A method of wrapping a palletized load includes forming at least two composite stretch films, wrapping each of the composite stretch films around the palletized load, and leaving a gap between the first composite stretch film and the second composite stretch film as the composite stretch films are wrapped around the palletized load. Forming the composite stretch films includes narrowing stretch film from a first spool to create a first banded stretch film with a first width, narrowing stretch film from a second spool to create a second banded stretch film with a second width smaller than the first width, and overlaying the second banded stretch film on the first banded stretch film, with the second banded stretch film positioned between the top edge and bottom edges of the first banded stretch film. The gap may have a width that is equal to or larger than the first width.

Disclosed is a method for arranging an edge-protection device on a package. For this purpose, an arranging device is moved from a starting position in the direction of the package. The package edge is sensed by way of a first or a second sensor. Which sensor is to be used is determined by a controller. To this end, the latter checks whether one of the sensors is arranged above the package top side. Also disclosed is an arranging device, which is used in the abovementioned method.

A wrapping machine for making a composed palletized load made by a plurality of partial palletized loads wrapped with a plastic film, comprises a first operating station to individually and separately wrap the partial palletized loads with the film, a conveyor assembly to move along an advancing direction the partial palletized loads inside, towards and outside from the first operating station, a second operating station to arrange the plurality of partial palletized loads in a grouped configuration, in which they are adjacent and placed side by side, and then joint the plurality of partial palletized loads by an adhesive film in order to make the composed palletized load.

A machine for unwinding and rewinding a covering tape (800) includes a first support shaft to coaxially receive a reel of covering tape, a second support shaft, parallel to and distanced from the first support shaft, which is adapted to coaxially receive a tubular support, a motor adapted to put the second support shaft in rotation around its own axis, a plurality of contrast rollers arranged around the second support shaft and oriented parallel thereto, and a movement apparatus adapted to move the contrast rollers towards and away from the axis of the second support shaft.

A machine for stabilising palletised loads includes a functional arrangement, a first movement apparatus generating relative motion about a revolution axis around the palletised load, a second movement apparatus generating relative translation motion of the functional arrangement with respect to the palletised load in a direction parallel to the revolution axis. The functional arrangement includes a support shaft, a motorised drive roller, a contrast roller, and actuator members to create relative movement between the drive roller and the contrast roller in transversal direction with respect to the respective rotation axes between a distanced configuration, in which a gap is defined between the drive roller and the contrast roller to be crossed with clearance by the covering tape unwinding from the reel, and a neared configuration, in which the drive and contrast rollers clamp the covering tape, wherein the support shaft and the contrast and/or drive rollers are mounted on the functional arrangement and oriented in the same direction.

Control of a wrapping apparatus is facilitated by enabling an operator to input a load containment force requirement and/or a minimum number of layers of packaging material to be applied to a load, with a wrap control system automatically determining wrap force and other parameters required to meet user input requirements and/or parameters to minimize the expertise required of an operator and to provide more consistent and reliable wrapping of loads. In addition, a wrapping apparatus may be controlled to apply at least a minimum number of layers of packaging material to a load throughout a contiguous region thereof.

The present disclosure is directed to the packaging of metal thin films deposited on polymeric substrates. The packaging method prevents deleterious change of surface energy/water contact angle as a function of time for metal thin films such as rolls, coils, sheets or strips of sputtered or vacuum deposited metal thin films. Methods and kits directed toward a unique packaging and storage scheme are also disclosed. This results in maintenance of the metal film's hydrophilicity and surface energy for extended periods of time.

Disclosed are packaged fibrous material bales and methods for packaging fibrous materials such as cellulose acetate tow bales. The packaged fibrous material bale may comprise a compressed fibrous material enclosed in packaging. The packaging may comprise an upper sheet and a lower sheet comprising a tab. After the residual forces in the packaged bale have equilibrated following pressing, greater than 99% of the surface area of the bale is enclosed by the packaging.
