4.2.10.1 Installing Plastic Openers On Plastic Tip--Die
The purpose of the “Inside” plastic openers is to ensure that the end of the folded strip of plastic (Mylar) is
positively opened after each cut. The “outside” plastic opener performs two functions. First, helps to ensure
plastic tabs open after they are cut--off. Secondly, helps to control the piece of plastic as it opens so that it
does not “jump” out of position.
Inside and outside openers are furnished as flat pieces. In order for them to function correctly, they must be
carefully shaped and mounted into the plastic tip--die mechanism.

Step: 1. Keep upper opener straight.
Step: 2. Carefully bend “lower” portion of inside opener, along row of holes near tip, until it is just--off contact
of the die.
IMPORTANT: The openers are viewed from the back of the tip--die in this illustration (Fig. 4-36. ). Notice that
the plastic tip--die finger is shown from the narrow tip end of the finger -- not from the hinge or pivot end of
the finger.
