  • Apparatus for applying liquid to a yarn sheet
    Patent number: 5683511
    Abstract: An apparatus for applying a liquid to threads of a yarn sheet. The apparatus comprises multiple thread wetting elements, each of which has at least one thread guide groove for each thread. In the thread guide groove the thread travels with the liquid and each thread guide groove has one associated liquid feed bore or groove for supplying the liquid to the thread guide groove. The liquid feed bore or groove terminates in the thread guide groove. There is a liquid distributor which is implemented as a support to which the thread wetting elements are attached and which supplies liquid feed to each liquid bore or groove. The separation of adjacent thread guide grooves is 2 to 30 mm, and adjacent thread guide grooves are different distances from the liquid distributor such that the thread guide grooves are offset in an alternating manner.
