Abstract
A device for cutting flat strips of desired width from relatively elongate material is described. Methods of using the strip cutting device are also described. Embodiments of the strip cutting device are adapted to readily cleave a leg from L-shaped material to produce flat strips. Some embodiments are adapted to precisely and accurately cleave flat strips of material to produce narrower flat strips.

A strip cutting device comprising:
- a mounting block, the mounting block including substantially rigid material;
- a cleaving apparatus, the cleaving apparatus including:
- a first cutting wheel, the first cutting wheel being adapted to rotate and comprising a first axis of rotation and a first cutting edge, the first cutting edge residing at a circumference of the first cutting wheel;
- a second cutting wheel, the second cutting wheel being coupled to the mounting block and being adapted to rotate relative to the mounting block, and the second cutting wheel including a second cutting edge, a second cutting wheel surface, and a second axis of rotation, the second cutting edge residing at a circumference of the second cutting wheel, the second cutting wheel surface being disposed on a plane that is substantially perpendicular to the second axis of rotation, and the second axis of rotation being substantially parallel with the first axis of rotation;
- a feed channel, the feed channel comprising a cavity residing between the second cutting wheel and the mounting block and being bounded on a first side by the second cutting wheel surface and bounded on an opposite side by the mounting block, and the feed channel being open at a front end and a back end, the front and back ends residing along a feed channel longitudinal axis and at opposite ends of the feed channel, the feed channel longitudinal axis being substantially parallel to the second cutting wheel surface, wherein the mounting block further comprises a planar wall surface, the planar wall surface (i) being substantially parallel with the second cutting wheel surface and (ii) being a portion of the mounting block that bounds the opposite side, and wherein the planar wall surface extends substantially parallel to and beyond the entire second cutting wheel surface to create the feed channel.
