An assembly (1) for packaging products (A) comprising at least one line (2) for supplying the products (A) to be packaged, at least one dispenser (B) of covering sheets, a plurality of handling devices (3) for juxtaposing a sheet (B) on a respective product (A), and at least one output line (4) for the packaged products (A). The handling devices (3) comprise:
- at least one movable gripper for picking up at least one individual product (A) from the at least one supply line (2) and for aligning it with at least one respective packaging sheet (B);
- at least one pusher (5) for the translation of the at least one product (A) along a trajectory that is incident to said at least one respective sheet (B) aligned therewith and with contrasts for folding the at least one sheet (B) on the at least one product (A);
- at least one pair of clamping jaws (6) for the forced juxtaposition of the mutually opposite flaps (C) of the at least one sheet (B), the surface of the jaws (6) that abut against the at least one sheet (B) having a complementarily shaped embossing for the penetration of the raised portions of one jaw (6) in the complementarily shaped recesses of the other jaw, and vice versa, with the interposition of the flaps (C);
- at least one abutment for folding the portions of the juxtaposed flaps (C) that are arranged at the sides of the product (A), with consequent alignment of the flaps (C) with one face of the at least one product (A) so as to constitute a bundle (7) of gathered flaps (C);
- at least one contoured clamping plate (8) for the transverse compaction of the bundle (7) of gathered flaps (C), the at least one plate (8) being provided with at least one heater for the controlled increase of its temperature. |
