ABSTRACT:
The objects of the invention are generally accomplished by a method of delaminating imaging materials comprising providing an imaging material comprising donor and receiver elements, heating said imaging material, applying opposed forces to said donor and receiver elements to separate said imaging material into donor and receiver elements, and accumulating the separated donor element. In a preferred method one or both of said opposed forces is vacuum and when the vacuum is released from said donor element, accumulating takes place by spooling after separation.
The apparatus for delamination of imaging materials comprises means for applying heat and pressure to said imaging material, means to apply a separating force to at least one of said donor element and receiver element forming said imaging material and means to separate said donor element and said receiver element. In a preferred embodiment the apparatus further comprises means to spool said donor element and means to preheat said imaging material prior to applying said separating force.
