Abstract:
A method for demounting workpieces attached to an adhesive surface of an adhesive film, the adhesive film having a bottom surface, the method comprising the steps of:(a) providing a workpiece demounting apparatus comprising a plurality of substantially parallel blades, wherein: each of the blades has a substantially linear blade edge; each blade edge lies within a blade-edge plane that is substantially perpendicular to the blades; and the spacing between the blades is small enough to support said workpieces, whereby the plurality of blade edges provides a substantially planar blade-edge surface (b) moving the bottom surface of the adhesive film into contact with the blade-edge surface; (c) forcing the adhesive film through the blade-edge surface so that the blade edges cut the adhesive film and support the workpieces while the adhesive film is pulled free from the workpieces.
