Definitions

  • the invention relates to a winding device with two spindle carriers arranged next to one another, on each of which at least one cantilevered, rotatably mounted winding spindle for receiving a winding tube for simultaneously winding threads into bobbins is arranged according to the preamble of claim 1.

  • a contact surface for a tube end of the winding tube is provided at the bearing end of the winding spindles, which is arranged in two adjacent stop planes.
  • a distance is formed between the stop planes, so that the winding tubes can be held in different axial positions relative to the winding spindles. It is irrelevant whether the winding device has only one winding unit or several winding units on each of the winding spindles. If several winding units are formed, the winding tubes are placed one after the other on the winding spindles as a tube spool, so that the respective bearing surface at the bearing end of the winding spindle determines the relative positions of the sleeves on the winding spindles.

  • Pressure rollers of this type are used at the same time for regulating the spindle drives, the preferred development of the winding device according to the invention, in which the pressure rollers are connected to one another by means of a gear mechanism in such a way that both pressure rollers rotate in opposite directions at the same speed, enables a regulation in which the rotational speed only one of the pressure rollers is sensed.

Abstract

La présente invention concerne un dispositif de bobinage comprenant deux supports d'enroulement (10.1, 10.2) horizontalement adjacents. Contre chaque support d'enroulement se trouve au moins un axe de bobine (7.1, 7.2) monté rotatif en faisant saillie, destiné à recevoir un cylindre de bobine (8) qui permet le bobinage simultané de fils (1.1, 1.2) sur des bobines (9). Les axes de bobine sont entraînés en sens inverse par des entraînements d'axe (23, 37) correspondants, un système de guidage de fils commun (2.1, 2.2) étant disposé entre les axes de bobine. Pour permettre, malgré un sens de rotation opposé des axes de bobines, l'obtention de bobines ayant la même structure d'enroulement avec un système de guidage de fils identique, les axes de bobine présentent à leur extrémité d'appui, respectivement une surface d'appui (17.1, 17.2) destinée à un extrémité des cylindres de bobine, lesdites surfaces d'appui étant disposées dans des plans d'arrêt voisins qui forment entre eux un espace (A). On obtient ainsi une structure à symétrie par rapport à un miroir, des bobines sur les deux axes de bobines, malgré une disposition asymétrique des bobines sur les cylindres de bobine.
