Abstract
An improved fabric cutting machine for cutting tubular fabric into strip form having simplified and manually controllable adjustment devices for selectively controlling the rate of withdrawal of the tubular fabric from its source, the desired width of the strip to be cut and for synchronizing the rate of rotation of the feed means for advancing the fabric to the cutting apparatus with the rate of rotation of that portion of the machine which supports the source of tubular fabric.
Claims3
A strip cutting machine of the type having a stationary frame with a support frame mounted thereon for rotation about the axis of the machine and for supporting a source of tubular fabric to be cut into strip form by a cutting apparatus carried on the stationary frame, said strip cutting machine comprising:
- a. feed means (24) connected to the stationary frame which includes a plurality of rotatably driven stretch and feed rollers (49) radially spaced from and extending substantially parallel to the axis of the machine;
- b. a first regulating means (59) operatively connected to said feed means for selectively inclining each of said stretch and feed rollers simultaneously relative to the axis of the machine to produce a withdrawing force on the tubular fabric and direct the same toward the cutting apparatus;
- c. means defining a second regulating means (66) connected to said feed means for varying the distance between said stretch and feed rollers (49) and the axis of the machine for maintaining a substantially cylindrical configuration of the fabric while it is being advanced to the cutting apparatus;
- and
- d. variable drive means operatively associated with said feed means for sychronizing the rate of rotation of said feed means (24) with the rate of rotation of the support frame.
