An improved imbricating method, folding method, and device for producing imbricated streams (3) which are produced from singulated and preferably folded blanks (2) is provided. The method includes taking imbricated bundles of blanks including of a number of overlapping blanks corresponding to the number of the individual streams formed by the blanks of a first individual stream being transported at a distance from one another along a transport surface through a compiling station. In the process, the blanks of the at least one remaining individual stream are first of all deflected vertically with respect to the transport surface by a deflecting device of the compiling station and are then guided in the direction of the first individual stream and are subsequently deposited with an offset onto the blanks of the first individual stream.

An assembly for realizing in continuous covering jackets of book elements of different dimensions starting from a film wrapped up in a coil. The assembly includes a mechanism for cutting the film unrolling from the coil for realizing pieces of the film; a first folding device of a first end of the pieces; a second folding device of a second end of the pieces; a control and command unit and a longitudinal welder suitable for both superiorly and inferiorly closing folded pockets and for regulating the height of the cover itself by trimming the parts in excess.

A folding machine for paper handkerchiefs is disclosed. The folding machine includes a longitudinal folding unit and a transverse folding unit, wherein the longitudinal folding unit executes a longitudinal folding procedure to a paper web to obtain a paper web with longitudinal folds, and the transverse folding unit receives the paper web with longitudinal folds from the longitudinal folding unit and cuts it into paper handkerchiefs before executing a transverse folding procedure to the paper handkerchiefs, thereby completing the folding process for paper handkerchiefs. After being folded longitudinally and transversely, the paper handkerchief is effectively reduced in size for packaging and is convenient for users to carry.

A machine to produce stacks of folded pop-up wipes from material that is threaded along a path having a direction through the machine. The machine includes a holder, a first tension unit, a perforation unit to generate perforations in the material in a direction orthogonal to the direction of the path, and a folding unit to fold the material in a direction orthogonal to the direction of the path. The material is threaded along a path through the machine via the first tension unit, the perforation unit and the folding unit. A control unit controls the machine to produce folded pop-up wipes by individually controlling tension of material along one or more sections of the path and to increase tension of the material in a section of the path located after the perforation unit to stretch a generated perforation in the section of the path by a target distance.

An interleaving unit, comprising a pair of rolls (1, 2) set alongside one another and counter-rotating and provided with respective first and second folding tools (3, 4; 5, 6) set at a distance from one another along the circumferential development of the respective peripheral surfaces so as to operate in a common point of tangency (Z) on a succession of sheets (7a, 7b) fed between the two rolls, said tools (3, 4; 5, 6) being set on respective mobile cylinder sectors (8, 9, 10, 11) to enable positioning thereof at an adjustable distance apart along the circumferential development of a corresponding roll (1, 2), said interleaving unit comprising means (M1, M2, U) for independently adjusting the speed of rotation of one or more of said sectors according to their angular position in order to reduce or increase the peripheral speed of said sectors with respect to a speed of feed (Vm) of said sheets.
