A device for withdrawing flat items of mail from a decollating section includes conveyor belts, and guide rollers. The conveyor belts extend around guide rollers and act unilaterally upon upright items of mail. The guide rollers are individually mounted, and, at an exit of the decollating section, are rotatably disposed jointly with transfer rollers of an adjoining transfer region, which are driven independently of the conveyor belts on a common guide axle. On a side of the conveying path pressure rollers are provided at a level of the transfer rollers, which press the items against the transfer rollers. The pressure rollers are mounted pivotably at a locally fixed fulcrum, which is situated in withdrawal direction upstream thereof and laterally offset from a conveying channel, and in which rollers driven synchronously with the transfer rollers are rotatably mounted. Belts forming an inlet extend over the pressure rollers and the driven rollers.
