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.
Claims13
An apparatus for dyeing a travelling strip having
- a conveying channel for passage of the strip through a predetermined treatment station;
- at least one supply channel having an outlet for supplying a treatment medium to said station in a programmed manner;
- and
- at least one channel downstream of said treatment station relative to the travelling strip and concentric to said conveying channel for supplying compressed air to said treatment station circumferentially of the strip for removing excess treatment medium from the strip.
An apparatus for dyeing a travelling strip comprising
- an elongated channel for conducting the travelling strip through a treatment station;
- a supply channel disposed perpendicularly of said elongated channel and having an outlet at said station for supplying a treatment medium thereto;
- a funnel-shaped annular channel upstream of said station having an outlet at the apex thereof and at said outlet of said supply channel for supplying compressed air to seal said elongated channel upstream of said station against the treatment medium;
- a funnel-shaped annular channel downstream of said station having an outlet at the apex thereof and at said outlet of said supply channel for supplying compressed air to said station;
- and
- an exhaust channel perpendicular to said elongated channel at said treatment station for removing excess treatment material and air from said station, said exhaust channel having an inlet disposed between said outlets of said funnel-shaped annular channels.
An apparatus for dyeing a travelling strip comprising
- a housing having a first channel for conducting the travelling strip through a predetermined treatment station therein, at least one supply channel having an outlet at said treatment station for supplying a treatment medium to said station, at least one channel downstream of said treatment station relative to the travelling strip and concentric to said first channel for supplying compressed air to said station and an exhaust channel in communication with said station for removing excess treatment medium and air therefrom;
- and
- means for supplying the treatment medium to said supply channel at said station to dye a portion of the strip thereat.
