Abstract
Various embodiments of the present disclosure provide systems including stretch-hood machines configured to vertically and horizontally apply tubular stretch film to loads of goods and to methods for wrapping loads of goods with multiple segments of tubular stretch film.
Claims23
A wrapping system comprising:
- a stretch-hood machine comprising:
- a machine frame defining a wrapping area having an infeed area and an outfeed area;
- a wrapping carriage vertically movable relative to the machine frame between upper and lower positions and rotatable relative to the machine frame about a generally horizontal axis between first and second rotational positions;
- one or more actuators operably connected to the wrapping carriage and configured to move the wrapping carriage between its upper and lower positions and between its first and second rotational positions;
- and
- multiple reefing devices supported by the wrapping carriage.

A method of wrapping a load with tubular stretch film, the method comprising:
- with a wrapping carriage of a stretch-hood machine in a first rotational position relative to a machine frame of the stretch-hood machine, reefing a segment of tubular stretch film onto multiple reefing fingers supported by the wrapping carriage;
- after the segment of tubular film has been reefed onto the reefing fingers, rotating the wrapping carriage relative to the machine frame in a first rotational direction about a generally horizontal axis to a second rotational position that is transverse to the first rotational position;
- lowering the wrapping carriage;
- moving a load relative to the wrapping carriage in a first direction and into contact with the segment of tubular film;
- and
- while continuing to move the load relative to the wrapping carriage in the first direction, unreefing the segment of tubular film from the reefing devices and onto the load.
