The opening station in turn comprising housing means of the pack identifying a housing seating of the pack. The opening station comprises weakening means of a part of the film. The weakening means comprising heating means of a fluid and a first outlet mouth and a second outlet mouth of the heated fluid, said first mouth and said second mouth being, at least in a configuration thereof: operatively connected to said heating means of a fluid; facing towards said housing seating; facing towards an imaginary plane interposed there-between.
Claims10
A method for removing a plastic wrapping film (9) from a pack (10) developing along a longitudinal direction between a first end (94) and a second end (95) comprising a stage of housing the pack (10) in an opening station (2) of the film (9), by placing the pack (10) in contact with at least a first roller (411) and a second roller (412) and positioning the pack (10) with a longitudinal direction thereof parallel to rotation axes of the first roller (411) and the second roller (412), characterised in that:
- it weakens portions of the wrapping film (9) of the pack (10), by directing a heated fluid against a first end (94) and a second end (95) of the pack (10);
- it tears the wrapping film (9) of the pack (10) without blades, by rotating the first roller (411) and the second roller (412) in opposite directions, the stage of tearing the film (9) being at least partly subsequent to or contemporaneous with the stage of weakening portions of the film (9);
- the step of tearing the wrapping film (9) of the pack (10) comprising the rotating of the first roller (411) and of the second roller (412) in two opposite directions for stretching the portion of the film (9) interposed between them.
