Abstract
1494215 Moulding seals FEDERALMOGUL CORP 10 Dec 1974 [19 Dec 1973 (2) 13 Nov 1974] 5001/77 Divided out of 1494214 Heading B5A [Also in Divisions F2 and B6] A sawtooth formation on the face of an annular seal element 35 is produced in a multiaction die by coining a web of p.t.f.e. between a first die assembly 40 with an annular spring- supported coining member 80 having a flat gripping portion 81 and a shaped gripping portion defining recesses into which said wafer material cold flows during coining, and a second die assembly 42 having a gripping member 60 opposite said coining member 80. The die also pierces and trims the annular seal member. Reference is made to the parent Specification which claims the seal.
