Abstract: A process for producing a hard roll for use as an elastic roll for making paper calendering by casting a liquid thermosetting resin material into a space between a metal roll core and an outer mold, and thereafter heating the resin material from outside to cure a major portion of the material and to form an outer layer resin intermediate body, while cooling the resin material from the roll core side to leave a viscount liquid resin material layer inside the intermediate body. The intermediate body is subsequently cooled from outside the outer mold to contract the body, allowing an excess of the liquid material to be forced out upwardly with the contraction of the body. The material is thereafter heated from the roll core side to cure the remaining viscous liquid resin material. The hard roll can be produced without cracking due to the reaction contraction and thermal shrinkage of the thermosetting resin. The roll is usable without cracking in its surface hardness despite the influence of heat.

Abstract: Method for assembling staple drivers in a cartridge to be used during surgery includes a fixture having tapered converging passageways to guide staple drivers into alignment with pockets in the cartridge. After the staple drivers are properly in place to be pushed into the pockets of the cartridge, a plunger with blade-shaped projections descends such that the blades project through the fixture and the passageways therein to push the drivers into the pockets. To prevent the drivers from falling out of the pockets through the entrance opening where they were inserted, a pocket locking or blocking element is applied to the cartridge after the drivers are in the pockets.
