Synthetic resin cured in place rotary embossing counter and method of preparing same

Abstract From the Canadian patent

A resurfaceable rotary die counter is prepared by employing a cylindrical counter core having a central circumferentially extending relieved area filled with readily replaceable synthetic resin material containing pretensioned, spirally wound glass fiber roving which renders the resin craze and crack resistance even under extended continuous we. Economical counter production is possible because of preparation of the counter on the press during makeready using the die as a counter forming element. The resin is run in against the die prior to hardening of the same to form a reverse design surface in the counter which exactly mates with the doe surfaces. A viscous resin having a minimum …
