  • Patent number: 4691535
    Abstract: A yarn-selecting device of a knitting frame comprises a mechanism for joig the yarn being knitted to a selected yarn to be knitted, which mechanism comprises a swivelling finger for forming a closed loop of the yarn to be knitted. Two levers form an open loop of the yarn being knitted and insert it through the closed loop of the yarn to be knitted on the finger. A hooking lever is provided for pulling the yarn to be knitted through the open loop of the yarn being knitted, after which the open loop-forming lever is retracted thus removing the closed loop from the finger, and the yarn being knitted is cut by a knife while the end of the yarn to be knitted is released from a gripper.

  • Patent number: 4632324
    Abstract: A simplified strand storage and feeding device having a rotatable spool about which a traveling yarn is transiently wound while being fed to a textile machine, utilizes a noval driving arrangement for rotation of the spool, including a pulley operatively affixed to the spool and having plural radial teeth circumferentially spaced about one side of a belt receiving recess in the pulley and a driving belt having compatible edge notches meshing with the pulley teeth. The edge notched configuration of the belt provides positively timed driving of the device while also being spliceable by mechanical interconnection of separate belt ends, so that the belt may be of non-endless form for ease of installation and breaks therein may be easily repaired by splicing. A slidably movable yarn withdrawal guide eyelet is provided for withdrawing yarn from the spool either tangentially or generally axially therefrom for operation of the device in either a positive or demand feeding mode.

  • Patent number: 4089279
    Abstract: An improved technique for automatically producing a reinforced, peripherally contoured fabric blank adapted to be folded over and sewn to form a finished panty is described. A plurality of fabric segments to the central portion of which an underlying reinforcing strip is sewn is advanced along a conveyor and into a first one of a plurality of work stations distributed around a turret that is rotatably carried on a fixed support. A plurality of magnetically-actuable fabric holders are rotatably supported on the outer ends of corresponding spider arms that extend toward the work stations from the turret. Each holder has a contoured periphery corresponding to that of the panty blank, and after receiving the fabric segment from the conveyor indexes it successively into a plurality of second work stations each equipped with a contour sewing machine.

  • Patent number: 4073319
    Abstract: Each shuttle of a multiple-shuttle weaving machine is provided with at least one shuttle magnet. A drive unit acts upon each shuttle magnet to effect positive magnetic transport of the shuttle through the length of the shed, without physically contacting the shuttle. The shuttle monitoring device includes a magnetic-field-dependent resistor for each shuttle to be monitored. The magnetic-field-dependent resistor is moved in parallel to and in synchronism with the drive unit for the shuttle and moves in a region where the resistor is influenced by at least one pole of the shuttle magnet. A machine shut-off device is connected to the resistor and is operative for shutting off the drive units for the shuttles of the weaving machine in response to a resistance change of the magnetic-field-dependent resistor indicative of lack of proper shuttle movement.

  • Patent number: 4066105
    Abstract: A loom having harnesses carrying an array of warp yarns defining a warp direction and displaceable in a shed direction transverse to this warp direction to form a main shed adapted to receive a weft passed through the shed in a weft direction transverse to the warp and shed directions has a leno selvage device. This device comprises at least one ground heddle at an edge of the array of warp yarns which carries a ground warp yarn. There is also provided a doup heddle at this edge which carries a doup warp yarn. One of these heddles is displaced synchronously toward the other heddle with the harnesses of the loom to form an edge shed in line with the main shed. A support is provided which defines a rocking axis nondisplaceable in the weft direction and a rocker is pivotal on the support about this axis between a pair of end positions. The doup heddle is operatively engageable with this rocker and can be deflected thereby in the weft direction to either side of the ground heddle.

  • Patent number: 4023383
    Abstract: A knitting machine has a housing on which is displaceable a support cylinder carrying an array of parallel needle holders displaceable up and down. Two armed levers are pivoted on each of the holders and each have a forked arm formed with an actuating foot and with an anchor foot spaced by a gap from the actuating foot, and another arm that is engaged by a spring carried on the holder that normally tries to bias the lever to move from an operative position into an inoperative position. A slide cam on the housing has lobes or formations which are engageable with the actuating feet of the levers to displace the holders and engageable between the feet of the lever so as not to displace the holders. Furthermore, a tip cam is provided on the housing engageable with the other arm of each of the levers to displace it into the operative position.

  • Patent number: 3981159
    Abstract: In a patterning arrangement for textile machines and the like, particularly for circular knitting machines, of the type wherein pattern pegs are inserted into peg-receiving holes in a pattern peg carrier provided with spaced rows of such peg-receiving holes, the following is provided, in combination: a holding arrangement operative for holding a pattern peg carrier of the type provided with spaced rows of peg-receiving holes, peg transport structure repeatedly moving back and forth between a first location and a second location, a peg feeding device activatable for feeding pegs into the peg transport structure when the peg transport structure is at the first location, a peg inserting device operative for inserting pegs into peg-receiving holes of the peg carrier whenever pegs are brought by the peg transport structure to the second location, and a control arrangement operable for controlling whether or not pegs are fed by the feeding device into the peg transport structure when the peg transport structure mov

  • Patent number: 3961501
    Abstract: The knitting machine includes a carrier, and a plurality of knitting-needle units, each comprised of a needle portion and a motion-transmitting portion mounted on the carrier for longitudinal reciprocation and movable between an operative position and a non-operative position. A motion-imparting arrangement, for example comprised of lifting and lowering cams, impats longitudinal motion to those of the motion-transmitting portions which are in the operative position. A selecting arrangement selects the positions of the motion-transmitting portions. The selecting arrangement includes a selecting cam arrangement which is movable between a first position in which the selecting cam arrangement engages the motion-transmitting portions and moves the latter to one of the positions thereof and a second position in which the selecting cam arrangement is not operative for so moving the motion-transmitting portions.

  • Patent number: 3934083
    Abstract: Method and apparatus for processing the information content of a pattern drawing in coded form for application to an utilization facility such as a storage device for controlling textile machines. The pattern drawing is scanned line-by-line and point-by-point and the scanned points are projected in enlarged form so that the information content of the scanned points is comprehended by an operator who registers its, by pressing a corresponding information key, first of all in an intermediate storage device of limited capacity, the content of whose stages is made visible in corresponding adjacent fields in an optical indication device. The information of the intermediate storage device is transferred in groups to the storage device as soon as the intermediate storage is filled up.
