CA 2334866

The invention relates to a pot spinning device (1) comprising a thread guide (9) which can be moved backwards and forwards and introduced into an opening (8) on the end side of the pot (7) so as to deposit a thread on the inside wall of a spinning pot. In order to improve upon pot spinning devices of this kind, the spinning pot is connected to an electric drive mechanism (10), mounted in magnetic bearings and provided with a gastight housing. Said housing encompasses the spinning pot (7), is open in the area where there is an opening in the end side of the pot and is provided with a seal (19) to seal off the intermediate area (17) between the housing and spinning pot. The housing is also connected to a supply of light-gas via a feed line (18), thereby enabling a light-gas atmosphere to be maintained in the intermediate area.

L'invention concerne un dispositif à filer à gamelle (1)comprenant un guide-fil (2) qui est animé d'un mouvement de va-et-vient et qui peut être introduit dans une ouverture (8) pratiquée à une extrémité du pot en vue de déposer un fil sur la paroi interne d'un pot (7). Pour améliorer un tel dispositif à filer à gamelle, le pot est relié à un entraînement électrique (10), fixé dans des paliers magnétiques et doté d'un boîtier étanche au gaz. Ce boîtier abrite au moins le pot (7). Il est ouvert dans la zone de l'ouverture pratiquée à l'extrémité du pot; il est doté d'une garniture d'étanchéité permettant d'étanchéifier l'intervalle (17) entre le boîtier intermédiaire et le pot et il est relié via une conduite d'alimentation (18) à un dispositif d'alimentation en gaz léger qui permet de maintenir une atmosphère de gaz léger dans l'intervalle.
