Abstract
An apparatus for cutting running workpiece includes a cutter for cutting, while the workpiece is running, the workpiece continuously supplied to run in a direction, and a travel member secured to the cutter, movable along the workpiece in contact with the workpiece. Since the travel member movable along the workpiece in contact with the workpiece is secured to the cutter, the cutter can follow a workpiece which is straight, curving or curving with a changing curvature. The cutter can be supported to be two-dimensionally movable to cut the workpiece in any form.
Claims4
An apparatus for cutting a workpiece while the workpiece is running, comprising:
- a cutter for cutting a workpiece;
- a travel member secured to the cutter and movable with the cutter along the workpiece while in contact with the workpiece, wherein the travel member includes a housing secured to the cutter and a rotary member rotatably supported by the housing and in contact with the workpiece;
- a rotary member drive apparatus connected to said rotary member so as to drive said rotary member to cause the housing to run along the workpiece;
- and
- a controller connected to said rotary member drive apparatus for driving said rotary member drive apparatus such that the rotary member drive apparatus stops the rotary member when the workpiece is being cut and, when the workpiece is not being cut, actuates the rotary member to rotate in a direction opposite to a running direction of the workpiece and with a higher speed than a running speed of the workpiece until the cutter returns to an initial position thereof, and in an opposite direction to the running direction of the workpiece with the same speed as the running speed of the workpiece when the cutter returns to an initial position thereof.

- a rotary member drive apparatus connected to said rotary member so as to drive said rotary member to cause the housing to run along the workpiece;
- and
- rotary member drive apparatus control means for causing the rotary member drive apparatus to stop the rotary member when the workpiece is being cut and, when the workpiece is not being cut, for causing the rotary member drive apparatus to actuate the rotary member to rotate in a direction opposite to a running direction of the workpiece and with a higher speed than a running speed of the workpiece until the cutter returns to an initial position thereof, and in an opposite direction to the running direction of the workpiece with the same speed as the running speed of the workpiece when the cutter returns to an initial position thereof.
