Pressure Sensitive Adhesive Label Placement Apparatus

      Sensitive electronic equipment, such as a PCMCIA card
substrate, requires that labels be precisely located on the
equipment.  A precise label placement apparatus is described.

      Label applicator equipment (Fig. 1) strips a pressure sensitive
adhesive label 1 from its paper backing (web) 2 by feeding the label
located on the web through an enclosed track.  The web is then turned
sharply around a stripping pin 3 at the end of the track which
separates the label 1 and the backing 2.  A pick-up head 4 is brought
into position abutting the label 1, while label 1 is being separated
from the backing 2, and a vacuum is applied through holes 5 in the
pick-up head 4 which retains the label 1 on the head 4.

      Once the label 1 has been picked up from the paper backing web
2, by the vacuum, the pick-up head shuttles to the left to clear the
stripping pin station and then moves vertically into alignment with a
fixed substrate locating fixture 6 via two locating pins 7 (Figs. 2
to 5).  Initially the substrate 8 is not located in the fixture 6.
The vacuum retaining the label 1 in the head 4 is turned off,
allowing the label 1 to sit freely on the pick-up head 4 via gravity.
The adhesive side of label 1 is facing up and the mylar or polyester
surface of label 1 is facing down onto the pick-up head 4.  The label
1 is now free to be moved about for alignment and accurate
registration between the label 1 and the substrate 8.
