Abstract: An oscillation damping and counterpoising circular knitting machine having a base, a machine truss fixedly mounted on the base, and a first machine plate fixedly mounted on the generally middle portion of the machine truss. A latch needle holder rotatably supported by the first machine plate has a circumference on which a plurality of latch needles are provided. A plurality of cams are disposed around the latch needles for effecting a knitting operation when the latch needle holder is rotated. Driving structure causes the latch needle holder to rotate, the driving structure including a first bracket member and a second bracket member with the first bracket member being operatively connected to the second bracket member by pin members having one end fixed on the first bracket member and another end loosely inserted into a slot formed on the second bracket member to allow self-alignment of the first bracket member with the second bracket member.

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.
