Paper Pressure Foil

      This article describes a paper pressure foil for
printers, in particular pica printers.

      Pressure foils presently used in printers have, for example,
the disadvantage that the position in which they are fixed is often
changed unintentionally or that they become fully detached when paper
jams are eliminated.  This adversely affects the paper transport.

      The pressure foil described in this article does not have this
disadvantage.  It is easy to produce and may be installed in existing
printers without design changes.  In the area where it is fixed, the
foil is folded once, so that the folded portion and the original flat
foil portion are arranged at an angle of 10 to 20o (a) relative to
each other.  Both foil portions are provided with the same hole
image.  When installed, the upper notches of the foil fixing means
engage the holes of the folded foil portion, with the folded foil
portion exerting a bias on the notches.  As a result, the foil is
rigidly and self- locklingly installed.  Any unintentional positional
change is avoided.  The foil is preferably made of Mylar* and is
illustrated in the drawing.
