The invention relates to a wrapping machine for wrapping a load with a film including at least one operating unit for performing operations on the load or on the film and a conveying device for moving the load along an advancing direction through the machine. The machine includes a movement system that is adapted for moving the operating unit and comprises a shuttle assembly movable along a path and arranged for supporting and moving the operating unit. The shuttle assembly and the conveying device are drivable in a coordinated manner in order to enable the operating unit to perform operations on the load wrapped with the fi8lm even while the load is moved along the advancing direction and out of the machine.

A machine for wrapping a load with a film made of synthetic plastics includes a first frame suitable for supporting second frame that rotatably supports around, and slidably parallel to, a wrapping axis at least one wrapping unit including a reel of the film and a roller assembly arranged for unwinding and prestretching the film. The second frame is slidably mounted on the first frame and is movable along an advancing direction that is transverse, and in particular orthogonal, to the wrapping axis. A conveyor is provided for moving the load along the advancing direction. The conveyor and the second frame are movable in a mutually coordinated manner to wrap the load with the film also while the load is moved along the advancing direction.

APPARATUS WITH HIGH LEVEL OF AUTONOMY FOR THE CYCLICAL FEEDING OF A LARGE FLOW OF TRAYS, BOXES OR OTHER DIE-CUT CORRUGATED CARDBOARD SHEETS FOR PACKAGING, TO A CONVEYOR LINE THAT FEEDS IN PHASE THESE DIE-CUT CORRUGATED CARDBOARD SHEETS TO A HIGH PRODUCTION CONTINUOUS PACKAGING MACHINE.
Apparatus with high level of autonomy for the cyclical feeding of a large flow of trays, boxes or other die-cut corrugated cardboard sheets (F) for packaging, to a conveyor line (1) that feeds in phase these die-cut corrugated cardboard sheets to a high production continuous packaging machine, characterized in that it comprises two or more stores (2, 2', 2") containing the die-cut corrugated cardboard sheets (F) positioned laterally with respect to or above an initial portion of the conveyor (1) or auxiliary conveyor means associated therewith, and in that it comprises cyclical first transfer means (5, 505) for extracting respective die-cut corrugated cardboard sheets (F) from each of the stores (2, 2', 2") and for feeding them in head to tail arrangement and in phase on to the conveyor which is thus cyclically resupplied with two or more die-cut corrugated cardboard sheets at a time, in order to provide ample opportunity for adaptation to the production requirements of the continuous packaging machine which it serves, while also decreasing the operating frequency of the cyclical first transfer means (5, 505) and consequently increasing the load capacity and overall autonomy of operation of the stores (2, 2', 2").
