Apparatus for severing a workpiece

摘要

An apparatus for severing a workpiece having a cutting mechanism operable to cut the workpiece substantially along a selected course; drive mechanism operable to drive the cutting mechanism to cut the workpiece; a transport assembly operable to guide the workpiece in movement relative to a predetermined severing position and with respect to the cutting mechanism; and a frame mounting the cutting mechanism and transport assembly in predetermined relation to each other and relative to the severing position so that the drive mechanism is operable to drive the cutting mechanism to cut the workpiece in the severing position.

1. An apparatus for severing a workpiece of a strong and resistant composition, the apparatus comprising:
a cutting mechanism having a severing blade operable to cut the workpiece substantially along a selected course at a severing position; a drive operable to drive the cutting mechanism to cut the workpiece; a transport assembly operable to guide the workpiece in movement relative to said severing position and with respect to the cutting mechanism; a frame mounting the cutting mechanism and the transport assembly in predetermined relation to each other and relative to said severing position whereby the drive is operable to drive the cutting mechanism to cut the workpiece in the severing position; a slotted rotational member mounted directly below the severing blade has a substantially U-shaped slot extending substantially circumferentially about the slotted rotational member and positioned to receive the periphery of the severing blade, and wherein the periphery of the severing blade forms a tapered peripheral cutting edge terminating at a point spaced from the bottom of the substantially U-shaped slot.
