摘要

Dye change-over switch arrangement comprises dye change-over switches (2a, 2b, 2c) and a valve block (4) having at least two color channel inlets (5a, 5b, 5c) and a dye channel outlet (6). The dye change-over switches are connected by their dye channels (3) to the dye channel inlets of the valve block. Units are provided for preventing penetration of dye from a dye channel of one change-over switch into a dye channel of a further dye change-over switch. Preferred Features: The dye channel inlets can be opened and closed using valves (7a, 7b, 7c) which are independently controlled. The dye channel inlets and the dye channel outlet are connected to each other within the valve block.
