ABSTRACT:
A roller table with a vise carriage and movable roller supports for moving, positioning, and supporting material. In the preferred embodiment, a hydraulic cylinder and piston rod are used in conjunction with a rack and pinion system such that there is a doubling effect on the piston rod stroke for effectuating differential positioning of two movable roller supports and the vise carriage. One movable roller support is disposed at approximately the midpoint between the vise carriage and a fixed vise. For a given displacement of the vise carriage, the movable roller support travels half as far so as to remain essentially at the midpoint of the span. The second movable roller support is disposed on the other side of the vise carriage, more or less at the midpoint between the vise carriage and a fixed roller support. The second movable roller support is integral with the first movable roller support and, thus, also travels half as far as the vise carriage for a given displacement so as to remain essentially at the midpoint between the vise carriage and the fixed roller.
