Abstract
A circular knitting machine for the production of an opened fabric tube comprises a needle cylinder (1), a frame (6), which is coupled to the needle cylinder (1) and in which at least a draw-off roller (4) and/or a take-up roller (5), drive means (36 to 43) to drive said roller, and a blade (19) intended for opening the fabric tube are each rotatably mounted, and a flexible shaft (21), which is rigidly connected to the blade (19) and a drive wheel (38), for setting the blade (19) in rotation at a rotational speed dependent on the knitting speed. According to the invention, the drive wheel (38) of the flexible shaft (21) is functionally connected (FIG. 2) to the drive means (36 to 43) for the draw-off and/or take-up roller (4, 5).
Claims6
Circular knitting machine for the production of an opened fabric tube, comprising:
- a needle cylinder (1), a frame (6) in which at least a draw-off roller (4) and/or a take-up roller (5), drive means (28 to 34;
- 36 to 43) to drive said draw-off roller and/or take-up roller and a blade (19) for opening the fabric tube by cutting are each rotatably mounted, and a flexible shaft (21), which is rigidly connected to said blade (19) and a drive wheel (38), for setting said blade (19) in rotation at a rotational speed dependent on a knitting speed, wherein said drive wheel (38) of said flexible shaft (21) is directly connected to said drive means (28 to 34;
- 36 to 43) for said draw-off and/or take-up roller (4, 5) without being directly connected to and controlled by said draw-off and/or take-up roller (4, 5).
