Apparatus for the dyeing of yarn hanks in short bath and the drying thereof

摘要

In a casing or case (1) for the dyeing and drying, a rotor (9, 12, 16) with horizontal axis can be driven at differentiated speeds and has a central manifold body (14) from which horizontal hollow arms (18) project from opposite sides, said arms (18) being shaped to bear the hanks and having perforated walls; a circuit (12, 14, 18) of air under forced circulation feeds said manifold (14), and causes discharge of air from perforated walls to make same air invest the yarn hanks fitted on and supported by said arms (18); from the bottom (1A) of the casing the liquid is driven to invest the hanks yarn.
