A conversion system for converting easy-open can ends has an improved slide assembly capable of handling multiple conveyor belts with improved tension and vibration control. The slide assembly includes a stationary idler shaft mounted transverse to the conveyor axis on a take-up slide. At least two guide pins extend from the shaft parallel to the conveyor axis. Each guide pin mounts a cylindrical bearing holder thereon. The bearing holders are both pivotable and slidable on the guide pins. Springs disposed in pockets in the idler shaft bias the bearing holders. The bearing holders each mount a drum for rotation with the drum.degree. s axis parallel to the idler shaft. The pivoting of the bearing holders accommodates conveyor belt camber while the sliding permits tension adjustment and control.
In a conversion system of the type having cooperatively-engageable, reciprocable upper and lower tooling defining a plurality of stations having tools which progressively convert shells into can ends, at least one endless conveyor for indexing shells into and through the stations of the tooling, the conveyor revolving around head and tail pulleys and defining a longitudinal axis, the improvement comprising a pulley for use as either a head pulley or tail pulley, comprising:
