Sheet material sealing arrangement

摘要

A sealing arrangement for sealing overlapped edge portions of laminates folded onto a support member. The arrangement includes a pressure pad assembly and a drive member. An elastomeric disk is retained compressed between the drive member and the pressure pad assembly. A drive unit serves to extend the drive member to thereby urge the pressure pad via the elastomeric disk into pressure sealing engagement with the overlapped laminates on the support member.
