Abstract

An apparatus for separating and drawing off a film from a laminate, the laminate including the film and a carrier material upon which the film is laminated. The apparatus includes a first plate; a second plate being disposed above the first plate; a motor; a spindle being operatively connected to the motor; a separating apparatus being movable along the spindle above the first plate and including a wedge-shaped separating knife; a gap which lies above and parallel to the separating knife and which is inclined at an oblique angle relative to a horizontal plane; and a stay passing vertically through the first plate which holds an underside of the laminate firmly in place. The laminate rests on the first plate, and the separating apparatus moves into engagement with a corner of the film such that the film corner is detached from the carrier material and is threaded into the gap. The stay holds the underside of the laminate firmly in place when the film corner is threaded into the gap.
