Abstract

A journal bearing block (10) has opposed sides (62, 63) received in sliding relation between the opposed sides defined by gibs (14, 16) of a slot (18) of a printing press sideframe (12). One of the gibs (14) has an elongate groove (54) and one of the bearing block sides (62) has an adjacent elongate groove (74). A key (86) is received by the bearing block groove (64) and includes an outstanding portion (90) extending into the gib groove. The key includes a threaded opening (70) and is connected to the bearing block by a rotatable adjustment screw (74). The key is narrower than the bearing block groove but substantially the same thickness as the gib groove, whereby rotation of the adjustment screw causes the key to travel laterally in the bearing block groove with the result that the bearing block, with its rotary die journal travels laterally relative to the sideframe (12). One of the gibs defining the sideframe slot is adjustably attached within its associated groove ( 30) by rotatable adjustment fasteners (40) having an eccentric portion (42) to move said gib and the other gib is fixedly attached with its associated groove (32) to vary the width of the sideframe slot.
