US Patent:

6857350, Feb 22, 2005

Filed:

Jul 22, 1999

Appl. No.:

09/358666

Inventors:

Kalin Liefer - Red Bud IL, US
Elroy Schoenbeck - Red Bud IL, US

Assignee:

Red Bud Industries, Inc. - Red Bud IL

International Classification:

B26D003/00
B21B001/00

US Classification:

83872, 83156, 834253, 72203

Abstract:

A machine for slitting metal sheet with rotating knives has roller assemblies which present rollers against the metal sheet immediately beyond the knives. The rollers bear against both faces of the slit metal sheet and straddle the slits, all to reduce distortion caused by the knives and to iron out burrs. The roller assemblies are fitted to tracks on the slitting machine and may be moved along those tracks to accommodate relocation of the knives.

Appl. No.:

09/778408

Inventors:

Kalin Liefer - Red Bud IL, US
Elroy Schoenbeck - Red Bud IL, US

Assignee:

Red Bud Industries, Inc.

International Classification:

B21D003/12

US Classification:

072/302000

Abstract:

A clamping assembly for a machine that levels sheet metal by stretching the metal beyond its elastic limit includes two jaws which have generally planar gripping surfaces. When the jaws are forced together, the gripping surfaces on them bear against the sheet metal with enough frictional contact to enable a stretching force to be applied to the sheet metal. One of the jaws includes a bearing block and a gripping pad located along the bearing block, with the gripping surface for that jaw being on the pad. A shim that is narrower than the pad lies between the pad and the bearing block. When the pad is forced against the sheet metal, the shim behind that pad causes the pad to assume a slight contour that imparts convexity to its gripping surface. This concentrates the gripping force at the centers of the gripping surfaces on the two jaws, so that perceptible indentations do not develop in the strip at the side edges of the gripping surfaces.

Appl. No.:

11/385568

Inventors:

Kalin Liefer - Red Bud IL, US
Dean Linders - Baldwin IL, US

International Classification:

B21D 1/05

US Classification:

072160000

Abstract:

A metal processing apparatus, comprising a pay-off reel for supporting and uncoiling a coil of metal, a roller-leveler apparatus adapted to receive a strip of sheet metal from the pay-off reel for conditioning the strip of steel, a recoiler for re-coiling the coil of metal, and whereby the apparatus generates enough tension on the strip of metal to improve flatness and remove coil breaks from the strip of metal as it advances through the roller-leveler.
