  • Patent number: 5090343
    Abstract: A chaining thread sew-in device for sewing a chaining thread produced consectively in the seams of a preceding cloth and in the seams of a next cloth when forming seams by an overlock sewing machine. The free end of the chaining thread (Ch) cut off from the preceding cloth is inserted into an insertion hole (H) opened on a sewing machine working face (1a), and the inserted chaining thread (Ch) is pinched beneath the sewing machine working face (1a), so that the chaining thread to be sewn into the seams of the next cloth is set at specified position on the sewing machine working face (1a). The chaining thread set at a specified position is moved to a cutter (40) installed side of the machine by driving a sub-pinching plate (72, 272), and is cut off from the pinched part by this cutter (40).

  • Patent number: 5070709
    Abstract: The striper of the system is provided with yarnguide rods which are pivotable to a position conducive to delivery of yarn to the needle. The rod to be pivoted is selected by a selector which imposes a small movement on a slide member and this small movement causes the slide member to be moved by a first radial cam such that its movement causes pivoting of the rod. Independently of said pivoting, a closing lever and an opening lever respectively adapted to retain and cut the yarn or release it are always moved. The movement of said levers, is only effective when at least one yarnguide rod has pivoted. There is a striper for each cam section and all of them are controlled by a single selection box containing the selectors.

  • Patent number: 5063756
    Abstract: In an elastic yarn feeding device of a multi-yarn feeding circular knitting machine, a rotary drive shaft (18) is horizontally arranged above a circular horizontally rotary plate (6), and the drive shaft (18) is provided with a drive roller (17) to be slidable in a longitudinal direction of the drive shaft. The drive roller (17) is urged against the upper surface of the rotary plate (6). When the rotary plate (6) is driven to rotate, the drive roller (17) is also rotated together with the rotary plate. Both the drive roller (17) and the drive shaft (18) are varied in rotational speed by moving the drive roller in the radial direction of the rotary plate (6). The drive shaft (18) has a plurality of feed rollers (21a, 21b, 21c, 21d) secured to it, and pinch rollers (26a, 26b, 26c, 26d) are elastically pressed against these feed rollers, respectively. Elastic yarn (Y) is fed through between each pair of the feed roller and the pinch roller.

  • Patent number: 5060488
    Abstract: The device comprises a plate placed over the needle beds and provided with two vertical grooves for each work zone. Within the grooves small bars slide vertically because of the action of a rocking lever that acts on the bars through two arms. The rocking lever has a third arm subject to the action of a rack, while a segment is hinged to each small bar and bears, fixed to its lower end, a small rod having a "L" shape, for pressing over the fabric. The rod extends for the whole length of the associated work zone. The grooves determine the contemporary oscillation of the small bars in opposite directions during their vertical movement, to allow the concurrent change of position of the small rods, while a wedge-shaped element, for retaining the fabric, is placed at the beginning and at the end of each work zone.

  • Patent number: 5046334
    Abstract: An upstanding knitting cylinder carries a multiplicity of needle jacks on its circumference. In order to selectively more the needle jacks up and down on the knitting cylinder during the rotation thereof, a vertical flow of selector fingers capable of engagement with butts on the needle jacks are rigidly mounted to respective sleeves which in turn are rotatably mounted on fixed horizontal shafts disposed in parallel spaced relation to one another in a vertical plane. Disposed opposite the respective sleeves on the fixed shafts are several pairs of electromagnet assemblies which are arranged in two diagonal rows in order to reduce the vertical dimension of the needle selector. An armature secured to each sleeve is held opposite each pair of electromagnet assemblies so as to be alternately attracted thereby, with the consequent bidirectional rotation of the sleeves and, therefore, the pivotal motion of the selector fingers to engage and disengage the needle jack butts.

  • Patent number: 5042274
    Abstract: A piezoelectric needle selector utilizes an upstanding knitting cylinder having a multiplicity of needle jacks mounted thereto for independent movement in a direction parallel to the axis of the knitting cylinder. A plurality of piezoelectric actuators, each having a stack of planar piezoelectric elements coupled at one end to a plunger, are mounted via respective holders to a fixed support frame disposed adjacent the knitting cylinder. The selective application of voltage pulses to the piezoelectric actuators results in the linear travel of the associated plungers toward and away from the knitting cylinder. The linear travel of the selected plungers is translated into the movement of the desired needle jacks up and down on the knitting cylinder, as by several needle select levers pivoted by the plungers and acting on the usual butts on the needle jacks.
