Abstract
Pallet roping and wrapping machines having a plurality of spools of stretch film supported on a single spool and guides that form ropes of stretch film without cutting. Specific implementations of guides include guides formed of rings and rollers. Positions of guides may be adjustable. A first roll of stretch film may be used with a second roll of stretch film, where the second roll of stretch film is narrowed into ropes and combined with a web from the first roll of stretch film. The combination of film from the first roll of stretch film and narrowed film from the second roll of stretch film may be pre-stretched prior to be applied to a load.
Claims17
An apparatus for securing a palletized load, the apparatus comprising:
- a first roll of stretch film supported by a first spool support member;
- at least two second rolls of stretch film positionally coupled to a common spool core such that the at least two second rolls of stretch film unroll at substantially the same rate, the common spool core being supported by a second spool support member;
- at least two sets of guides positioned adjacent to the second spool support member, each set of guides having a guide width less than a width of each of the at least two second rolls, each of the at least two second rolls of stretch film positioned to pass through a different set of the at least two sets of guides;
- wherein two portions of a first path of the stretch film from the first roll of stretch film to a load to be secured are overlapped by two second paths of the stretch film from the at least two second rolls of stretch film to the load to be secured after the stretch film from the at least two second rolls of stretch film pass through the at least two sets of guides such that the stretch film from the at least two second rolls of stretch film is applied to the load simultaneous with the stretch film from the first roll of stretch film.
A method of securing a palletized load comprising:
- dispensing a first stretch film from a first roll of stretch film supported on a first support member;
- dispensing at substantially the same rate at least two second stretch films from at least two second rolls of stretch film positionally coupled to a common spool core supported on a second support member;
- narrowing a band width of each of the at least two second stretch films with two sets of guides;
- overlapping two portions of the first stretch film with the two narrowed second stretch films;
- and
- simultaneously applying the overlapped first stretch film and second stretch film to a load to be secured after they have been overlapped.
An apparatus for securing a palletized load, the apparatus comprising:
- a first roll of stretch film supported by a first spool support member;
- a plurality of separate rolls of stretch film on a common spool core, the spool core being positionally coupled to each of the plurality of rolls such that the rolls unroll at substantially the same rate, the spool core being supported by a second spool support member;
- wherein the first roll, plurality of separate rolls and a pre-stretch carriage are mutually positioned such that the pre-stretch carriage simultaneously receives first stretch film from the first roll and second stretch film from the plurality of separate rolls in an overlapped manner and simultaneously pre-stretches the first and second stretch films prior to simultaneously applying the overlapped first and second stretch films to a load.
