaft 49 and rotates it until a flat 61 on the disc reaches the dotted line position when the pointer will have been zeroized ready for the next count.

摘要： Circular hosiery knitting machine produces a depending tube of connected hose, and below the knitting head is suspended a positioning tube into which the lower end of the hose tube is turned during continuous knitting, for eversion of the leading hose of the string. Specifically the hose is turned into the bottom of the positioning tube by air jet, and the tube has air escape holes, the air jet issuing from the innermost finger of a pair of gripper fingers which are movable away from the tube to separate the gripped leading hose from the string. Pref. the sepd. hose is dropped upon a collector board with a pusher which transfers the hose to a collection station with alternative stack boards controlled by a counter. No separate everting and sepg. machine is needed.

摘要： An apparatus and method is provided for turning, separating, stacking and counting hosiery directly on a knitting machine. A hosiery positioning tube is suspended below the knitting cylinder of the machine with the hosiery string being knitted around the tube. The tube is suspended on a hanger extending through a hollow star rod of the machine. Intermittently driven feed rollers are positioned on opposite sides of the tube to step feed the hose string down the tube. Gripping fingers mounted on a swinging arm just below the bottom of the tube separate each hose in turn. An air orifice on the inner finger positioned in the mouth of tube intermittently blows the final hose on the string up into the tube to provide an everting operation. As the end of the turned hose approaches the mouth of the tube where a ring of breakaway yarn is knitted, the intermittent air pulses are interrupted and a continuous jet of air from an orifice adjacent the outer gripping finger blows the end of the hose inwardly and downwardly to position the end of the hose firmly in the grip of the fingers. The fingers close and the arm pulls the turned hose to separate it from the string and deliver it with the aid of another jet pulse of air across the edge of a stacking board. A stripper/pusher moves along the edge of the board to transfer the hose to a stack as still another air jet pulse blows the end of the hose free of the fingers. A counter may be provided to count the hose with switchable board means providing two collecting stations, each having a groove in which a string is positioned for tying one dozen pair in a bundle.
