  • Patent number: 4542601
    Abstract: A trousers ironing machine is provided with devices for automatically picking up trousers at the end of the ironing process and successively orderly gathering them. The machine comprises essentially a pair of side-by-side flat structures each including two portions of elongate shape which are arranged sequentially lengthwise. The two elongate portions can be moved toward and away from each other and jointly rotated through 180.degree. about an intermediate axis extending orthogonally to the plane of lay. Positioned above each flat structure is an ironing platen which is suitably set up to apply an appropriate pressure to the structure, a sliding gripper being arranged below the structure for gripping the ironed trousers and pulling them out of the structure.

  • Patent number: 4512270
    Abstract: A hemming guide control for an overlock sewing machine which assures stitching of portions of the fabric to be sewn just forward of and behind a cross seam. The apparatus includes a hemming guide unit having a fabric guide surface, which is movable laterally with respect to the direction of sewing, structure for detecting the cross seam longitudinally behind the fabric guide surface, and structure, responsive to the detection of the cross seam, for moving the hemming guide unit away from the fabric to be sewn just before the stepped cross seam crosses beneath the sewing needle, and returning the hemming guide unit to its original position after the cross seam passes under the sewing needle, thereby to eliminate excessive pressure on the cross seam by the fabric guide surface along a segment of the sewing path from just forward to just rearward of the cross seam.

  • Patent number: 4495879
    Abstract: Upper and lower fabric pieces are separated by a presser foot and sewn along a seam with respective edges left therealong. The upper and lower fabric pieces are fed along in a direction by means of a main feed dog. The edge of the upper fabric piece is folded back on the latter by means of a guide member disposed above a throat plate, with the guide member heated to heat the seam. The edge of the lower fabric piece is folded back on the latter below the throat plate by means of a guide rod mounted on the throat plate. The folded edge of the lower fabric piece is lifted up to the throat plate by means of an auxiliary feed dog, and guided onto a bearing plate by means of a guide body movable with the main feed dog. The upper and lower fabric pieces with their folded edges are pressed with heat between a roller and the bearing plate while being moved in said direction by the roller being rotated. Steam is applied against the seam when it is heated by the guide member.

  • Patent number: 4171629
    Abstract: A new latch box for stop motion apparatus for knitting machines of the type wherein the stop motion acts to automatically stop the machine when there is an undesirable amount of excess tension in the yarn being fed to the machine. The new latch box is of non-electrically conductive material and cooperates fully with the other parts of the apparatus as completely as the replaced latch box. A trigger is added to the new latch box in addition to its latch. Both the latch and the trigger are under the control of the yarn feeding arm of the apparatus in such manner that when there is excess yarn tension the trigger is actuated before the latch is actuated thereby to actuate the stop motion to stop the machine sooner than it would be stopped by the prior art latch boxes.

  • Patent number: 4147120
    Abstract: An auxiliary feed mechanism adapted for use with a sewing machine including a feed roller for advancing the workpiece through the work station and a mounting structure adapted to move the feed roller between two positions in one of which the feed roller is operative to aid in feeding the workpiece through the workstation and in the other of which the feed roller is rendered ineffective to transmit motive power to the workpiece. A plurality of flexible couplings drive the feed roller in timed relation to the actuation of a variable speed drive motor which is coupled in a unique electric circuit relationship with the main drive motor of the machine so as to vary the feeding rate of the feed roller in accordance with the machine cycle rate.

  • Patent number: 4096713
    Abstract: This knitting needle is a latch needle of the male latch-female hook type. The shape of the groove in the hook and the shape of the latch is such that during the initial use of the needle, only the end of the inner surface of the latch contacts the bottom surface of the groove. The amount of the surface of the inner portion of the latch which contacts the groove bottom surface gradually increases as the groove bottom surface and the inner surface of the latch are worn by use.

  • Patent number: 4064709
    Abstract: A wrap feeding device for a circular knitting machine comprising a support ring and a yarn guide mounted on the support ring and pivotally movable in a horizontal plane, the yarn guide having a front end extension extending outwardly from the support ring over the head of the vertical needle and forming a hole in its front end through which the yarn passes. A cylinder is disposed beneath the support ring concentrically therewith, and a return spring is connected with the yarn guide so as to normally retain the yarn guide in a position deflected toward a direction of rotation of the cylinder.

  • Patent number: 4043151
    Abstract: The present invention relates to a method of producing pile or plush goods or fabrics on circular knitting machines with plush hooks in the cylinder and latch needles in the dial and circular double knitting machines by means of pile hooks in a needle bed. Certain selected pile hooks are raised prior to the needles in order to prevent the fabric from raising with the needles while the pile hooks which are not selected for the formation of pile loops are retracted prior to the feeding of the pile yarn. Subsequent to the formation of the pile loops, the pile hooks are advanced into the loop forming position by the stitch cam until the needles move into an inactive position after the stitch formation, in order that the stitches are relieved (from tension) and withdrawn from the dial.

  • Patent number: 4043152
    Abstract: A method for producing double knit fabric of a given gauge (usually fine gauge) with an inlay of a coarser gauge yarn on a knitting machine with two needle beds. One side of the fabric is formed of only relatively fine gauge yarn and the relatively coarser inlay yarn is confined to the other or surface side of the fabric. Selected needles in one of the needle beds are replaced by drive elements. The inlay yarn is laid in by an inlay wheel driven in synchronization with the needle bed by said drive elements.

  • Patent number: 4043518
    Abstract: Yarn from a rotatable package of the type comprising a cylindrical support upon which the yarn is packaged by winding, is fed in a precise and certain manner to a source of utilization of the yarn. A drive roll is positioned in proximity to, but spaced from the yarn package, and is mounted for rotation about its longitudinal axis, the longitudinal axis of the drive roll being substantially parallel to the longitudinal axis of the yarn package. A resilient circular band having an annular cross-section is stretched over the package and the drive roll so that the band is urged against the exterior surface of both. A means is provided for driving the drive roll at a rotational velocity corresponding to the rate of consumption of the yarn, and guide means directs the yarn to the source of its utilization.
