ABSTRACT:
A transfer press having workpiece gripping finger units and workpiece rests both respectively mounted in workpiece carrying -in and -out portions and idle stations defined between adjacent moving bolsters. Each of the finger units is mounted turnably up and down on central transfer bars movable into and out from the press body together with the moving bolsters without interfering with uprights of the press. Each of the workpiece rests is mounted turnably crosswise and lengthwise on the respective end faces of the individual moving bolsters on the side of conveyance of workpiece. Thus, when the moving bolsters are moved into and out from the press body, both the finger units and the workpiece rests can be automatically turned to their respective positions where they do not interfere with the uprights so that replacement of fingers and rest arms can be made readily and safely in a short time.
