The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “ “The present disclosure generally relates to the production of composite laminat e parts, and deals more particularly with a method, apparatus and system for sep arating a poly backing film from composite prepreg. “Thermoset preimpregnated (“prepreg”) composite material is normally supplied as a single ply thickness in roll form having an adhered poly film layer on one si de of the ply. The poly film layer functions to prevent layer-to-layer sticking when the material is in roll form or stacked as sheets. The poly film layer, som etimes referred to as “backing paper” remains on the ply to prevent sticking whi le it is being stored and/or cut to a final shape. The poly film layer must be r emoved before the ply is laid up to form a composite part. The use of automated equipment to remove the poly film layer in high production environments can be c hallenging because the removal process must begin with the initial step of separ ating film layer from the ply along an edge of the ply. Separating the film from the ply is also challenging because the separation process must avoid damaging or contaminating the ply.
