Abstract
A device and a method for manufacturing a synthetic yarn, in which at least two yarn plugs (1), (2), (3) are produced by texturing, are placed in a first zone (A) on the cooling surface (6c) of a rotating cooling drum (6), moved to a second zone (B) and form more than one winding (I),(II), in which the yarn plugs are kept in the second zone (B) by a gas stream (FB) on the cooling surface (6c), and in which no gas stream or a less powerful gas stream is generated in an intermediate zone (C) in order to prevent the yarn plugs (1), (2), (3) from leaving the second zone (B).
Claims18
A device for manufacturing crimped textile yarn, comprising:
- a texturing unit provided to produce at least two yarn plugs from synthetic material,
- a rotatable cooling drum with a cooling surface for cooling the yarn plugs supplied from the texturing unit, and
- a gas stream generator provided to generate a gas stream to keep the yarn plugs on the cooling surface,
- wherein the device is configured:
- to place the supplied yarn plugs next to each other in a first zone of the cooling surface on the rotating cooling drum, so that they are carried along running alongside each other on the cooling surface,
- to move the yarn plugs running alongside each other laterally to a second zone of the cooling surface during their first turn on the cooling drum, so that the supplied yarn plugs are placed on the cooling surface at an intermediate distance from the yarn plugs running alongside each other which have been moved to the second zone, and
- to lead the yarn plugs away from the cooling drum for their further treatment after forming more than one winding of yarn plugs running alongside each other on the cooling drum,
- wherein the gas stream generator is configured to generate a gas stream in the second zone of the cooling surface, so that the yarn plugs in this second zone are kept on the cooling surface, and either (A) not to generate a gas stream in an intermediate zone of the cooling surface, situated between the first and the second zone, or (B) to generate a gas stream which is less powerful in the intermediate zone than in the second zone, in order to prevent interference between the yarn plugs in the second zone and the yarn plugs in the first zone.
A method for manufacturing crimped textile yarn, comprising:
- producing at least two yarn plugs from synthetic material in a texturing unit,
- placing the yarn plugs in a first zone on a cooling surface of a rotating cooling drum, so that they are carried along running alongside each other on the cooling surface,
- moving the yarn plugs running alongside each other laterally to a second zone on the cooling surface during their first turn on the cooling drum,
- keeping the yarn plugs on the cooling surface by means of a gas stream, and
- leading the yarn plugs running alongside each other away from the cooling drum for further treatment after having formed more than one winding,
- wherein the yarn plugs in the second zone are kept on the cooling surface by a gas stream, and either (A) no gas stream is generated in an intermediate zone of the cooling surface, situated between the first and the second zone, or (B) a gas stream is generated which is less powerful in the intermediate zone than in the second zone, in order to prevent interference between the yarn plugs in the second zone and the yarn plugs in the first zone.
