Abstract
A yarn to be dyed at intermittent locations is continuously transported at high speed and in stretched condition past a nozzle supplied with dyestuff under pressure, with interposition of one or more rotary shutters such as disks with arrays of apertures of various configurations centered on the axis of rotation. Synchronization between yarn motion and shutter rotation may be achieved by designing the shutter as a grooved pulley or sheave with a frustoconical recess having apertures near the groove bottom through which a yarn entraining the pulley or entrained by it can be sprayed by a nozzle lodged in the recess.
Claims10
A device for intermittently dyeing filamentary material, comprising:
- a spray nozzle connected to a supply of liquid dyestuff under pressure;
- transport means for continuously conveying a filament along a predetermined path past said nozzle;
- and
- shutter means interposed between said nozzle and said path for chopping a jet of dyestuff trained upon the latter by said nozzle, said shutter means including a dished wheel with radially projecting, peripherally spaced sectoral vanes mounted on a shaft for rotation about an axis thereof, said wheel having a concave side partly surrounding said nozzle.
A device for intermittently dyeing filamentary material, comprising:
- a spray nozzle connected to a supply of liquid dyestuff under pressure;
- transport means for continuously conveying a filament along a predetermined path past said nozzle;
- and
- shutter means interposed between said nozzle and said path for chopping a jet of dyestuff trained upon the latter by said nozzle, said shutter means including a sheave with a peripheral V-groove disposed in the path of said filament and mounted on a shaft for rotation about the axis thereof in synchronism with the advance of said filament, said sheave being provided with apertures in a wall of said V-groove close to the bottom thereof on an orbit intersected by the nozzle axis.
