Abstract
Multiple needling with web guidance on alternate sides is achieved. Either an endless belt and/or a drum performs a carrying function, the belt or drum being arranged so that the fiber web can be associated meanderwise with the other side of a nozzle beam in each case. Transfer from one transport device or unit to another takes place by constant, positive, and non-stretching support of the fiber web, which is sensitive to being stretched.
