Abstract
Increasingly higher requirements are imposed on the quality and the speed of the production process during the manufacture of nonwovens. It is therefore an object of the invention to provide a process belt for improved nonwoven manufacture. This object is achieved with a process belt for nonwoven or paper manufacture which comprises a device for electrical charging of the process belt.Such a device makes it possible to influence the deposition of nonwoven material on the belt and also to optimally configure the contact between belt and nonwoven material during nonwoven manufacture.In particular, during the transfer of nonwoven material from one belt to another or another installation part, the electrostatic charge assists by repulsion and attraction reactions between nonwoven material and belt.
