摘要： A fabric take-up unit (5) is supported beneath the needle cylinder (4a) to rotate synchronously therewith and knitted fabric delivery rolls (11, 12, 13) are supported on the fabric take-up unit (5). The fabric delivery rolls (11, 12, 13) are normally driven in response to rotation of the take-up unit (5). In contrast to this normal drive, the knitted fabric delivery rolls (11, 12, 13) are driven by a planetary gear system including a sun gear (17) supported for rotation on the machine frame, a planet gear (18) meshing with the sun gear (17) and being supported on the take-up unit (5). The planet gear (18) is drivingly connected to the fabric delivery rolls (11, 12, 13). A drive motor (34) is fixed on the machine frame and is drivingly connected to the sun gear (17), and a control unit (50) is provided for controlling the speed of rotation of the drive motor (34) and the sun gear (17) so that the quantity of the knitted fabric taken up by the knitted fabric delivery rolls (11, 12, 13) is selectively varied by the speed of rotation of the drive motor (34) and the sun gear (17).
