Side Loading Hitch Feeder for Tape Handling

       Disclosed is a device for improving the loading and
unloading of tape or similar web material into an incremental
transfer device also known as a hitch feeding device, such as ones
used in feeding material into punch presses or electronic lead frames
into bonding machines.

      In the above mentioned invention tape or similar web material
is loaded into a hitch feeding device for feeding it into a process
machine, such as a bonding device.  One end of the tape is fed into
the feeder and the tape progress through the feeder until the end of
the reel is reached.  A problem arises when the material must be
removed in the middle of the reel.  The material must either be fed
through the device until the end of the reel is reached or the
material must be cut.  In the first case, this a time-consuming
process, and in the second case, it may not be desirable to cut the
material.

      Described here is a set of jaws that is used in the manner
usual for hitch feeders, i.e., a movable or set of movable jaws and a
stationary or set of stationary jaws to grip and feed the material.
In addition, however, this set of jaws contains a movable stop to
control the amount of opening that the jaws produce when activated
and deactivated in the process of gripping the tape.

      Figure 1 shows a top view of a gripper jaw with the movable
stop in three positions, one in the closed or operating position, one
in the open o...
