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 punch press has first and second sets of tooling mounted longitudinally of a press conveyor belt. The second set of tooling is located externally of the usual press columns. A second ram slidably mounted on the outside of the columns is driven by a connecting arm eccentrically mounted on a crankshaft extension. The second ram drives the upper tooling of the second tooling set in a reciprocating manner. The second ram can be operated out of phase with the main ram to reduce the total tonnage required of the press.

Abstract: A press for converting work pieces into finished parts has an elongated bolster mounted on a press bed. The bolster supports columns on which a ram is slidable. The bolster also supports the lower die shoe of the press tooling. A conveyor or transfer system mounted on the bolster carries work pieces into and out of the area of the tooling. The bolster is a unitary piece which integrates support of the die shoe, columns and conveyor to assure proper cooperation and alignment among them. A pivotable carrier mounts a feed mechanism for feeding a stock strip into the tooling. Power to the feed mechanism is supplied through a shaft which is coaxial with the hinge line of the carrier, so that the carrier can be swung away from the tooling for service access without requiring disconnection of the power supply. A traveling vacuum box on the lower die shoe supports the conveyor for vertical as well as longitudinal motion, and retains the work pieces on the conveyor.

Abstract: A tamper evident safety seal is formed from a sealing liner having an integral tab portion, the tab being double folded for increased strength.

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.

Abstract: A cap-lining machine is constructed with a minimal number of mechanical parts and is provided with a modular and quickly replaceable liner punch and insert station, which readily may be changed to accommodate caps of different diameters with a minimum amount of down time. In addition, sensing switches are employed with an electronic control system in lieu of conventional mechanical connections to prevent the machine from moving on to the next step in its operation unless all previous steps of operation have been completed in proper sequence. Operation interruption is accomplished in a jam-proof manner.

Abstract: A method and apparatus for blanking, folding and inserting induction heat sealable membranes, having a disc and integral tab portion, in container covercaps in one continuous punch stroke. The tab portion is blanked from foil stock and folding of the tab is initiated during tab blanking along a fold line located at the periphery of the disc portion. The disc portion of the membrane is then blanked while continuing to fold the tab portion to an intermediate reverse folded position. The blanked membrane is then inserted into an overcap to press the tab between the membrane disc portion and the covercap to further fold the tab along the fold line.
