Bar feeder with centering apparatus

Holder apparatus for elongate stock while feeding to a processing station having an input axis and comprising:

• an elongate stock holder for receiving the stock therein and holding the stock with the stock having an axis colinear with the input axis;
• an offset adjuster operable to move the holder transverse to the input axis to enable establishment of colinearity of the stock axis with the input axis for separate lengths of stock having different dimensions from stock axis to stock perimeter;
• the holder including a trough for supporting the stock, and a guide associated with the trough to confine the stock against the trough;
• and
• a guide mount,
• the guide being connected to the mount by at least two links and movable thereon in parallelogram manner,
• the adjuster being coupled to the trough and to the guide mount and operable, when actuated, to move the trough and the guide mount simultaneously and transversely but in opposite directions relative to the input axis.

• a stock pusher carriage mounted for movement parallel to the holder and guidedly movable along the holder;
• a pusher member on the carriage and extending in the holder to engage stock received in the holder and operable, when the carriage is driven along the holder toward a processing station, to drive the stock into the processing station, the pusher member including;
• a blade clamped in the carriage;
• and
• a rod extending longitudinally in the holder, the blade being received in a transverse groove in the rod to drive the rod longitudinally.
