Abstract
A device is known in which the bulky felt arriving on the top side of an endless belt for water felting is compacted between a felting drum and the belt and at the same time it is wetted by a first water curtain from a nozzle beam, whose water jets first pass through the endless belt and then the fiber web and finally the felting drum. Now, according to the invention, the unconsolidated felt is held against the bottom of an endless belt by means of induced suction and transported, and it is brought up tangentially to a needle felting drum, arranged beneath the endless belt. In this way, the handover of the fiber web from the endless belt to the needle felting drum is accomplished under the influence of gravity.
