ABSTRACT:
An automatic taping machine for automatically applying tapes to lead frames includes a lead frame feeding mechanism and a tape feeding mechanism with an automatic cutter and applying mechanism for automatically cutting and applying strips of tape to the lead frame. The cutting mechanism is adapted to eliminate the waste in tape and utilizes the entire roll of tape fed to it and includes feeders for feeding tape from both sides to a double cutter head which cuts strips of tape across the entire width of the tapes and includes a vacuum holder for holding the tape to a face of the cutter head for then applying the tape to the lead frames. The frames are advanced through the mechanism and the tapes applied and then fed through a heating press for heating the tape and securing it in place on the lead frames.
