Abstract
Pre-stretched films may be used to increase the rate at which loads can be wrapped and to minimize the exertion required when using traditional handheld film. However, the edges of pre-stretched films are easily damaged, which may result in tearing or failure of the film during use. The present disclosure describes devices, systems, and methods for folding the edges of the film, resulting in a film that is less susceptible to damage and easier to use.
Claims14
A method of folding edges of film in-process, said method comprising:
- separating a first idler roll and a second idler roll by a first distance;
- positioning a plurality of folding guides between the first idler roll and the second idler roll;
- separating adjacent sections of film and inducing two folds with each folding guide, thereby causing an edge of each section of film to turn under 180° and cling to a bottom surface of the section of film;
- and
- moving the adjacent sections of film from the folding guides to the second idler roll.
A method of producing folded edges in a film in-process, said method comprising the steps of:
- separating a first idler roll from a second idler roll by a first distance;
- positioning at least one folding guide between the first idler roll and the second idler roll, and
- separating adjacent sections of film and inducing two folds with the folding guide, thereby causing an edge of each section of film to turn under 180° and cling to a bottom surface of the section of film.
