Abstract
Method and apparatus for texturing yarns that encompasses, after stopping the moving yarns during normal operations, increasing the opening size of the outlet of the stuffer box, and injecting a fluid through the interior of the stuffer box. The fluid entrains some of the yarns remaining within the interior of the stuffer box to move at least a portion of the yarns outside of the stuffer box.
Claims43
A method for texturing yarns, comprising:
- a. moving the yarns through an interior of a stuffer box, the stuffer box having an inlet through which the yarns enter the interior and an outlet through which the yarns exit the interior, the outlet having an opening size partially defined by at least one movable flapper door;
- b. stopping the moving yarns so that some of the yarns remain within the interior of the stuffer box;
- c. increasing the opening size of the outlet of the stuffer box by moving at least one flapper door;
- and
- d. injecting a fluid through a portion of the interior of the stuffer box, the fluid entraining some of the yarns remaining within the interior of the stuffer box to move at least a portion of the yarns out of the interior of the stuffer box.

A method for texturing yarns, comprising the steps of:
- a. moving the yarns through an interior of a stuffer box, the stuffer box having an inlet through which the yarns enter the interior and an outlet through which the yarns exit the interior, the outlet having an opening size partially defined by at least one movable flapper door;
- b. stopping the moving yarns so that some of the yarns remain within the interior of the stuffer box;
- c. after the stopping step, increasing the opening size of the outlet of the stuffer box by moving at least one flapper door;
- d. injecting a fluid through a portion of the interior of the stuffer box, the fluid entraining some of the yarns remaining within the interior of the stuffer box to move at least a portion of the yarns out of the interior of the stuffer box;
- and
- e. after the injecting step, stopping the injection of the fluid.

A texturizing apparatus, comprising:
- a. a stuffer box having at least one movable flapper door, an interior, an inlet of a size to allow a plurality of yarns to enter the interior, and an outlet through which the yarns may exit the interior, the outlet having an opening size partially defined by the at least one movable flapper door;
- b. at least one actuator, each actuator coupled to one respective flapper door for moving that flapper door between an open position and a closed position, in which the open position widens the opening size of the outlet compared with the closed position;
- c. at least one conduit, each conduit having an influent end, an effluent end, and a body extending between the influent and effluent ends, wherein the effluent end is in fluid communication with the interior of the stuffer box so that pressurized fluid entering the influent end of the conduit travels through the body and exits out of the effluent end into the interior of the stuffer box.
A texturizing apparatus, comprising:
- a. a plurality of yarns;
- b. a stuffer box having at least one movable flapper door, an interior, an inlet of a size to allow the plurality of yarns to enter the interior, and an outlet through which the yarns may exit the interior, the outlet having an opening size partially defined by the at least one movable flapper door;
- c. at least one actuator, each actuator coupled to one respective flapper door for moving that flapper door between an open position and a closed position, in which the open position widens the opening size of the outlet compared with the closed position;
- and
- d. at least one conduit, each conduit having an influent end, an effluent end, and a body extending between the influent and effluent ends, wherein the effluent end is in fluid communication with the interior of the stuffer box so that pressurized fluid entering the influent end of the conduit travels through the body and exits out of the effluent end into the interior of the stuffer box to interface with the yarns therein.

- b. means for moving the flapper door between an open position and a closed position, in which the open position widens the opening size of the outlet compared with the closed position;
- and
- c. at least one conduit, each conduit having an influent end, an effluent end, and a body extending between the influent and effluent ends, wherein the effluent end is in fluid communication with the interior of the stuffer box so that pressurized fluid entering the influent end of the conduit travels through the body and exits out of the effluent end into the interior of the stuffer box to interface with the yarns therein.
