Edge Cut To Increase Effective Width Of Insulation Sheet And Method Of Forming The Same
US Patent:
6711863, Mar 30, 2004
Filed:
Feb 25, 2002
Appl. No.:
10/081066
Inventors:
Richard Napoleon Cunningham - Aurora CO
Judith A. Wunsch - Willows CA
Judith A. Wunsch - Willows CA
Assignee:
Johns Manville International, Inc. - Denver CO
International Classification:
B26D 115
US Classification:
524041, 83428, 834253
Abstract:
An insulation sheet for insulating a wall, floor, ceiling or roof cavity is flexible, compressible and resilient and has lateral edges extending the length of the sheet. The lateral edges of the sheet are formed with contours along the lengths of the lateral edges, which with the flexibility, compressibility and resilience of the insulation sheet, increase the effective width of the sheet, relative to a conventional insulation sheet of the same length, width, thickness and density with straight lateral edges extending perpendicular between the major surfaces of the conventional sheet, with no or substantially no increase in the amount of insulation material forming the sheet relative to the insulation material used in the conventional insulation sheet. The contours of the lateral edges are formed by reciprocally oscillating or angling cutting blades in a direction transverse to the feed of a sheet past the cutting blades.

Abstract:
An insulation sheet for insulating a wall, floor, ceiling or roof cavity is flexible, compressible and resilient and has lateral edges extending the length of the sheet. The lateral edges of the sheet are formed with contours along the lengths of the lateral edges, which with the flexibility, compressibility and resilience of the insulation sheet, increase the effective width of the sheet, relative to a conventional insulation sheet of the same length, width, thickness and density with straight lateral edges extending perpendicular between the major surfaces of the conventional sheet, with no or substantially no increase in the amount of insulation material forming the sheet relative to the insulation material used in the conventional insulation sheet. The contours of the lateral edges are formed by reciprocally oscillating cutting blades in a direction transverse to the feed of a sheet past the cutting blades and/or by placing the cutting blades at an angle other than perpendicular to the major surfaces of the sheet being fed past the cutting blades or by synchronously moving the cutting blades back and forth between a negative and a positive angle as the insulation sheet is fed past the cutting blades.
