METHOD AND APPARATUS FOR TREATING STRANDS WITH PULVERULENT MATERIAL

摘要

Method for treating strands comprising filaments with a pulverulent processing medium, wherein the strands are spread and the spread strands thus obtained are then passed into a processing chamber, wherein the pulverulent processing medium, as a powder/fluid, preferably powder/gas mixture, at the start of the processing chamber, is passed over the entire width of the spread strands, at a velocity which is at least as high as the velocity of the spread strands, in a direction which runs parallel to the direction of movement of the spread strands or at an angle of at most 60 DEG with that parallel direction towards the spread strands. An apparatus suitable for implementing the above method comprises one or more members for spreading the strands and a chamber in which the processing takes place.
