Definitions

  • the present invention relates to the field of the textile industry, in particular rectilinear combing machines and more particularly has for object a brush holder device driving on a straight combing machine automatic compensation for the wear of said brush.
  • This driving brush is used at each phase of combing the fiber heads and, as a result, it wears out regularly and its wear must be compensated for by a periodic reconciliation with respect to the circular comb, to ensure efficient combing of the fiber heads.
  • This adjustment of the position of the driving brush relative to the comb circular, to compensate for wear is currently done manually according to a period defined by the user of the machine and which depends essentially the resistance to wear of the brush, the aggressiveness of teeth or needles of the circular comb and penetration depth brush bristles between the teeth or needles of the circular comb.
  • the brush wear compensation operation that is to say the adjustment of the position of the driving brush relative to the circular comb, requires stopping the machine, which causes a fall yield and therefore a drop in production.
  • the object of the present invention is to overcome these drawbacks by proposing a device for supporting a sinking brush on a combing machine straight to automatically compensate for the wear of said brush while avoiding machine downtime and loss of yield corresponding.

  • the toothed pinion 9, forming the rotational drive means provided at the end of the part threaded 8 opposite the brush body 7, is preferably mounted on said end by means of a non-return device such as, by example, a freewheel 12.
  • the means 1 for mounting the driving brush 2 are integral with the body brush 7 of said driving brush 2, each device 6 for holding and automatic movement of said brush body 7 relative to the comb circular 5 being fixed on one end of the brush body 7 and cooperating with a fixing means with integral adjustment of the corresponding support of the jaw 3 'of the clamp 3 for presenting the fiber heads 4 to the comb circular 5.
  • the fixing means with integral adjustment of the support for the jaw 3 ' can be in the form of a simple integral nut with said support of said jaw 3 'by welding or in the form of a threaded tab secured to the jaw support.
  • the driving means 10 of each device 6 of maintenance of the corresponding end of the brush 2 and displacement automatic thereof relative to the circular comb 5 is formed under shape of a piston which can move in a cylindrical housing 11 of the housing forming the mounting means 1, the stroke of this piston being limited by the length of the cylindrical housing 11 and / or by stops not represented.

  • the driving means 10 is moved in a direction from C to D following the double arrow in Figure 3, so that the driving means 10 meshes with the toothed pinion 9 which, by through the non-return device 12, causes the rotation of the part threaded 8 which, by cooperation with the corresponding thread of the end of the brush body 7, causes said displacement of the brush 2.
  • the piston forming the driving means 10 is moved by the action of a fluid pneumatic or hydraulic or by mechanical action or electric, its return to the initial position can be ensured by means identical or under load from a compression spring 13.
  • the devices 6 for holding and moving brush body 7 relative to the circular comb 5 are symmetrical about a plane passing through the axis of the toothed pinion 9 forming the means for driving in rotation the threaded part 8 and parallel to the plane formed by the jaw 3 'of the presentation clamp 3 fiber heads 4 with a circular comb 5.
  • the parts threaded 8 of the opposite devices 6 will have reverse pitch threads.
  • the device according to the invention can be provided with an indexing means 14, constituted by a ball 15 held under pressure between two teeth of the teeth of the toothed pinion 9.
  • an indexing means 14 constituted by a ball 15 held under pressure between two teeth of the teeth of the toothed pinion 9.
  • the driving means 10 is in the form of a sliding element meshing temporarily with the toothed pinion 9.
  • this driving means 10 can also be in the form of a second toothed pinion meshing with the toothed pinion 9 or a worm extending orthogonally to the toothed pinion 9, said second pinion or the worm being controlled in rotation by means of a stepping motor or a flexible or rigid drive shaft.
  • the toothed pinion 9 can be mounted entirely integral in rotation with the end of the threaded part 8.
