Abstract
Various embodiments of the present disclosure provide a stretch-hood machine and method of operating a stretch-hood machine to perforate tubular film and wrap an item with the tubular film. The method includes drawing tubular film from a roll of film and perforating the tubular film after the tubular film has been drawn from the roll of film so as to form perforations arranged along a length of the tubular film. Using reefing devices, the tubular film is lowered around the item to wrap the item within an interior of the tubular film.

A method of operating a stretch-hood machine to wrap an item with tubular film, the method comprising:
- drawing tubular film from a roll of film;
- perforating the tubular film after the tubular film has been drawn from the roll of film so as to form perforations arranged along a length of the tubular film;
- reefing the tubular film onto reefing fingers of a plurality of reefing devices;
- and
- lowering the reefing devices around the item to wrap the item within an interior of the tubular film.
A stretch-hood machine comprising:
- a machine frame;
- a wrapping carriage movable relative to the machine frame between upper and lower positions;
- a plurality of reefing devices supported by the wrapping carriage and configured to reef a segment of tubular film, stretch the segment of tubular film, and unreef the segment of tubular film;
- a film-supply assembly configured to draw tubular film from a roll of film, cut the tubular film 40 from the roll to form the segment of tubular film, and direct the segment of tubular film to the reefing devices;
- and
- a perforator configured to form perforations arranged along a length of the tubular film after the tubular film is drawn from the roll and before the reefing devices reef the segment of tubular film.
