Filed:

Aug 25, 2003

Appl. No.:

10/648732

Inventors:

William Bryan - Yelm WA, US

International Classification:

B21D 7/02

US Classification:

72214, 72217, 72294, 723901, 723899, 72464

Abstract:

A portable devic for bending and cutting rebar, reinforcing rod, and the like. For cutting, a shaft assembly is movable along a first longitudinal axis (A—A) between a retracted and an extended position. A movable cutting head carried by the shaft assembly coacts with a fixed cutting head to shear rebar disposed between the cutting heads when the shaft assembly is moved to the extended position. For bending, a push rod movable along a second longitudinal axis (C—C) parallel to the first axis (A—A) couples movements of the shaft assembly through a clevis to a crankshaft such that longitudinal movements of the shaft assembly cause rotational movements of the crankshaft about an axis substantially perpendicular to axis (A—A). A first driven wheel, mounted for rotation with the crankshaft, has one or more bending blocks attached to the wheel by a radial arm. Rebar inserted in a gap between the first wheel and a second, idler wheel, is bent by the bending blocks as the wheels rotate in response to movement of the shaft assembly from a retracted to an extended position.

William Roy Bryan - Peoria AZ, US

International Classification:

B41F 1/07
B41F 17/00

US Classification:

101 5, 101 31, 101 4, 101 22, 101 36, 101375, 101480, 101485, 426338, 426665

Abstract:

Roll-forming apparatus is provided together with a conveyor system utilized to transport raw dough rolls. A stop gate is movably positioned in the path of the rolls and, when placed in an interfering position, temporarily stops the rolls while the rolls maintain sliding contact with the conveyor. An imprinter is positioned above the conveyor and adjacent the stop gate. The stop gate is subsequently moved to a noninterfering position to permit the rolls to pass to the imprinting drums where the rolls are formed into a desired shape.
