Abstract

A device for intermediate stacking of letters (SE) with a stacking roller (SR), stacking carriage (SW), underlying belt (UB) and a separation device. The stacking roller (SR) is mounted on the stacking carriage (SW) and a pressure gauge is provided in the vicinity of the stacking roller to measure the pressure of the stack against the pressure gauge. A device is provided for detecting possible slants in the letter stack (ST); that where such a slant is detected, the stacking carriage (SW) and/or underlying belt (UB) are made to move until the slant is eliminated; that the stacking carriage (SW) should be displaced along the underlying belt (UB) until the letter stack (ST) exerts a certain pressure on the pressure gauge provided that the detecting device does not report the presence of a slant.
