Abstract

The front and rear covers on a copier machine are one common part. This is possible by a unique design in both the structural foam molded part as well as the acoustic foam placed on the interior of the cover. By this method, higher production volumes are realized resulting in lower costs.

Process for Acoustic Foam in Machine Covers

      The front and rear covers on a copier machine are one common
part.  This is possible by a unique design in both the structural
foam molded part as well as the acoustic foam placed on the interior
of the cover.  By this method, higher production volumes are realized
resulting in lower costs.

      The figure shows the front of the machine with cover 10 closed
position left and right of the the breakline.  Note that the position
of the cover on the right is 180 degrees from the cover on the left.
Acoustic foam is attached to the inside of cover 10 with die cut
patterns 12 stamped into the acoustic foam.  The die cut patterns may
be removed independently of the overall piece in order to prevent
interference of the covers with the machine hardware. Patterns that
are not removed are retained by several small areas of foam that are
not cut completely through in the stamping process.  Note that the
acoustic foam cutout areas are identical in both left and right front
covers.  These same covers are also used for the rear of the machine,
thus enabling use of one cover and foam cutout design in four
positions.
