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

摘要

It is a device is known, in which the water needling on an endless belt for voluminous fleece arriving between the needling drum and the belt and at the same time compressed by a first water curtain from the nozzle beam is wetted, whose water jets first of all the endless belt and then through the fiber web and finally the needling drum. In this case, this first endless belt a second above, which run conically toward one another in the working area and in so doing, the precompressed fiber web to be supplied to the needling drum. The two endless belts with of the fiber web by means of two rollers are pressed against the needling drum and at the same time, due to a between the closely associated rollers are wetted with these water jets arranged nozzle beam. The network point is not in the pressing region of the two endless belts, but in the direction of transport behind the pressing region of the fiber web, around which a continuous belt of the fluid adhering fibers and at the same time the fiber web to the needling drum to deflect without pulling.
