ABSTRACT:
A hold-down beam is provided on a rapid acceleration conveyor to hold articles, such as an unstable stack of newspapers, tightly against the conveyor for providing frictional engagement between the stack and the conveyor and move the upper part of the stack with the conveyor so that the stack will not topple. The hold-down bar is unpowered, that is, it is mounted for reciprocation in low-friction bearings so that its own frictional engagement with the top of the stack carries it along with the top of the stack until the stack is brought up to the desired velocity. A unique cable system for lowering both ends of a hold-down bar synchronously through an infinite number of positions and does not interfere with operation of a strapping machine.
