Abstract

A rotary cutting apparatus includes a frame movable in a first direction and a second direction that is opposite the first direction. The apparatus includes a cutting roll. The cutting roll is rotatably connected with the frame and configured to rotate about a first longitudinal axis. The apparatus includes an anvil roll. The anvil roll is rotatably connected with the frame and is configured to rotate about a second longitudinal axis. The first longitudinal axis is substantially parallel with the second longitudinal axis. The apparatus includes a first stationary member adapted to prevent movement of the frame in the first direction. The apparatus also includes a second stationary member connected with the frame. The second stationary member has a first configuration that prevents movement of the frame in the second direction. The second stationary member has a second configuration that allows movement of the frame in the second direction.

First claim

What is claimed is:

1. A rotary cutting apparatus comprising:
a frame movable in a first direction and a second direction, wherein the first direction is opposite the second direction, wherein the first direction and the second direction are horizontal;
a cutting roll defining a first longitudinal axis, wherein the cutting roll is rotatably connected with the frame and configured to rotate about the first longitudinal axis;
an anvil roll defining a second longitudinal axis, wherein the anvil roll is rotatably connected with the frame and configured to rotate about the second longitudinal axis, the anvil roll positioned relative to the cutting roll such that the first longitudinal axis is substantially parallel with the second longitudinal axis;
a first blocking member adapted to prevent movement of the frame in the first direction, wherein the first blocking member is configured to engage a portion of the frame;
a second blocking member connected with the frame, the second blocking member comprising a base, a first arm connected with the base, a reciprocating member comprising a first end portion pivotally connected to the first arm and a second end portion pivotally connected to a second arm, wherein the second blocking member comprises first and second configurations, wherein the second blocking member is adapted to prevent movement of the frame in the second direction in the first configuration, and wherein the second blocking member is adapted to allow movement of the frame in the second direction in the second configuration while the cutting roll rotates;
a third blocking member positioned adjacent the first blocking member, wherein the third blocking member comprises a stop aperture; and
a sensor adapted to detect a defective operating configuration and upon sensing the same causing movement of the frame in the second direction.

2. The rotary cutting apparatus of claim 1 , wherein the first longitudinal axis and the second longitudinal axis are orthogonal to the first and second directions.

3. The rotary cutting apparatus of claim 1 , wherein in the first configuration, the second blocking member is adapted to apply a positive force to the frame in the first direction.

4. The rotary cutting apparatus of claim 1 , further comprising a track, wherein the frame is slideably connected with the track.

5. The rotary cutting apparatus of claim 1 , wherein the first blocking member is selectively positionable along the first and second directions.

6. The rotary cutting apparatus of claim 1 , wherein the second blocking member is selectively positionable along the first and second directions.

7. The rotary cutting apparatus of claim 1 , comprising a fourth blocking member positioned adjacent the second blocking member, wherein the fourth blocking member is engageable with a second stop pin.

8. The rotary cutting apparatus of claim 1 , comprising a joining member removably connected to the second arm and a portion of the frame.

9. A rotary cutting apparatus having a first mode of operation and a second mode of operation, the rotary cutting apparatus comprising:
a track having a first side and a second side opposite the first side, wherein the first side and the second side extend in a direction parallel to a machine direction;
a frame movable in a first direction and a second direction, wherein the first direction is opposite the second direction, wherein the first direction and the second direction are parallel to the machine direction, wherein the frame comprises a first portion extending between the first side of the track and the second side of the track and a second portion extending between the first side of the track and the second side of the track;
a cutting roll rotatably connected with the frame;
an anvil roll rotatably connected with the frame;
a first blocking member located adjacent to the frame and configured to engage the first portion of the frame;
a second blocking member removeably connected with the second portion of the frame, the secondary blocking member comprising:
a base;
a first arm pivotally connected with the base;
a reciprocating member comprising a first end portion connected to the first arm and a second end portion opposite the first end portion;
a second arm pivotally connected to the second end portion of the reciprocating member; and
a joining member connected to the second arm and a portion of the frame; and

a sensor adapted to detect a defective operating configuration and upon sensing the same causing movement of the frame in the second direction,
wherein in the first mode of operation, the first blocking member prevents movement of the frame in the first direction and the second blocking member prevents movement of the frame in the second direction,
wherein in the second mode of operation, the second blocking member allows movement of the frame in the second direction while the cutting roll rotates.

10. The rotary cutting apparatus of claim 9 , wherein the frame is moveably connected with the track.

11. The rotary cutting apparatus of claim 9 , wherein a transfer apparatus is located adjacent the cutting roll, and wherein a gap is formed between the transfer apparatus and the cutting roll.

12. The rotary cutting apparatus of claim 9 , wherein a transfer apparatus is located adjacent the cutting roll, and wherein a gap is formed between the transfer apparatus and the cutting roll.

13. The rotary cutting apparatus of claim 9 , comprising a third blocking member positioned adjacent the first blocking member, wherein the third blocking member is engageable with a first stop pin.

14. The rotary cutting apparatus of claim 13 , comprising a fourth blocking member positioned adjacent the second blocking member, wherein the fourth blocking member is engageable with a second stop pin.

15. A rotary cutting apparatus comprising:
a frame movable in a first direction and a second direction, wherein the first direction is opposite the second direction;
a cutting roll defining a first longitudinal axis, wherein the cutting roll is rotatably connected with the frame and configured to rotate about the first longitudinal axis;
an anvil roll defining a second longitudinal axis, wherein the anvil roll is rotatably connected with the frame and configured to rotate about the second longitudinal axis, the anvil roll positioned relative to the cutting roll such that the first longitudinal axis is substantially parallel with the second longitudinal axis;
a first blocking member adapted to prevent movement of the frame in the first direction, wherein the first blocking member is configured to engage a portion of the frame; and
a second blocking member removably connected with the frame, the second blocking member comprising a base, a first arm connected with the base, a reciprocating member comprising a first end portion connected to the first arm and a second end portion connected to a second arm, wherein the second blocking member comprises first and second configurations, wherein the second blocking member is adapted to prevent movement of the frame in the second direction in the first configuration, wherein the second blocking member is adapted to allow movement of the frame in the second direction in the second configuration, and wherein the cutting roll is configured to rotate while the frame is moved in the second direction;
a third blocking member positioned adjacent the first blocking member, the third blocking member including a first stop aperture;
a fourth blocking member positioned adjacent the second blocking member, the fourth blocking member including a second stop ap
