<p>In a tool for cutting film or cardboard, it is known that a guillotine or industrial razor blade has been established as the method of cutting, and that mechanisms without power are marketed for manual steel rule cutting on top of the artwork. In this invention, the severing action of a 2000 r.p.m. motor driven circular razor, and the perfectly straight guidance of a fluorocarbon bearing carriage across a rigid transverse T-bar set at a maintained height above a table platform, makes heavy cuts without twisting or skewing and without clamping. The design incorporates a slide that lifts and lowers to manipulate the inside bevelling of matboard. Interchangeable with the razor arbor is a small diameter fine tooth saw arbor with an attachment for smooth cutting on thin paper. The motor switch is a press on, hold, and release stop action entirely favourable to the concept of non-clamping.</p> |
