Abstract
The dyeing apparatus effects a programmed dyeing pattern on the travelling strip. This apparatus includes a housing provided with a through channel for passage of the travelling strip through a treatment station in the housing. Treatment medium such as a dye is delivered to the treatment station via a channel perpendicular to the strip. In addition, compressed air is delivered to the treatment station via a funnel-shaped channel downstream of the station to remove excess dye from the yarn and to obtain a clean well-defined dyed area on the strip. A similar funnel-shaped channel upstream of the treatment station serves to seal the elongated channel against the treatment medium. Also, an exhaust channel is provided to remove excess treatment medium and air.
