Abstract: A method and device for forming groups of flat products, in particular biscuits, for supply to a wrapping line, whereby the products, on a supporting surface, are withdrawn by a conveyor unit and transferred onto a pocket conveyor in a sequence having a series of gaps between adjacent products. Each pocket on the conveyor being designed to receive a respective group of products, and being defined by two projections, each of which travels in time with a respective gap through a loading station where the products are loaded onto the pocket conveyor.

Abstract: A unit for compacting groups of flat products arranged side by side and on edge, whereby a through conveyor feeds the groups, with the products separated axially, into successive engagement with a compacting device having a number of pairs of compacting elements on either side of the conveyor; the compacting elements in each pair traveling with the conveyor, being positioned facing the opposite ends of a respective group, and being brought together for transversely moving the products in the group into contact with one another.

Abstract: Tubular obtained from a sheet which has, on its inner surface, in contact with a product to be wrapped, two longitudinal bands which are coated by a layer of cold-adhesive; the two longitudinal bands are glued to one another with the interposition of an end portion of a tear-strip, the opposite surfaces whereof are coated by respective layers of cold-adhesive.

Abstract: A supply device for supplying flattened boxes (1) to a packaging machine, equipped for the re-supply of the boxes (1), comprising apparatus for feeding a line (4) of boxes along a magazine (2) including a front carriage (13) and a rear carriage (14) feed chains (6, 8), flat vertical slides (19, 27) for connecting the carriages (13, 14) to the feed chains (8), a double action pneumatic jack (42) for sliding the carriages (13, 14) towards or away from one another, a plate (31) mounted on the carriage (13) moveable transversely between a position facing the line (4) and a retracted position, a plate (41) on the carriage (14) facing and normally spaced from the plate (31) to form a space containing additional boxes (1). To supply the additional line (46) of boxes, the plate (41) is first moved to compact the additional line (46) and thereafter plate (31) is retracted to provide a single line of boxes.
