Abstract
An arrangement for separating of individual sheets from a stack of sheets, this arrangement comprising a rotatable pulley close to the uppermost sheet, which as a system of ducts connectable to a source of vacuum, with one or more openings which open out onto the periphery of the pulley, and an endless belt driven slip-free round the pulley with through-perforated holes which are arranged so as to coincide with the said opening of openings on the pulley to form suction elements to make possible the lifting off of sheets, one-by-one, from the stack.
