  • 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: 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.
