A turnover mechanism for turning a planar strip through one hundred and eighty degrees is disclosed. The turnover mechanism is particularly useful in the manufacture of tackless strips and is adopted for installation in a tackless strip manufacturing machine. The turnover mechanism includes a ratchet which is activated by the usual pin driving mechanism to rotate a turner in timed sequence with the pin inserting operations. The turner includes a groove and the turnover mechanism incorporates a cam to urge one end of each strip into the groove after the pins are properly seated in the strip. The turner turns over or flips each pinned strip in sequence to permit the tackless strip manufacturing machine to automatically apply a plurality of floor attaching nails in each strip in a direction opposite to the orientation of the pins.
