Crosslapper and web drafter round off the further processing possibilities of fiber webs for the various applications.
To produce particularly wide or thick webs, the crosslapper precisely folds the web and lays it down in several layers at high speed - depending on work width more than 160 m per minute. Numerous variations in terms of machine widths fleece width and fleece height allow custom-made solutions for different line configurations.
The design of the latest generation of crosslappers is dedicated to energy efficiency: The systematic reduction of the moving machine masses and rolls made of carbon fibre reinforced plastic (CFRP) lead to reduced acceleration and braking loads. Furthermore, the AC servo motors work with energy recovery.
To ensure a homogeneous web quality, a special software continuously optimises the surface weight of the web.
With up to eight drafting zones, the web drafter sets standards during material drafting. This applies especially to line speed: It increases – fiber-oriented in machine direction – by up to 30 % when processing lightweight products. The web drafter is available in working widths up to 9,000 mm.
