Patent ID: 8047761

Claim:
A device for separating moist silicon wafers from a wafer stack, the moist wafers being individually removable from the wafer stack, comprising: separating rollers on which the wafer stack is placed; a strip-off bar, which defines a gap with said separating rollers, said gap having a thickness slightly more than the thickness of a moist silicon wafer; a plunger which engages the wafer stack; and a pair of extraction rollers, wherein: said plunger presses against the wafer stack; the wafer stack is placed on said separating rollers and is subject to the pressing of said plunger, such that the lowermost moist silicon wafer can be pushed underneath said strip-off bar through said gap by the rotation of said separating rollers and can be pulled out of the wafer stack by the elastic pressure from said pair of extraction rollers aligned vertically with respect to each other and driven at the same number of revolutions as said separating rollers; and said extraction rollers are provided with rectangular grooves between rectangular strips, a conveying device constituted by one or several conveying elements; and said conveying elements adjoin said separating rollers and have a higher conveying speed than said separating rollers.
