Abstract
A water needling device has a housing having an intake side and defining a generally horizontal transport direction extending downstream from the intake side. A support in the housing has an upwardly directed foraminous support face. Upstream and downstream reversible winders in the housing spaced apart in the direction flank a plurality of rollers. A textile web passesin the housing along a path starting at the intake, extending over the support face and the rollers, and then downstream out of the housing. A nozzle beam is directed downward at the surface to consolidate the web as it passes over the foraminous face. A threading-in conveyor strand secured to the winders and having a gripper attachable to the textile web extends over at least some of the rollers. This strand is attached at its ends to reversible winders.
