  • Publication number: 20020134115
    Abstract: The latch needle according to the invention is provided with a latch slot with profiled inside areas of the cheeks. A latch is positioned inside this latch slot, for example with the aid of a rivet. The inside areas of the cheeks that immediately surround the rivet guide the latch on the side and together with the latch define a small play, thus resulting in a precise positioning. The remaining latch slot area can be wider to reduce the latch friction at the latch slot as much as possible.

  • Patent number: 5956976
    Abstract: A latch needle for loop-forming textile machines includes a needle shank having an upper side, a back and a sawslot extending into the needle shank from the upper side and oriented parallel to the shank. A hook is provided at an end of the needle shank. A spring element is disposed in the sawslot and has at least one end supported by the needle shank. A needle latch is supported in the sawslot for pivotal motion about an axis between a closed position in which the needle latch engages, with a frontal end thereof, the hook and a rearward position. The needle latch has a latch shank which includes an upper side and a lower side. In the rearward position the needle latch lies, with the upper side of the latch shank, on the upper side of the needle shank or is situated in the vicinity of the upper side of the needle shank. The latch shank further has an end part formed as a cam engaged by the spring element.

  • Patent number: 5488840
    Abstract: A latch needle for a textile machine includes a needle shank having a sawslot defined in the needle shank by two facing cheeks forming part of the needle shank; a pivot pin supported by the cheeks and extending transversely to the length dimension of the needle shank; and a latch accommodated in the sawslot. The latch includes a latch shank having an upper side and an opposite lower side. There is further provided a bearing bore in the latch shank. The bearing bore is traversed by the pivot pin to provide for a pivotal movement of the latch relative to the needle shank. The bearing bore is spaced from the upper side at a first distance and from the lower side at a second distance; the first and second distances have unlike lengths.

  • Patent number: 5239844
    Abstract: A latch needle for a loop-forming textile machine includes a needle shank; a sawslot provided in the needle shank and being defined by two parallel-extending needle shank cheeks; a rivet traversing the sawslot and being rotatably supported in the needle shank; a needle latch pivotally disposed in the sawslot and having a latch spoon and a rivet-receiving bore; and an elongated spring element having a first end anchored in the needle shank and a second end extending into the sawslot. In the closed position of the needle latch the second end of the spring element is in a pressing engagement with a support surface of the needle latch and resiliently urging the needle latch into an intermediate opening position. The needle latch has an open-ended recess extending from an end of the needle latch remote from the latch spoon into the rivet-receiving bore. The needle latch has a wall face defining the open-ended recess at one side thereof and carrying the support surface.

  • Patent number: 4817398
    Abstract: A latch needle for loop forming textile machines includes a steel needle shank and a nonmetallic latch. The steel needle shank has upper and lower edges, a sawslot defined in the needle shank and a needle hook at one end of the needle shank. The needle also includes an axle which extends transversely across the sawslot and contacts the needle shank. The latch is pivotally mounted on the axle and is provided with a noucat at one end. The latch is pivotal between an open and a closed position. When the latch is in the closed position, the noucat rests on the needle hook and when the latch is in the open position, the back surface of the latch contacts part of the needle shank. The nonmetallic material which the latch is composed of is a fiber reinforced thermoplastic homopolymer or copolymer plastic.

  • Patent number: 4781040
    Abstract: Disclosed is a latch needle for knitting machine to be readily assembled from a latch having a pair of transversely protruded pivots and plastically formed from a synthetic resin, as well as an extended needle body consisting of a shank portion. A hook portion is formed at one end thereof and a butt portion at the other end, in which said shank portion has a slot defined by opposite side walls, each having a hole for engagement with each of said pivots. A pair of slanted bottom walls receive said latch for angular movement, which is also plastically formed from the synthetic resin. Owing to slanted face formed on said pivots or said side walls, the latch may be pushed or stricken down in the slot with resiliently spreading the side walls.

  • Patent number: 4723425
    Abstract: A latch needle for a textile machine. The latch needle has a latch which is displaceable in a longitudinal slot of a needle shank and is pivotally mounted by means of a continuous bearing bore on a one-piece, cylindrical shaft bolt which is inserted into corresponding coaxial bores of needle shank cheeks on either side of the longitudinal slot and is fixed therein so as to be secure against displacement. The length of the shaft bolt is less than the thickness of the needle shank along the pivot axis. The outwardly oriented, free frontal faces of the shaft bolt lie in the depth of the bores of the needle shank cheeks. Fixing elements for the shaft bolt are shaped of the material of the needle shank cheeks in the vicinity of the free frontal faces of the shaft bolt.
