ABSTRACT:
A device for collating sheets, in which the sheets are offered at an input of the device, which comprises conveyor member which convey the sheets in a circuit arranged between the input and an output of the device, the conveyor member comprising at least a first pair of helical ramps with a predetermined winding direction and each comprising a free end. The ramps are arranged on rotating member which rotate them about their helix axis in the opposite direction to the winding direction. The device also comprises guide and placement member, the rotation of the ramps having the effect of conveying the sheet positioned, by the guide and placement member, on a predetermined portion of each of the two ramps, along a portion at least of the circuit and toward the free end of the ramps, a first of the two ramps of the pair having an opposite winding direction in relation to the second. In a first variant, the device is characterized in that each of the ramps comes into contact with the sheet approximately transversely to the movement of arrival of the sheet to guide it laterally. In a second variant, the device is characterized in that it also comprises a second pair of ramps, arranged downstream from the first pair in relation to the movement of arrival of the sheets, the first ramps and the second ramps of each of the two pairs having respectively an identical winding direction and the first ramps of each of the two pairs having a height greater than that of the second ramps of each of the two pairs.
