Disposable Lamination Platen Caps

      Disclosed is tooling to eliminate surface abrasion on platens
of lamination presses.  Replaceable platen caps are removed and
discarded, when worn, leaving the platen surface undamaged.

      Printed circuit panel lamination presses consist of multiple
opening hydraulic presses which apply high temperature and pressure
to the product.  The product is first "laid up" onto steel "transport
plates" which are conveyed to the press and pushed into the platens.
The platens are thick steel plates which are precision bored to
enable controlled heat-up by superheated water or steam.  The
flatness and parallelism of the platens is critical to ensure uniform
temperature and pressure are applied to the product.

      Platen caps, for example, .050-inch thick stainless steel
sheets, are attached to the wear surface area of the press platens.
The protective cap is attached at the edge of the platen and is quick
and easy to replace.  As such, the platen cap gets the wear rather
than the protected platen surface.  The caps are discarded and
replaced when worn.
