If you laminate knitted stretchable fabrics, you need the laminating machine to be equipped with knitted fabric spreader, opener, centering, tension control and many other devcies specially designed for laminating knitted fabrics. Film openers are different from fabric openers. Different raw materials might need different rewinding devices as well.​
