US Patent:

41080343, Aug 22, 1978

Filed:

Jun 13, 1977

Appl. No.:

5/806106

Inventors:

Anthony Vincent Thomas - Prospect Heights IL

Assignee:

Precision Paper Tube Company - Wheeling IL

International Classification:

B26D 316

US Classification:

83361

Abstract:

Tubes made from spirally wound paper tape are fed axially and suspended off the end of an arbor. When the tube reaches a predetermined length, the free end engages a free-hanging sensor plate, the movement of which interrupts a light beam to generate a signal which actuates a timer. The timer energizes a motor for a predetermined time to cycle a snap cutter through one circular orbit to sever the tube. The cutter is stopped at its original position by a brake.

Abstract:

The apparatus includes a cradle for holding long tubes desired to be cut into individual tubes of shorter length. The cradle is generally cylindrical and mounted for rotation about its axis. Tubes are mounted in the cradle at a loading position, and a controller actuates a motor for driving the cradle inrotation to a cutting position. A plurality of saws are mounted on a shaft extending parallel with the axis of the cradle and rotating at high cutting speed. When the cradle is revolved to bring the tube to the cutting station, the tube is engaged by a surface belt drive to spin the tube in the cradle for cutting. In the case of tubes having greater wall thickness, the cradle is stopped momentarily just as the tubes are brought into cutting relation with the saws so that a partial peripheral cut is made while the cradle is stopped. The cradle is then continued to be rotated to complete the cut and to bring the cut tubes back to the original position at high speed.
