  • Patent number: 5243840
    Abstract: A textile treatment apparatus for an endless textile hank is comprised of a vessel having a dwell or treatment zone at a lower portion thereof and an upper acceleration or feed zone above said dwell zone. A blower assembly mounted in the roof the vessel above the acceleration zone advances the hank by subjecting said to a purely gaseous stream so as to remove the hank from the exit of the dwell zone and introduce it into the entrance of such zone. Treatment nozzles located at the entry to the dwell zone saturate the hank and aid in guiding it unimpeded into the dwell zone. The location of the blower assembly or assemblies at the upper extremity of the vessel facilitate servicing and minimize fluid introduction into the gaseous feed stream.

  • Patent number: 4015452
    Abstract: This invention relates to an apparatus for interrupting the rotary movement of a drive roller for feeding a textile web and comprises a pivoted lever having a frame at one end with an opening through which passes the web driven by the roller. Positioned beneath the opening in the frame is a ring nozzle supplied with liquid under pressure to advance the web passing through the opening in the frame through a guide tube associated with the nozzle. A magnetic switch is provided in circuit with the drive means for the roller to effect stoppage of the rotation of the roller when the switch is actuated, a linkage being connected between the lever and the switch to actuate the latter when the lever is pivoted.

  • Patent number: 3982411
    Abstract: A wet treatment device for dyeing textile materials in the form of an endless rope comprising a pressure tank consisting of a horizontal storage portion having one end curved upwardly with a vertical deflection portion rising from such curved end, a driving tube being provided having the mouth end thereof leading into the deflection portion and its other end leading into the other end of said horizontal portion. The rope is advanced continuously, at first in stretched form, through the driving tube by means of jets of treatment liquid, into the other end of the horizontal storage portion in which it floats in loops through the treatment fluid therein in the direction of the deflection portion where it rides over a rotating wheel which guides the rope in stretched form into the mouth of the driving tube.
