  • Patent number: 5609045
    Abstract: A knitting needle includes a shank, a needle hook carried by the shank at one end thereof, and a sawslot provided in the shank. The sawslot is bordered by elastically deformable shank cheeks which are provided by upper supporting surfaces. The sawslot has a throughgoing aperture which is open toward the shank back. A latch rivet traverses the sawslot and is supported in the shank cheeks. A needle latch having a latch back provided with engagement faces is pivotally supported by the latch rivet for swinging motions between a closed position in which the needle latch engages the needle hook and an open position in which the engagement faces on the latch back lie on the supporting surfaces of the shank cheeks. The sawslot has, in a series as viewed from needle hook, a first sawslot portion containing the throughgoing aperture and a second sawslot portion having a width greater than the width of the first sawslot portion.

  • Patent number: 5333208
    Abstract: For controlling the quality of the needles of a knitting machine a test image of each needle is acquired with the aid of an image sensor when the needle is moved out of its rest position for forming a stitch. The analog image signals obtained on reading out the image sensor are converted to digital pixel signals, and the digital pixel signals of the test image or of individual test zones of the test image are processed for recovering information on the state of the particular needle being imaged. By using a coarse resolution image sensor it is possible to detect major faults during the normal operation of the knitting machine at full working speed. Needles exhibiting wear and minor faults can be detected by using a high resolution image sensor during special inspection times in which the knitting machine is operated at reduced speed.

  • Patent number: 5076074
    Abstract: A knitting tool, such as a selector sinker or a needle for a knitting machine, includes a flat shank and a narrow elongate control spring projecting from a slot-like opening in a narrow side of the shank. One end of the control spring has a broader anchorage section at one end which is inserted into a recess provided at an inward end of the opening in the shank. The width of the recess, measured transversely to the longitudinal extent of the opening, is greater, at least at certain locations, than the width of the opening. The thickness of the anchorage section of the control spring is less than or equal to the depth of the recess. As a result, the control spring is rigidly anchored in the shank in a manner secure against rotation.

  • Patent number: 4905364
    Abstract: A method for producing the latch bearing in a latch needle for textile machines of the type in which a latch is pivotably mounted in a longitudinal slot between two cheeks of a needle shank by a hinge pin passing through mutually aligned transversely extending bores in at least one of the cheeks and a bearing portion of the latch between the cheeks. In accordance with the method a cylindrical wire is provided with transversely extending notches at intervals corresponding to the length of a hinge pin. The notched wire is converted by hot or cold treatment into a bittle, hard state. Individual hinge pins are broken off from the wire at the notches, and are subsequently inserted into the bores in the cheeks and the bearing portion of the latch to be securely fixed there.

  • Patent number: 4584852
    Abstract: A compound needle for a knitting machine has a machine shank of substantially rectangular cross section, in which a substantially U-shaped longitudinal groove open at the top is formed. A closing slider adapted to fit the cross section of the groove is guided in the groove in a longitudinally slidable manner, and the groove has at least one slit leading to the outside, which extends parallel to the longitudinal axis of the groove.In order to attain satisfactory removal of fluff or lint from the longitudinal groove, on the one hand, and to assure sufficient stability and resistance to transverse bending of the needle on the other, the longitudinal groove is closed on its top, at least partially, in the vicinity of the recess by means of a rib which also forms a guide for the slider.

  • Patent number: 4562705
    Abstract: To provide for damping of vibrations or oscillations exerted on the shaft or shank (7) of a knitting element, and thus reduce breakage of the shaft or shank and failure of the head portion thereof, the shaft or shank is formed with solid guide portions (10) of which at least one is in alignment with a butt extending from the shaft or shank. Two solid guide portions are connected by at least one connecting bridge portion (12) of only up to 1.1 mm height, and which defines an opening (11, 11a, 11b) therebeneath, with respect to the remaining edges of the shaft, which opening is filled with vibration or oscillation-damping material, such as a plastic or a metal, flush, or slightly recessed with the side surfaces of the shaft, and securely bonded to the edges of the adjacent bridge portion and the spaced solid guide portions facing the opening. The guide portions may be of different longitudinal dimension, for example have a dimension of only of that in the order of the bridge portion.
