Appl. No.:

11/749438

Inventors:

Timothy J. Roush - Flint MI, US
Michael C. Clark - Columbiaville MI, US

Assignee:

Tapco International Corporation - Wixom MI

International Classification:

B21D 7/02

US Classification:

72214, 72211

Abstract:

A portable hand tool includes a frame for guiding a sheet of material, e. g. , sheet metal. A pair of shafts are spaced from each other and are selectively slideable relative to the frame to define a plurality of adjustment positions. A pair of rollers are respectively mounted to the shafts for deforming the sheet of material between the rollers. An adjustment rod is mounted to and extends outwardly from the frame. A support interconnects the shafts and an adjustment device is rotatably engaged with the support. A coupling device is disposed about the adjustment rod and is moveable between an engaged position and a disengaged position. In the engaged position, the coupling device couples the adjustment rod and the adjustment device to lock the shafts and rollers laterally relative to the frame. In the disengaged position, the shafts and rollers are slideable relative to the frame between the adjustment positions.

Abstract:

A method of forming a polymeric building product having a color variation simulating natural building material includes introducing base color pellets having a base color into the barrel and providing a plurality of first colorant shots and second colorant shots. The first and second colorant shots are repeatedly introduced to the base color pellets in an alternating pattern. By repeatedly introducing at least one first colorant shot and at least one second colorant shot to the base color pellets in an alternating pattern, the barrel is in a constant state of purging. As one melted colorant shot is purged and replaced by another melted colorant shot, the melted composition includes streaks in the shape of swirls, wisps, etc., which advantageously creates color variations that simulate natural building material.
