Applications
The SOMATEC ATW-IG processes particularly wide webs and heavy rolls in large-format applications — for flooring, wide technical textiles and large-format packaging films.
Flooring production — Heavy PVC flooring (LVT, vinyl), heterogeneous flooring and carrier webs
Roofing membranes & construction films — Heavy bitumen sheets, vapor barriers and sealing films
Artificial leather production — Heavy PVC and PU artificial leather webs
Technical textiles — Heavy geotextiles, reinforcement fabrics and coated textiles
Film converting — Thick composite films, heavy packaging films and technical films
Nonwoven processing — Heavy nonwovens and filtration materials
Automotive — Interior trim materials and technical composite films
Paper and board processing — Heavy paper rolls in coating and lamination lines
Why the ATW-IG?
The ATW-IG is the large-format variant of the ATW series with integrated winding shaft extraction. Roll diameters up to 2,400 mm, roll weights up to 2,500 kg and working widths up to 4,000 mm make it the first choice for nonwoven and glass fleece production. The integrated support roller ensures perfect winding quality even with the largest rolls.
Typical Configurations
Glass fleece production: ATW-IG with support roller and integrated winding shaft extraction for roll diameters up to 2,400 mm
Nonwoven line: ATW-IG with TAC system for automatic roll change at full speed and automatic finished roll handling
Large-format film production: SOMATEC unwinder + ATW-IG winder for working widths up to 4,000 mm
