Patent number: 6598430Abstract: A compound needle (1) is provided with a slider (8) having two slider springs (11, 12). These are arched away from each other in a section immediately adjoining their insertion funnel (28). The compound needle has a slider slit (4), which initially is relatively narrow at its inlet (15), so that a guide section (4a) has been established there. Thereafter the slider slit (4) widens, so that a running section (4b) is established. The lateral bulge of the slider springs (11, 12) is of such a dimension that the slider (8) runs free in the running section (4b), and is guided without lateral play in the guide section (4a). The compound needle (1) also operates precisely in case of tension forces acting laterally on the slider (8) and requires only a small opening width of its funnel (28).Type: GrantFiled: June 21, 2002Date of Patent: July 29, 2003Assignees: Groz-Beckert KG, Shima Seiki Mfg., Ltd.Inventors: Klaus Ruoff, Norbert Gomeringer, Andreas Dietz

Patent number: 6591637Abstract: A closing device (4) is provided for closing a tube-shaped knit fabric on one end, for example for producing stockings or socks, which has plates (9) and counter-plates (13). The latter each have loop-carrying sections (18, 41), whose ends are designed to be complementary to each other and can engage each other in an interlocked manner. Here, the plates (9) have a receiving end, and the counter-plates (13) a penetrating end. The receiving end is constituted by a receiving funnel (28), formed by the ends of two legs (22, 23). These can be resiliently bent away from each other. This has the advantage that the penetrating counter-plate (13) cannot cause any damage to the plate (9) if it is moved too far in the direction toward the plate (9). There is the further advantage that in the course of the dipping movement of the needle into the free space of the plate, as well as during the relative movements between the needle and the plate, damages are almost impossible.Type: GrantFiled: October 17, 2002Date of Patent: July 15, 2003Assignee: Groz-Beckert KGInventor: Eric Jürgens

Patent number: 6564589Abstract: 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.Type: GrantFiled: March 21, 2002Date of Patent: May 20, 2003Assignee: Groz-Beckert KGInventor: Eckhard Fehrenbacher

Patent number: 6546761Abstract: A compound needle (1) is provided with a slider (8) having two slider springs (11, 12), whose ends constitute an open funnel pointing toward the hook (3). The ends, or legs (21, 22), constituting the funnel, are flattened. Therefore, starting at a starting point, the thickness of the material is reduced in the tapered area (29) toward the ends of the slider springs (11, 12). By means of this a correct functioning of the compound needle is also provided if the slider (8) is not completely centered. Moreover, it is possible to improve the easy movement of the slider (8) in the slider slit in that the funnel, formed by the legs (21, 22), can be embodied to be narrower at a constant width, than without the taper of the slider springs (11, 12).Type: GrantFiled: June 21, 2002Date of Patent: April 15, 2003Assignees: Groz-Beckert KG, Shima Seiki Mfg., Ltd.Inventors: Klaus Ruoff, Jürgen Schneider, Andreas Dietz

Patent number: 6510714Abstract: A latch needle (1) has a leaf spring (8, 8′) that is associated with the latch (4), that is disposed in the sawslot (3) and is held in corresponding bearing seats (14, 15) at the narrow sides or end walls (11, 12) defining the sawslot 3. Each bearing seat (14, 15) has a support surface (18) for the respective end of the spring, and at least one counterpart surface (21), with the respective end (16, 17) of the leaf spring (8) extending between these two surfaces and being held there. The axial or longitudinal play of the leaf spring (8, 8′) is so small that the leaf spring (8, 8′) cannot fall out of the space between the support surface (18) and the counterpart surface (21), even when it is deflected to a considerable extent. The leaf spring (8, 8′) is therefore held securely in the sawslot (3).Type: GrantFiled: June 7, 2002Date of Patent: January 28, 2003Assignee: Groz-Beckert KGInventor: Lothar Dehner

Patent number: 6339942Abstract: 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.Type: GrantFiled: October 18, 2000Date of Patent: January 22, 2002Assignees: Groz-Beckert KG, Shima Seiki Manufacturing Ltd.Inventors: Sigmar Majer, Bernhard Schuler, Kurt Wiedenhöfer, Toshiaki Morita, Kenji Kitahara
