Abstract (en)
[origin: WO2020231357A1] The invention is an ultrasonic welded bag production system for producing bellow bags or sacks of woven or nonwoven technical or non-technical fabrics suitable for ultrasonic welding (combining) or polypropylene (PR) comprising of an inlet unit (11), a puller drive mechanism (14), a forming unit (15), a length combining station (16), a length cutting unit (18), and a bellowing station (10) from which the side bellows and bottom bellows are opened, a bellows folding station (22) that allows the bag to be folded inwardly from the side and bottom bellows surfaces, and an ironing and stacking station (23) to reduce the volume of the bag.
