A device for palletizing a plurality of articles and for stabilizing selected ones of the plurality of articles is provided. The device includes at least one load stabilizer and at least one stabilizer applier. The at least one load stabilizer includes a stabilizer sheet and an adhesive layer coupled with the stabilizer sheet. The at least one stabilizer applier receives the at least one load stabilizer and applies the adhesive layer to a select potential shift point of a palletized load.

A method of wrapping bundles is with stretch film from a reel. Bundles include products in transit through a wrapping machine including a wrapping unit having a ring winder which rotatably arranges stretch film around the bundles. During transit through the winding unit, the stretch film is unwound from the reel and passes through a pre-stretching group which generates axial deformation of the film predetermining an elastic return quantity. The axially deformed film interfaces with a vacuum having a vacuum box producing a constant auxiliary tensional stress on the pre-stretched film equal to the head inside the vacuum box. The film is then deposited on the bundles with a constant stress residue at each point of application of the pre-stretched film after adding the constant load generated by the vacuum box, producing bundles completely wrapped with a programmed stress residue.

An orbital stretch wrapping apparatus is provided and includes a base frame, a circular ring mounted on the base frame and rotatable with respect to the base frame about an axis of rotation, a stretch film dispenser mounted on the circular ring and rotatable with the circular ring about the axis of rotation, the stretch film dispenser having a subframe fixed to the circular ring, a roll of stretch film mounted to the subframe and rotatable with respect to the subframe, a first feed roller mounted to the subframe and rotatable with respect to the subframe, a second feed roller mounted to the subframe and rotatable with respect to the subframe, and a brake member connected to the first feed roller and the second feed roller.

A self-propelled wrapping machine movable on a supporting plane to wrap a load with a film has a self-propelled carriage provided with a drive wheel, an upright slidably supporting an unwinding unit provided with a reel of film, an actuator to operate the drive wheel and the unwinding unit along the upright, a control unit to control the actuator, and a scanning device to scan a defined area of the supporting plane to detect a possible obstacle in the area and in the presence of the obstacle to send an obstacle alarm signal to the control unit to stop the actuator. The scanning device is configured to scan a first area of the supporting plane during a wrapping cycle of a load and a second area during a manual maneuvering procedure, the second area being smaller than the first area.

A method and a bale wrapping device for wrapping a bale. The method includes receiving a bale at a bale moving ramp device of the bale wrapping device. The bale on the bale moving ramp device is moved through a bale wrapping frame. The sheet of wrapping material is applied on the bale to wrap the bale as the bale passes through the bale wrapping frame, and a roller on the bale wrapping frame holds a roll of the sheet of wrapping material.

A wrapping machine for wrapping a film around a product includes a supporting frame, a rotating ring rotatably supported by the supporting frame, supporting wheels fixed to the supporting frame to rotatably support the rotating ring, an unwinding unit fixed to the rotating ring, and a drive system to rotate the rotating ring and having a flexible element wrapped around the external peripheral edge of the rotating ring. The external peripheral edge of the rotating ring has first and second annular portions. Each supporting wheel has an annular guide groove to receive and engage the first annular portion. The second annular portion is provided with an annular seat suitable to receive the flexible element and having a second external diameter smaller than a first external diameter of the first annular portion.

A wrapper machine has a coiling station for forming a coil of a flexible article with an elongated shape, a packaging station for wrapping a stretch film around the coil of the flexible article, a transfer unit for transferring the coil of the flexible article from the coiling station to the packaging station where the coil of flexible article is rotated intermittently to be wrapped in a stretch film, and a roll-replacement unit to replace a roll of stretch film mounted in the packaging station.

A machine wrapping bundles with stretch film from a reel with continuous suction includes a ring wrapping machine arranging stretch film around the bundles. The film unwinds from a reel on a rotating ring of the wrapping machine to wrap around bundles, during the passing of the bundles. A pre-stretching group of the stretch film generates an axial deformation of the stretch film. A vacuum box downstream of the pre-stretching group continuously receives the deformed film. The pre-stretching group and vacuum box are arranged on the rotating ring around the bundles. A rotating magnetic track associated with the rotating ring causes a magnetic track wheel/disc to rotate, creating a magnetic transmission having a shaft supported in the pre-stretching group, which actuates a rubber roller on which the film passes. A dynamo connects directly to the magnetic transmission and batteries. A vacuum pump connects to the vacuum box and batteries.
