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.

Apparatus for feeding flat items

An apparatus for measuring the flexural rigidity in the longitudinal direction of flat items of mail transported one after another on a conveying path includes a control device, a sensor for detecting the edges of the items of mail and signaling the control device when a mail item reaches a selected bearing point, a deflection apparatus that moves into the conveying path under the control of the control device to bend individual mail items and means for determining one or both of the magnitude of the deflection of the items of mail and the magnitude of the deflection force, the control device progressing signals from one or both of the sensor and measuring means to determine the flexural rigidity of the mail item.
