Abstract: A rocker cover assembly for a cylinder head of an internal combustion engine includes a rock cover, a gasket element and a stabilizing core. The gasket element is disposed between the rocker cover and the cylinder head, and includes a sealing material. The stabilizing core is inserted in the gasket element and surrounded at least essentially completely by the sealing material of the gasket element. The stabilizing core is isolated from the rocker cover such that the sealing material of the gasket element is arranged between the stabilizing core and the rocker cover.

Abstract: A cap-lining machine is disclosed for producing cap liner inserts of the type used to provide a tamper evident seal on the tops of bottles and other containers. To facilitate removal of this seal, it is desirable to have a tab attached to one edge of the seal which can be grasped to pull the seal off the top of the bottle. The liner insert, with an attached tab, is formed in one step by a mating punch and die, each having first and second portions corresponding to the primary portion of the cap insert and the tab, respectively. The structure of the punch and die is such that the tab first is formed and then is folded beneath the main portion of the cap insert in a single operation. The punch includes a reciprocating tamper inside the main portion for pushing the cap insert, with the folded under tab, into a cap located beneath the punch.

Abstract: A cap lining machine constructed with a minimal number of mechanical parts includes a spring-biased shuttle feed for moving the caps into the punching and insert position. A cam pulls the shuttle back against the bias of the spring; so that upon release by the cam, the shuttle pushes the caps to the insert position. If a cap becomes jammed, the spring-biased shuttle simply is held back against the spring bias to prevent breaking of caps or parts of the machine. A tamper also is concentrically mounted within a hollow punch and is controlled by a rocker arm assembly to press punched inserts out of the lower end of the punch and seat them into the caps. The tamper may be cleaned by removing it completely from the top of the punch.
