ABSTRACT:
The rear cross rod that supports the carrier rods insertable in grooves in a stacking table for continuing the lifting of a residual stack while the table is lowered for loading a fresh stack without interrupting operations from the top of the residual stack, supports the cross rods from hanging collar brackets on its underside so that the rear cross rod has its body above the carrier rod and is adjustable along the length of the carrier rod and can function as an effective rear stack stop to stabilize the stack position. In one embodiment the rear cross rod is fixed in its position for a particular stack size by clamping sliding brackets on lateral rods that run from the respective ends of the front cross rods back to an extremity at which the rear chains of the hoist are connected. In another embodiment the rear cross rod is suspended directly by the rear hoist chains that run over pulleys which are adjusted horizontally to position the rear cross rod, while a scissors mount held on the rear support pillars of the frame of the sheet-feeding mechanism is provided that may be clamped in position to prevent rearward swinging of the rear cross rod once it has been moved into position. The pulley system in this case makes possible horizontal adjustment of the rear cross rod without change of the level at which it is suspended.
