Abstract
A cooling apparatus and method for cooling an advancing yarn, which includes an elongate cooling rail along which the advancing yarn is guided. At each end of the cooling rail, the yarn and the cooling rail are reciprocated relative to each other in a direction transverse to the direction of the advancing yarn, so that the yarn sweeps over the cooling surface of the cooling rail, thus facilitating the removal of a possibly developing condensate.
Claims19
An apparatus for cooling an advancing yarn comprising:
- an elongate cooling rail which defines a longitudinal direction and opposite ends,
- means for guiding the advancing yarn longitudinally along the cooling rail, and
- means for creating back and forth relative movement in a direction transverse to the longitudinal direction between the yarn and the cooling rail adjacent each of the opposite ends of the cooling rail and such that the relative movements adjacent the opposite ends of the cooling rail are out of phase.
A method for cooling an advancing yarn comprising the steps of:
- providing an elongate cooling rail which defines a longitudinal direction and opposite ends,
- guiding the advancing yarn longitudinally along the cooling rail, and while
- creating back and forth relative movement in a direction transverse to the longitudinal direction between the yarn and the cooling rail adjacent each of the opposite ends of the cooling rail and such that the relative movements adjacent the opposite ends of the cooling rail are out of phase.
An apparatus for cooling an advancing yarn comprising:
- an elongate cooling rail which defines a longitudinal direction and opposite ends,
- means for guiding the advancing yarn along a stationary path of travel longitudinally along the cooling rail, and
- means for creating back and forth relative movement in a direction transverse to the longitudinal direction between the yarn and the cooling rail adjacent each of the opposite ends of the cooling rail and including means for reciprocating the cooling rail transversely at each of the opposite ends thereof.
