Abstract: An upstacker reject device includes a reciprocating plunger connected to a selectively oscillating shaft. A bellcrank is adjustably connected to a press ram and a rotatably mounted cylinder. A clutch is engaged to transfer rotary motion from the cylinder to the shaft. As the press ram travels downwardly, the cylinder and shaft are rotated, thereby causing the plunger to travel upwardly and engage an article carried by a transfer belt. A cylinder assembly and motion restriction cooperate with the clutch to insure that the plunger is retracted before the belt is advanced.

Abstract: A resilient tool support for mounting either an upper or lower tooling member on a press ram or stationary press bed for performing a variety of operations on easy open can ends. The resilient tool support comprises a metallic member having a longitudinal central bore with vertically spaced overlying pairs of diametrically opposed angularly oriented segmental slots extending inwardly through the sides of the resilient tool support block reaching the central bore. The resilient tool support may be positioned between either the press ram and the upper tooling member, or the stationary press bed and the lower tooling member. The resilient tool support is designed to yield and absorb excessive pressure of the press ram as it performs the various operations on the easy open can ends.

Abstract: The application discloses a can body trimmer which may be a free standing unit usable along with existing can body making machines, or which may be combined with a can body making machine as an integral part thereof. The apparatus trims the excess metal from the open end of a can body without leaving burrs, at a high rate of speed, and provides a can body trimmed to a precise side wall length for subsequent finishing operations including flanging, or necking and flanging to facilitate installation of the end closing lid after the can has been filled.

Abstract: An apparatus is disclosed for simultaneously necking and flanging metal cans. A collapsible mandrel is provided, which in the collapsed condition will accept a can and which in the expanded condition grips the can over its entire inside surface. The mandrel is constructed such that in its expanded condition it presents an uninterrupted cylindrical surface. The mandrel has a groove in the region where the necking-flanging operation is to be performed and an elastic material is seated in the groove. A die ring larger in diameter than said mandrel in its expanded condition is mounted rotatably coplanar with said groove and means are provided to move said die ring radially of the mandrel to produce the necking and flanging operation by cooperation with the elastic material in said groove. Expansion and collapse of the mandrel is accomplished by internal cam structure.
