Abstract

A knitting machine having a plurality of latch needles on a latch needle holder rotatably supported on a machine plate on a machine truss, the latch needles being capable of performing a knitting operation when the latch needle holder is rotated by a driving device. The driving device has a gear member, wherein the gear member is disposed away from the latch needle holder so that the distance oscillation created by the gear member must travel for reaching the latch needles is lengthened, and/or an oscillation damping structure is further provided whereby the oscillation which would create undesirable horizontal lines upon the knitted fabric is counterpoised and thereby greatly reduced. The oscillation damping structure includes an oscillation damping plate having one end fixedly mounted on a hub formed on a first machine plate and another end fixedly supported by another machine truss. A second central hollow shaft is rotatably supported by a second machine plate. An upper latch needle plate is fixedly mounted to the second central hollow shaft and has a plurality of upper latch needles to cooperate with the latch needles on the latch needle holder. A plurality of cams are adapted to enable the upper latch needles to perform a knitting operation when the upper latch needle plate is rotated, and an upper damping plate has one end fixedly mounted on a hub formed on said second machine plate and another end fixedly supported by another machine truss. A synchronous driving means is provided for causing the upper latch needle plate to rotate synchronously with the latch needle holder, and a knife is provided in between the upper latch needle plate and the latch needle holder for cutting the knitted fabric. The combined central hollow shaft is provided with an opening formed between the upper latch needle plate and the latch needle holder, with the opening being adapted to allow the knitted fabric cut by the knife to flow into the hollow interior of the integrally combined central hollow shaft.
