Abstract
A feed table apparatus (30) for moving a workpiece (31) toward a machine tool. The apparatus (30) comprises a roller assembly (32) which provides rolling support of the workpiece (31) toward machine tool and a shuttle vise assembly (36) for moving the workpiece (31) longitudinally along the roller assembly (32). The shuttle vise (36) includes a reaction frame (37) having a first upright post (40) and a second upright post (40'"'"') A coupling mechanism (43) movably mounts the reaction frame (37) directly to the elongated roller framework (33) for longitudinal relative movement therealong. The coupling mechanism (43) further couples the reaction frame (37) to the roller framework (33) in a manner transferring reaction forces, caused by clamping the workpiece (31) with opposing vise jaws (41, 41'"'"') to the roller framework (33).
