Abstract: A pallet wrapping system with at least two guides sets configured to narrow the width of stretch film to form a banded edge on the stretch film. A plurality of rollers is positioned adjacent to the plurality of guides to facilitate passing the stretch film through the plurality of guides. A first roll of stretch film positioned to pass stretch film to the first set of guides, and a second roll of stretch film positioned to receive banded stretch film from the first set of guides, layer the banded stretch film onto unbanded stretch film to form an unbanded composite stretch film, and then pass the unbanded composite stretch film to the second set of guides to form a banded composite stretch film having a banded first ply with a width equal to the first width and a banded second ply with a width equal to the second width.

Abstract: A method of wrapping a palletized load includes providing an apparatus with a first wrapping system and a second wrapping system, banding a top edge and bottom edge of stretch film from each of the first wrapping system and the second wrapping system, overlapping the stretch film from the first wrapping system with the stretch film from the second wrapping system to create a composite stretch film, and wrapping the composite stretch film around the palletized load. The edges of the stretch film may be banded by passing the stretch film through a set of adjustment arms. The composite stretch film may have a plurality of sections, where each section is separated from adjacent section by a banded border, a first section and third section each has one layer of stretch film, and a second section between the first section and third section has two layers of stretch film.

Abstract: A monitoring system for wrapping a pallet with a pallet wrapping system, at least two encoders, and a control box. The pallet wrapping system has a spool that dispenses stretch film and a pre-stretch machine operably coupled to the pallet wrapping system and configured to elongate the stretch film. The at least two encoders are affixed to the pre-stretch machine. A first of the at least two encoders is configured to measure a length of stretch film entering the pre-stretch machine and a second is configured to measure a length of stretch film exiting the pre-stretch machine. The control box is communicatively coupled to the at least two encoders and configured to collect data regarding the pallet wrapping system and transmit the data over a wireless connection to a central processor configured to gather the data.

Abstract: A pallet wrapping system with a pre-stretch carriage and at least two encoders. The pre-stretch carriage is configured to pre-stretch stretch film and has at least two stretch rollers and a hinged door. The at least two stretch rollers includes a first stretch roller with an outer surface that moves at a first speed and a second stretch roller with an outer surface that moves at a second speed higher than the first speed. The door provides access to the stretch rollers when in an open position and entraps the stretch film between the stretch rollers and the door when in a closed position. The encoders are mounted on the door. Each of the encoders is configured to contact the stretch film on the outer surface of one of the stretch rollers and measure a length of stretch film passing over that stretch roller.

Abstract: 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.
