ABSTRACT:
An indexing mechanism for a three-dimensional transfer press system wherein a pair of parallel spaced transfer bars are moved back and forth, up and down, and toward and away from each other for transporting successive panels through a series of press stations. A height adjustment for the transfer bars are connected between a lift cam mechanism and a rack-and-pinion linkage, the latter linking the former to two pairs of lift carriers carrying the transfer bars so as to allow their longitudinal reciprocation and movement toward and away from each other. Comprising either a multiple abutment member, a screw-and-nut assembly, or a double-acting hydraulic cylinder, the height adjustment provdes a variable length of connection between the lift cam mechanism and the rack-and-pinion linkage for adjustably varying the upper and lower limits between which the transfer bars are moved up and down.
