Embodiment Construction

[0027] figure 1 A godet 1 is shown in section. The godet 1 essentially comprises a heatable godet housing 2 , which is connected to a shaft 10 mounted rotatably in a bearing 11 . On the outer circumference of the godet housing 2, the filaments can be guided in the guide region 3 in the form of half turns or in combination with a second godet or bypass roller in the form of multiple turns. On the one hand, a pulling force can be exerted on the filament due to friction, and on the other hand, the heat of the godet housing can be transferred to the filament by contact with the godet housing.

[0028] The filaments can be guided in an axially extending guide region 3 . The godet is heated in an axially extending heating zone 5 . Obviously, the practically usable guiding area is limited to the heating area 5 .

[0029] The bracket 12 in which the bearing 11 is fixed carries the heating coil 9 and the stator 6 at the same time. The heating coil 9 is fed with a high-frequency al...

Abstract

The invention relates to a driven galette which can be heated inductively and to a method for operating a galette which can be heated inductively. In order to save installation space for the galette, both heating coils for heating and stator coils for driving the galette are provided within the galette cover on a common holding device, wherein the stator coils are arranged within the heating region. Here, a plurality of coils or the windings of the coils can be arranged in an alternating manner. There is likewise provision for the same coils to be provided for heating and electric-motor drive.

Description

technical field [0001] The invention relates to a godet / godette according to the preamble of claim 1 . Background technique [0002] A drivable, inductively heatable godet is known, for example, from EP 0 511 549 B1. The godets are used in filament processing plants in order to guide and transport the filaments. For this purpose, the godet has a rotatably driven housing, which can guide the yarn in half turns or, in combination with a second godet or bypass roller, in multiple turns. Based on the Eytelweinschen formula, the force can be transmitted to the filament. For this purpose, the godet is driven by means of an electric motor. [0003] In order to obtain defined physical properties of the filament, the godet housing is additionally heated inductively. For this purpose, induction coils are arranged in the godet housing, which generate a high-frequency electromagnetic alternating field. This induces godet eddy currents in the godet housing, which heat the godet hous...
