International ClassD04B 015/88Foreign Application Priority Data1987-05-01 JPAbstractA circular knitting machine comprising a knitting assembly for forming a tubular knitted fabric, fabric transport rollers for delivering the fabric from the assembly, a take-up spool for rolling up the delivered fabric thereon, and a pair of opposed frames stoppably rotatable about a vertical axis in synchronism with the knitting assembly. The rollers and the spool are supported by the frames. A constant torque is transmitted from a drive transmission for the frames to the transport rollers by a constant-torque transmission utilizing a magnetic force, while the spool is driven with power transmitted from the drive transmission through a belt transmission, so that the fabric knitted at a high speed can be rolled up properly. The spool comprises a pair of divided spool members and is therefore easily withdrawable from the rolled-up fabric. | |
