Problems solved by technology

Due to the high peripheral speed and the high air flow associated therewith, such a heating device entails high energy losses
On the other hand, it is almost impossible to control in order to adjust the surface temperature of the godet roll to the specified one, and in addition, there is a large heat loss in the edge area of ​​the godet roll due to heat conduction

Embodiment Construction

[0031] A first embodiment of the godet according to the invention is shown in several views in FIGS. 1 and 2 . 1 schematically shows a cross-sectional view, and FIG. 2 schematically shows a front view. If no particular figure is referred to in this regard, the following description applies to both figures.

[0032] The godet has a hollow cylindrical godet housing 1 which is pot-shaped at one end by an end wall 4 . On the side opposite the end wall 4, the godet housing 1 is open. The end wall 4 of the godet housing 1 is connected to a hub 5 which is fixed to rotate on the circumference of the shaft 3 . The shaft 3 is mounted rotatably cantilevered on a support 2 arranged laterally next to the godet housing. Bearings 6.1 and 6.2 are provided on the carrier 2 for this purpose. On the side of the support 2 opposite the godet housing 1 , the shaft is connected to an electric motor 7 . The shaft 3 passes through the motor 7 and has a free end on which a signal transmitter 13 is...

Abstract

The invention relates to a galette for guiding, heating and transporting a thread, said galette comprising a rotating, driveable, hollow cylindrical galette jacket. An induction heating device is provided for heating the galette jacket, said device comprising a plurality of induction coils arranged at a distance from the galette jacket. The aim of the invention is to influence the heating of the galette jacket as directly and instantaneously as possible. To this end, the induction device is arranged outside the galette jacket (1).

Description

technical field [0001] The invention relates to a godet for guiding, heating and transporting filaments according to the preamble of claim 1 . Background technique [0002] Godets of this type are known, for example, from WO 97 / 49265 (=US 5,979,592). [0003] Such godet rolls are used to heat, convey and guide the filaments in spinning plants or textile machines. In this case, the rotating godet shell is heated so that the filaments running on the circumference of the godet shell are heated by contact. For heating, the filament or a plurality of parallel filaments running side by side are preferably guided multiple times in partial windings through the godet housing, wherein the parallel partial windings of the filaments are located in the heated part of the godet housing. laying length. It is essential here in particular that the godet shell has a uniform surface temperature over the entire lay length in order to obtain a defined heating of the filament or filaments. In...
