A stock feeder for repetitively feeding uniform segments of a continuous web of stock material from a roll to a production machine. The feeder comprises a frame, a pair of hold clamps located on the front portion of the frame, and a movable feed block which carries a pair of feed clamps that grips and pulls the stock material to a position which is held by the hold clamps. To obviate the necessity to reposition the clamps when changing the width of stock material, the frame includes first and second pairs of laterally adjustable stock roller guides located, respectively, on its front and rear portions. Also, to enable the feeder to operate faster without destruction or deterioration, and yet still attain good positioning accuracy of the stock material, the movable carriage includes a double acting hydraulic shock absorber rod which engages, respectively, at its forward and rearward stroke limits, an adjustable stud in the front portion of the frame and a fine adjustment stop bar disposed at the rearward portion of the frame. A pad of elastomer material also is used to cushion and reduce impact noise of the shock absorber.
