摘要： Described herein is an apparatus and a method for removing an epoxy resin from a backing sheet at a temperature at or below the glass transition temperature of the epoxy resin. The apparatus (200) comprises a housing (210) in which is mounted a dispensing roll (220) comprising epoxy resin (230) on a backing sheet (240), a wind-up roll (250) comprising the backing sheet (240), a release element (260) over which the backing sheet (240) is directed, and a collection tray (270) for collecting pieces of resin (230a) removed from the backing sheet (240). The dispensing and wind-up rolls (220, 250) are mounted on respective drive shafts (225, 255) which are driven by a drive mechanism (285) controlled by a controller (280). A temperature controller (290) is also provided for controlling the temperature within the housing (210) so that it remains below or at the glass transition temperature of the epoxy resin. Angle (αa) is chosen to optimise the peel-back angle of the backing sheet (240) after is passes over the release element (260) in relation to the relative spacing between the dispensing and wind-up rolls (220, 250) and the release element (260).
