Abstract
Pallet roping and wrapping machines having a plurality of spools of stretch film supported on one or more spools and guides that form ropes of stretch film without cutting. Specific implementations of guides include guides formed or rings and rollers. Positions of guides may be adjustable. A primary roll of stretch film may be positionally coupled to a primary spool core, and a plurality of secondary rolls of stretch film may be positionally coupled to one or more secondary spool cores. The wrapping machines may include a plurality of guides positioned to narrow the stretch film from the plurality of secondary rolls to form a plurality of ropes fully overlapping a web of the primary roll of stretch film when wrapped around a palletized load.
Claims18
An apparatus for securing a palletized load, comprising:
- a primary roll of stretch film supported by a first spool support member;
- at least one secondary roll of stretch film supported by at least a second spool support member;
- and
- at least two sets of guides each comprising a guide width less than a width of the at least one secondary roll, each of the guides being positioned to receive a different portion of stretch film from the at least one secondary roll through the respective guide, narrow the portion received to form a rope that is narrower than a width of stretch film from the primary roll of stretch film, and position each of the two narrower ropes on the wider stretch film from the primary roll such that the two narrower ropes do not overlap each other and such that each of the two narrower ropes is positioned within the width of the wider stretch film formed by the primary roll before the stretch film from the primary roll and the stretch film from the at least one secondary roll is together stretched in a pre-stretch carriage before applying the stretch film to an item to be wrapped.
A tamper deterring apparatus for securing a palletized load, comprising:
- a primary roll of stretch film supported by a first spool support member;
- at least two secondary rolls of stretch film colored differently than the primary roll of stretch film and supported by a second spool support member;
- at least two sets of guides each comprising a guide width less than a width of each of the at least two secondary rolls and positioned to receive one of the at least two secondary rolls through the respective guide, narrow the respective secondary roll to form a rope, and position the rope such that the rope is positioned within a width of and fully overlaps a web formed by the primary roll as the primary roll and the secondary roll are wrapped around a palletized load.
An apparatus for securing a palletized load, comprising:
- a primary roll of stretch film supported by a first spool support member;
- at least one secondary roll of stretch film supported by at least a second spool support member;
- and
- at least two guides having a guide width between them less than a width of the at least one secondary roll of stretch film, the guides being positioned to receive the stretch film from the at least one secondary roll, narrow it to form a rope narrower than a width of the stretch film from the primary roll of stretch film and guide the narrower rope over a web from the wider primary roll to position it fully within the width of the primary roll before the stretch film from the primary roll and the stretch film from the at least one secondary roll are together stretched in a pre-stretch carriage and before applying the stretch film to an item to be wrapped.
