摘要:A process for producing a tubular film (200a,200b), esp a bottle sleeve label,comprises using a film material (12) wound on a roll (10) with two side regions (16a,16b)and a central region (18). Each of the two side regions of the film is folded upwards in thedirection of movement, and are then folded over and pressed flat onto the centralregion. The film is then welded through, using a hot air, a high frequency, laser or thermalwelding techniques. The arrangement used to produce the tubular film consists of aprefolding station (20), a flattening station (30) and a welding station (60). The latter hasat least two symmetrically arrangeable weld sections. A suction unit removes residualfilm material.
