Appeal 2007-0512
Application 10/310,744
4. Appellants describe the seaming assembly with respect to Figure 7,
shown here:
Pressure roller 10 [not labeled: 10 comprises 12, 14–16, and 18]
having distal end 16 and proximal end 18 travels on both sides
of fastening means 26 exerting sufficient pressure onto the
overlapped portion of the overlapping thermoplastic sheets [22
and 24] to produce a weld therebetween. * * * Portions of the
rubber cushion [15] directly over the fastening means are
compressed, while portions of the rubber cushion adjacent to
the fastening means conform to the underlying second
thermoplastic sheet and in sufficiently tight contact therewith to
expel air from between the overlapping portions of the
thermoplastic sheets so as to allow formation of air pockets or
bubbles.
(Specification at 9, bracketed labels added for clarity.)
