Abstract

A singling apparatus for letters, vouchers, receipts, checks, punched cards, or other main items of all kinds up to a given size and thickness, singles out the items arriving in any irregular sequence one below the other, unarranged and oriented on a longitudinal or transverse edge. To obtain a high singling output and draw-off quality, the items are transported in vertical position through a transport mechanism and, by using a restricting guiding unit, into the draw-off region of a draw-off belt revolving about deflection bodies tangentially toward the draw-off belt surface. In the contact zone of draw-off belt and one deflection body the inflowing mail items are pressed against the draw-off belt and only the items coming into contact with the draw-off belt directly are drawn off by friction, by deflection of these items around the deflection body.
