US Patent:

20060070504, Apr 6, 2006

Filed:

Jul 7, 2005

Appl. No.:

11/176160

Inventors:

Daniel Downing - Hartville OH, US
David Dejacimo - Louisville OH, US
Dennis Lundell - Akron OH, US
Steven Kitz - Tallmadge OH, US
Mark Thompson - North Canton OH, US

International Classification:

B26D 1/04

US Classification:

083451000, 083614000

Abstract:

A method and apparatus is provided for cutting an elastomeric laminate that may include a layer of reinforcement cords, into a desired length without cutting through the cords. The method includes the step of cutting through the gum portion of the elastomeric composite material at a desired skive angle, and then opening up the skived cut. Next, the cord reinforcement layer is cut without severing the reinforcement cords. An elastomeric composite strip cut to the desired length is produced and has cut ends. One of the cut ends has the gum portion cut at a desired skive angle adjacent an overhang portion of the reinforcement layer. The opposite end of the elastomeric composite segment also has a skived portion to mate with the skived portion of the first cut end, and a gap in the cord ply to mate with the cord overhang of the first end, resulting in a splice. An improved anvil having independently controlled vacuum zones is also provided, as well as improved cutting mechanisms.

Appl. No.:

11/248670

Inventors:

Steven Phippen - Napanee, CA
David Dejacimo - Louisville OH, US
Paul Rust - Lawton OK, US

International Classification:

B29D 30/08

US Classification:

156130300, 156421000

Abstract:

The invention provides a stitcher and a method of stitching a helical splice having an angle φ on material mounted on a drum, the method comprising the steps of: rotating the drum at a constant speed U, traversing a stitcher assembly at a constant velocity V, wherein the stitcher assembly velocity is coordinated with the drum speed so that the stitcher engages the ply along the helical splice. The invention further provides a stitcher having a roller rotatably mounted to a support frame having a longitudinal axis, wherein the roller is pivotally mounted to the support frame so that the roller can pivot about the longitudinal axis of the handle.
