Abstract
Abstract A knitted fabric draw-off and take-up arrangement for circular knitting machines, including an idle take-up roller and at least one driven draw-off roller. The tubular knitted fabric is passed from the draw-off roller to the take-up roller and is then returned to the draw-off roller after passing around the take-up roller and finally is returned and secured to the take-up roller thereby the tubular knitted fabric is wound onto the take-up roller and also drives this idle take-up roller.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
A knitted fabric draw-off and take-up arrangement for circular knitting machines, comprising in combination, a support structure; an idle take-up roller rotatably mounted in said support structure; at least one draw-off roller rotatably mounted in said support structure, the axes of said take-up roller and draw-off roller being parallel; driving means operatively connected to said draw-off roller for drivingly rotating the latter; said arrangement being adapted to withdraw tubular knitted fabric from a circular knitting machine and to guide it as least partially around the draw-off roller and then at least partially around the take-up roller and then again at least partially around the draw-off roller and then is wound on the take-up roller, so that the tubular knitted fabric drives the idle take-up roller.
Claim 2
Dependent Claim
125 words
A knitted fabric draw-off and take-up arrangement for circular knitting machines, comprising in combination, a support structure; an idle take-up roller rotatably mounted in said support structure; at least one draw-off roller rotatably mounted in said support structure, the axes of said take-up roller and draw-off roller being parallel; driving means operatively connected to said draw-off roller for drivingly rotating the latter; said arrangement being adapted to withdraw tubular knitted fabric from a circular knitting machine and to guide it as least partially around the draw-off roller and then at least partially around the take-up roller and then again at least partially around the draw-off roller and then is wound on the take-up roller, so that the tubular knitted fabric drives the idle take-up roller.
Claim 3
Dependent Claim
103 words
The knitted fabric draw-off and take-up arrangement for circular knitting machines as set forth in claim 1, wherein at least two draw-off rollers and a guide roller are rotatably mounted in said support structure, said draw-off rollers are biased against each other and the draw-off and guide rollers have parallel axes; whereby said tubular knitted fabric is guided between said two draw-off rollers and at least partially around said guide roller and then at least partially around said take-up roller and finally at least partially around one of the draw-off rollers or the guide roller and then is wound on the take-up roller.
Claim 4
Dependent Claim
53 words
The knitted fabric draw-off and take-up arrangement for circular knitting machines as set forth in claim 2, wherein three draw-off rollers are rotatably mounted in said support structure parallelly relative to each other, the two outer draw-off rollers are resiliently biased against the middle draw-off roller, the latter operating as a guide roller.
