Abstract
The device comprises: a two-for-one twisting spindle supporting a yarn winding which is twisted or cabled via a second yarn; a mechanism for pulling the yarn in order to cancel the tension resulting from the twisting or cabling operation; a heater for heating the yarn followed by a cooling area; and a mechanism for coiling the yarn. The heater comprises at least one cup-shaped element which is associated with a return guide enabling the yarn to be wound. The cup-shaped element is brought to a specific temperature and is positively driven in a state of rotation.
Claims8
A device for continuous cabling and setting of yarns followed by an additional heat treatment, comprising:
- a double twist or cabling spindle supporting a first yarn, said first yarn being twisted or cabled together with a second yarn to produce a twisted or cabled yarn;
- means for take-up of a yarn in order to cancel out tension resulting from a twisting or cabling operation resulting in the twisted or cabled yarn being in a relaxed state;
- yarn heating means followed by a cooling zone;
- means for winding up the twisted or cabled yarn, wherein
- the heating means comprises at least one heating godet associated with a return guide or roller for allowing a reeving of the twisted or cabled yarn, said godet being brought to a defined temperature and being driven positively in rotation;
- and
- said at least one heating godet receiving the twisted or cabled yarn in the relaxed state from the means for take-up of the yarn.
