Device for the hydrodynamic entwining of the fibers from a fiber web

摘要

It is a device is known, in which the on the upper side of an endless belt for water needling is voluminous fleece arriving between a needling drum and the belt and at the same time compressed by a first water curtain from a nozzle beam is wetted, whose water jets first of all the endless belt and then through the fiber web and finally the needling drum. According to the invention, now the unstiffened fleece on the underside of an endless belt is held by means of a transported and tangentially to a needling drum, is arranged below the endless band. In this way, the gravity influences the transfer of fiber web of the endless belt to the needling drum causes.
