ABSTRACT:
Rotative inserting unit for documents and sheets of paper for use, in particular, with automatic equipment for the printing and the inserting of said materials into envelopes. The unit comprises a drum (14) for the feeding of the already folded sheets, rotating intermittently, on the side surface (14a) of which transport seats are formed for the paper sheets, on subsequent angular portions of the surface, as well as fixed guide means (19) inside which said surface rotates. A conveyor (21) for the envelopes is also provided for, located at the exit of an automatic distributor box (24) of the envelopes and converging towards the exit of said guide means (19) in a position substantially tangent to the surface of said drum and in correspondence with the opening of a mobile pocket (33) for the temporary collection of the envelopes. There are further provided means (41) for lifting at least one edge delimitating the mouth of the envelope periodically contained inside said pocket in order to allow the insertion of the sheet exiting said guide means.
