Abstract

The invention relates to a device for the delivery of flat objects to a friction/suction picking device with a suction head, the objects standing in a stack on a thin edge thereof on a support surface arranged on a stop surface and transported in the direction of the picking point using conveyor means. A sensor for measuring the vacuum in the suction head, is arranged on or in the suction head, which is connected to the drive controller on the conveyor means. Depending on the measured vacuum the conveyor means can be controlled such that the front object has an inclination as low as possible with the lowest possible stack pressure on the at least one friction picking device.
