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.

Abstract: A module for postal transmission, particularly for confidential information such as bank statements and the like, according to the invention has at least four sections (13, 15, 17, 19; 313, 315, etc.) defined by parallel fold lines (7, 9, 11; 331, 332, etc.) for repeated folding; on one of the external sections (13; 313) of the module, in the fully-folded configuration, a window (F, F1) is provided for the address; the useful face of these sections is surrounded by a perimetrical strip for permanent sealing (23A, 23B, 23C; 623) to assure the inviolability of said face, while on the reverse side of it a non-permanent glueing (25B, 25C; 125B, 125C, etc.) is provided. With respect to the known cross-folding modules, the module of the invention has a larger useful surface available, assures a higher production rate and is more easily handled.

Abstract: A form suitable for electricity, gas, water or telephone bills, bank statements etc., which can be folded and stuck down for postal dispatch, comprises at least two rectangular elongate regions which can be folded one on to the other, and sticking strips for stabilizing the folded state. The rear face of the form, i.e. that opposite the compiled or printed face, is free from partially pre-glued regions in that part of the form on which its front face is to be printed, and which can thus slide on a backing plate. In these regions sticking is carried out by distributing liquid glue when required, or by previously applying a dry thermosetting glue, and then distributing a moistening agent when these regions are to be stuck.

Abstract: In a seat for a pile of booklet components of considerable thickness a conveyor is provided which is able to withdraw the lower component of the pile and bring it into a holding position. The conveyor is driven in synchronism with the transfer of the element from the hold position to a main conveyor which, successively, receives the booklet components. This main conveyor may be driven with reciprocating movements of commutable amplitudes.
