Abstract
A table feeder apparatus comprises a base, a feed screw rotatably supported on the base and a motor for rotating the feed screw about a feed axis. A feed nut is mounted on the feed screw and a block is mounted integrally with the feed nut. A table is disposed on the block for movement along the feed axis. In one aspect, a slide mechanism is disposed between the block and the table. The slide mechanism is slidable in at least one of a horizontal direction and a vertical direction transverse to the feed axis. During movement of the table, the slide mechanism slides to absorb a force applied to the feed nut, tending to displace the block and table in a direction transverse to the feed axis, to prevent the applied force from being transmitted to the table. In another aspect, the table is provided with an opening in which a table portion is removably fitted. Removal of the table portion facilitates maintenance of the slide mechanism without requiring the entire table feeder structure to be dismantled.
