Definitions

  • ABSTRACT The device comprises at least one rotary ring against which the filament must be applied so as to be driven in rotation by the inner edge of the rotary ring to undergo twisting.
  • This rotary ring is driven by a single drive roller and the rotary ring comprises an outer edge of magnetic material. It is supported on said single drive roller by a fixed support roller and by a magnetic device inserted between the fixed support roller and the single drive roller.
  • the invention relates to twisting devices for filaments (that is to say for fine threads) especially for textile filaments. More particularly the invention relates to such devices comprising a rotary ring against which the filament must be applied so as to be driven in rotation by the inner edge of the rotary ring in order to undergo twisting.
  • the twisting device is characterised by the fact that the rotary ring comprises an outer edge of magnetic material, and by the fact that it is held supported on the single drive roller by a fixed support roller and by a magnetic device arranged between the fixed support roller and the single drive roller, this magnetic device being preferably arranged to draw said rotary'ring against the single drive roller and the fixed support roller.
  • the invention consists, apart from this main feature, of certain other features which are preferably used at the same time and which will be more explicitly considered below.
  • These rotary rings are staggered along a rectilinear path which the filament follows in the absence of the twisting device, that is to say a rectilinear path extending from the delivery device 2 to the fixing device 1.
  • These two groups A and B can undergo relative displacement, in a direction perpendicular to the rectilinear path, in order to pass from an inactive configuration for which the rotary rings 4a, 4b of the two groups A and B surround with play the rectilinear path of the filament 3 (FIGS. 1 and 3), to an active configuration, in which the rotary rings 4a, 4b of the two groups A and B come into contact with the filament 3 and oblige it to follow a sinuous path for which the filament 3 is applied against said rotary rings 4a, 4b so as to be rotated by their inner edge to undergo the desired twisting (FIGS. 2 and 4).
  • the two groups A and B are arranged so that when the two groups are in inactive configuration (FIGS. 1 and 3), the rings 4a, 4b of these two groups A and B are coaxial.
  • the single drive roller 5 comprises drive discs 8 cooperating respectively with the two rings 4a of the fixed group A and with the ring 4b of the movable group B.
  • This outer edge 53 and 54 can advantageously be constituted by a material such as that known under the trademark VULKOLLAN.”
  • the rotary ring 4a, 4b it comprises on the inside, one or several rings 55 with a rounded inner edge and constituted by a flexible or rigid material enabling the driving of the textile filament 3 (FIG. 5).
  • This or these rings 55 can advantageously be constituted by a material such as that known under the trademark VULKOLLAN.
  • Twisting device for textile filaments comprising at least one rotary ring against which the filament must be applied so as to be driven in rotation by the inner edge of the rotary ring to undergo twisting, said rotary ring being driven by a single drive roller, said rotary ring comprising an outer edge of magnetic material and being held supported on said single drive roller by a fixed support roller and by a magnetic device inserted between the fixed support roller and the single drive roller.
  • Twisting device for filaments comprising several rotary rings against which the filament must be applied so as to be rotated by the inner edge of said rotary rings to undergo twisting, these rotary rings being staggered along a rectilinear path and distributed into two overlapping groups so that in following said rectilinear path there is alternately encountered a ring of one group and a ring of the other group, these two groups being able to undergo relative displacement in a direction perpendicular or substantially perpendicular to said rectilinear path, this relative displacement being effected by pivoting around the axis of a single drive roller against which the rotary rings of the two groups are kept supported, each rotary ring comprising an outer edge of magnetic material, and being held supported on the single drive roller by a fixed support roller and by a magnetic device arranged between the fixed support roller and the single drive roller.
  • the rotary rings form a fixed group (A) and a movable group (B) and the single drive roller comprises drive discs cooperating respectively with the rotary rings which each comprise a groove formed in the outer edge and in which the corresponding drive disc becomes positioned, the one or more fixed support rollers and the one or more magnetic devices being carried by a fixed support when it relates to a rotary ring of the fixed group (A) and by a movable support when it relates to a rotary ring of the movable group (B).
  • each rotary ring comprises on the inside one or several rings with a rounded inside edge and constituted of a flexible or rigid material enabling the driving of the filament.
