The invention concerns a destacking device with a retractable blowing element. The device (1) for destacking flat objects comprises a magazine (M) for feeding flat objects, in which the flat objects are stacked on edge and moved in a certain direction (D) so as to reach a destacking plate (6) placed in the extension of said feed magazine, in order to be ejected one-by-one in a direction (P) perpendicular to said certain direction (D), the device also comprising a blowing element (13) which is provided for sending a stream of air to the flat objects and is retractably mounted in the destacking plate.

A take-out device (1) includes a take-out mechanism (3) which takes out postal matters (P) supplied to a take-out position (20) at one end of a deposit section (2) one by one, a separating mechanism (5) which separates second and subsequent postal matters that are carried along with a postal matter to be taken out from the take-out position, and an auxiliary mechanism (6) which applies a negative pressure to the postal matter on the take-out position so as to feed it in both forward and opposite directions. The separating mechanism (5) applies a negative pressure to the postal matter on the conveyance path (10) via a plurality of adsorption holes (31a) of a separating roller (31) so as to adsorb it, and applies a separating torque in an opposite direction to the take-out direction (T) thereto.

A method and apparatus for feeding envelopes in an envelope insertion machine, wherein a rotatable pneumatic feeding head (40) is used to pick up an envelope from an envelope stack by a negative air pressure. The pneumatic feeding head is also used to move the envelope to a pair of take away rollers (26) so that the envelope picked up by the feeding head can be moved further away from the envelope stack. It is preferred that the feeding head includes an outer cylinder (50) having a row of vacuum ports (42) and an inner cylinder (60) having a plurality of apertures (62) for air passage operatively connected to a vacuum pump. The inner cylinder (60) is independently rotatable relative to the outer cylinder (50) so that the negative air pressure is provided to the vacuum ports (42) when the apertures (62) of the inner cylinder (60) are aligned with the vacuum ports (42), and the negative air pressure is turned off from the vacuum ports (42) when the apertures (62) and the vacuum ports (42) are out of alignment.
