A gantry press adjustment apparatus for vertically adjusting a parallel gantry press (10) with respect to a work surface (77). The gantry press has a rigid frame with a first side frame portion (12) and a second side frame portion (14), and a press roller (16) mounted therebetween. Each side frame portion has first and second generally parallel vertical members (28, 30). The adjustment apparatus has first and second planar members (40) which are adapted to receive and support the axle (60) of the press roller. The planar members are slidably mounted along a vertical axis of the frame portions. First vertical adjustment members (100, 200) are connected to the first side frame portion and to the first planar member, and second vertical adjustment members (300, 400) are connected to the second side frame portion and to the second planar member. A drive (134) is connected with each of the adjustment members to adjust each member at a substantially equivalent rate.
