Abstract
Method and means for providing assemblages of fully opened and combed fibers for intimate blending with other staple fibers of a diverse type are disclosed, wherein combed tufts detached from preceding and succeeding tufts are moved in an air stream under subatmospheric pressure to a collection chamber. Movement by such an air stream assures that the parallelized fibers of the tuft are not disturbed but remain in a fully opened and combed condition for subsequent intimate blending. This method and means assure that the fibers are not bent, compressed or otherwise changed from their fully opened and combed state.
Claims15
Improved means for providing fully opened, combed, discrete and non-condensed assemblages of staple fibers for subsequent blending in admixture with other such assemblages of staple fibers of diverse type thereto, then to produce intimate blends of such fibers of diverse types and, upon yet further processing, elongate strands or yarns which have uniquely uniform admixture compositions, said means comprising:
- a. separating and combing means
- for separating a discrete tuft of fibers from a mass thereof and
- for combing said tuft to remove impurities, foreign matter and immature fibers therefrom and to align its contituent fibers into an orientation substantially axially parallel one another while maintaining the same in a substantially non-condensed state;
- b. fiber tuft engaging, advancing and disengaging means
- for engaging said tuft as a discrete entity in a substantially non-condensed state,
- for advancing said fully opened, combed, discrete, non-condensed tuft in a direction substantially parallel to that of the axial orientation of its constituent fibers, and then
- for disengaging said tuft as a discrete entity;
- and
- c. fiber tuft receiving, conveying and collecting means
- for receiving said disengaged combed tuft as a discrete entity and in a substantially non-condensed state, and like preceding and succeeding ones thereof, individually as discrete entities,
- for conveying said tufts as discrete entities while maintaining said tufts in a substantially non-condensed state during said conveying, and
- for collecting said conveyed, non-condensed tufts as discrete entities;
- and
- d. wherein said fiber tuft receiving, conveying and collecting means includes means for providing currents of air to receive said tufts disengaged by said disengaging means, to convey said received tufts to a collection chamber and there to collect said conveyed tufts in a substantially non-condensed state.
An improved method for providing fully opened, combed, discrete and non-condensed assemblages of staple fibers for subsequent blending in admixture with other such assemblages of staple fibers of a diverse type thereto, to produce intimate blends of such fibers of diverse types upon yet further processing into elongate strands or yarns which have uniquely uniform admixture compositions, comprising the steps of
- a. separating a discrete tuft of staple fibers from a mass thereof;
- b. combing said tuft in order to remove therefrom impurities, foreign matter and immature fibers and in order to align its constituent fibers into an orientation substantially axially parallel one another and in a fully opened substantially non-condensed state;
- c. engaging, advancing and releasing said fully opened, combed, non-condensed tuft in order to engage said tuft, to advance said tuft in a direction substantially parallel to that of the axial orientation of its constituent fibers, and then to disengage said discrete combed tuft;
- and
- d. receiving, conveying and collecting said disengaged combed tuft and like preceding and succeeding ones thereof, individually as discrete entities, while maintaining said tufts in a substantially non-condensed state during said receiving, said conveying and said collecting.
