Verfahren und Vorrichtung zum Herstellen einer wiederverschliessbaren Verpackung.

摘要

A method and an apparatus for applying a reclosable profile element and a tear strip element to a packaging film is disclosed. Packaging film (15) is formed into a tubular form about a forming tube (22). The tubular shaped packaging film (15) is advanced along the length of the forming tube (22) and over a product fill tube (24) having an outer perimeter less than the outer perimeter of the forming tube (22). The packaging film (15) is deformed to conform to the outer perimeter of the product fill tube (24). Excess packaging film, made available due to the differences in outer perimeters of the forming tube (22) and product fill tube (24), is formed into a loop. A reclosable profile element (30) is guided into the loop and adhered to the inner surface of the loop. A tear strip (31) is also provided which may be adhered to the packaging film prior to said film into a tubular shape about said forming tube, or may be guided into the loop of said film.
