  • Patent number: 6339942
    Abstract: A compound needle comprises a closing element with two closing element springs. These are designed to be asymmetrical relative to each other or at least provided with clearances or openings which, during the operation of the compound needle, are made to overlap with a corresponding cutout or other openings in the basic compound needle member, so that deposits can be removed to the needle channel. An asymmetric design of the closing element springs prevents the closing element from being wedged into the closing element channel, even if the deposit removal is incomplete. As a result, the compound needle wear is reduced considerably and the operational safety is increased.

  • Patent number: 6209360
    Abstract: A latch needle includes a head; a cheek having two facing side walls each having an inner wall face and an outer wall face; a sawslot defined by the inner wall faces of the side walls; and a pivot pin being formed at least on one of the side walls by plastically deforming the side wall. The pivot pin extends from the inner wall face of the side wall into the sawslot. The latch needle further has a first depression provided in the outer wall face of the side wall in alignment with the pivot pin. The first depression includes a bottom having a peripheral region in which a second depression is provided. A needle latch cooperates with the head and has a latch shank accommodated in the sawslot. The latch shank has a hole into which the pivot pin extends for forming a bearing support for the needle latch.

  • Patent number: 4747277
    Abstract: A latch needle for a textile machine including a latch displaceable in a longitudinal slot of a needle shank and pivotally mounted by means of a continuous bearing bore on two coaxial shaft stubs disposed at needle shank cheeks which laterally delimit the longitudinal slot. Each shaft stub projects into the longitudinal slot and comprises a separate cylindrical bolt which is inserted with a tight fit into a continuous bore in the associated needle shank cheek and is fixed therein so as to be secure against displacement.

  • 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.
