Apparatus For Forming An Adhesively Bonded Seam Between Resiliently Compressible Fabric Sheets
US Patent:
5693177, Dec 2, 1997
Filed:
Aug 3, 1994
Appl. No.:
8/285240
Inventors:
Mark J. Meltzer - San Francisco CA
Tommas J. Tompkins - Berkeley CA
Tommas J. Tompkins - Berkeley CA
Assignee:
O'Neill, Inc. - Santa Cruz CA
International Classification:
B29C 6508
US Classification:
156502
Abstract:
An apparatus for forming a butt seam between opposed edges of resiliently compressible fabric sheets, such as foamed neoprene for wet suits and dry suits. The apparatus includes fabric manipulating assembly which continuously compresses the sheets proximate and inwardly of the edges, preferably by a roller assembly, to form opposed shoulders or areas that will permit the application of a lateral force to firmly press the opposed edges of the flexible and compressible sheets tightly together during movement and bonding along the seam. The apparatus preferably includes adhesive activation means in the form of an ultrasonic transducer which contacts the neoprene pieces in advance of compression rollers to activate a dry neoprene cement carried on the edges of the fabric pieces. A method for forming the butt seam is described, as are alternatively adhesive activating assemblies and a seamed neoprene fabric sheet.
