Definitions
- the present invention relates to a traveller provided with a small roller for continuous ring spinning or ring twisting frames or for any other type of frame wherein twist is imparted to yarns with the aid of assemblies each of which comprises a ring and a traveller.
- the yarn frequently is subjected to a sudden deflection in its travel while at the same time being subjected to a certain degree of friction due to the tension exerted on the balloon of yarn upstream of the traveller, which said balloon causes the yarn to bear on the traveller.
- the traveller forming the subject of the present invention permits a substantial diminution in the degree of friction exerted on the yarn.
- the said traveller is characteristic essentially in that it is provided with a moving roller over which the yarn passes, in such manner as to diminish to the minimum the frictional effect of the yarn on the traveller, during spinning, or during double twistmg.
- the small roller may be associated with the body of the traveller in numerous ways, for example with the upper portion thereof, with its lower portion, or its median portion, externally or internally. It may be carried notably be a single or double angle member secured on the traveller in fixed manner with the aid of a screw, or moveably secured with the aid of a hinge or a ball device or in any other way.
- the angle member and the body of the traveller may also be cast in one piece.
- the roller may be mounted on its support pivot, directly through the agency of its hub or indirectly with the aid of ball or roller bearings.
- the roller is preferably of the type having flanges with a pronounced groove between the flanges, so as to ensure improved guiding.
- the use of a traveller provided with a small roller involves, however, the problem of orientation of the roller.
- the plane of symmetry of the roller should be identical with the plane formed by the two segments of the yarn immediately upstream and downstream of the roller, if it is desired to reduce the frictional effects on the yarn to the maximum extent.
- the angular direction of the yarn downstream is continually modified.
- the angular direction may be or may not be modified during windingon, depending on whether the yarn guide producing the yarn balloon point is fixed or whether it is subjected to displacement in sychronism with the ring rail.
- this modification is of small amplitude and it may, in practice, be assumed that the angular direction upstream is not modified, even in the case of a fixed yarn guide.
- the problem of the effect of the increase in the winding thickness may be solved by utilizing a roller secured on the traveller by means of a ball-joint system, this arrangement automatically imparting the desired orientation thereto, at any instant. It is also possible to utilise a roller carried by a pivot the angular direction of which is variable relatively to the traveller, in such manner that the plane of symmetry of the roler is able to orientate itself between two extreme positions corresponding to the commencement and termination of winding-on.
- the plane of symmetry of the roller constituting in fact the plane bisecting the plane angle formed on the one hand by a short segment of yarn upstream and on the other hand by the two segments of yarn downstream, on the one hand at the commencement and on the other hand at the termination of winding-on.
- the lateral flanges of the roller on either side of the groove should have an angle of inclination which is greater than or at least equal to that of the yarn travelling over the roller, relatively to the plane of symmetry of the roller.
- the radius of curvature of the groove connecting the two lateral inclined flanges will be greater than the radius of the yarn passing about the roller. 7
- the traveller according to the invention may be utilised notably for twisting and doubling heavy yarns offering a relatively high degree of resistance to flexing and/ or covered with a layer of an adhesion or bonding agent, which may readily be removed, with a consequent risk of fraying or unravelling, due to yarn friction.
- the traveller according to the invention is in particular suitable for the twisting of single threads or the cabling of glass filaments, intended for the reinforcement of pneumatic tires.
- these yarns and twisted filaments require first of all to be immersed in a solution of an adhering agent or bonding agent, so as to be thoroughly impregnated, and it is only after this treatment (with subsequent thermal treatment) that they may be subjected to twisting or cabling.
- FIGURES l and 2 show a traveller according to the invention, as seen from the front and from the side respectively;
- FIGURE 3 shows a traveller in the active position on its ring
- FIGURE 4 is a plane geometrical representation showing the orientation of the roller relative to the bobbin and to the winding.
- the traveller is C-shaped, having a body 1 and two curved arms 2 and 3 each of which has inclined outer faces 4 and 5.
- an angle member 12 Secured on the face 4 of the curved arm 2, by means of the screw 13, is an angle member 12.
- the angle member 12 carries, through intermediary of the screwthre-aded pivot and the nut 11, a small roller 6 having two flanges 7, 8 and a groove 9. The roller 6 is able to rotate freely on the pivot 10.
- FIGURE 3 shows the same traveller in the working position on the ring 14 shortly after the feeding of yarn to the bobbin 15. Due to the forces exerted on the yarn travelling over the traveller, the position of the latter is inclined and the face 4 is orientated in such manner that the plane of symmetry of the roller 6 constitutes the plane bisecting the plane angle formed on the one hand by a short segment of yarn upstream of the traveller and on the other hand by the two segments of yarn downstream, on the one hand at the commencement and on the other hand by the two segments of yarn downstream, on the one hand at the commencement and on the other hand at the completion of the winding-on.
- the arrangement of the bisecting plane is shown more clearly in the plane illustration of FIGURE 4.
- the plane of symmetry of the roller 6, with these two flanges 7 and 8, is represented by the bisector X-Y of the angle ARB, wherein R represents the roller, RA the tangent drawn from R to the stern of the bobbin 15, and RB the tangent drawn in a similar manner to the yarn winding 17, when the latter has attained its maximum diameter.
- angles BRY and ARY have a value of the order of 13
- the angle ORY, 0 representing the pivot of the bobbin
- the angle of inclination of the roller to the tangent to the ring at that point is of the order of 33.
- this orientation varies slightly from the commencement to the completion of winding, due to the variation in the traction angle on the roller and due to the play which must necessarily exist between the roller and the support ring, and it will, if necessary, be possible to make use of this variable to determine the position of the bisecting plane with greater accuracy.
- a ring traveller for a winding frame comprising a support member having arms disposed to slide around a ring and carrying means to guide a yarn from an external balloon onto a spindle, said guide means comprising a wheel having a peripheral groove formed by flanges adapted to receive and guide the yarn, means mounting said wheel on said support member for rotation about an axis lying in a plane substantially parallel to the plane of rotation of said traveller, said mounting means including a pivoted member adapted to permit swinging of said axis in said plane so as to accommodate the Wheel to the angle between the incoming and the outgoing yarn.
- a ring traveller as set forth in claim 1 in which the support member is C-shaped and the mounting means includes an upstanding bracket pivoted to said support member and carrying said wheel.
- a ring traveller as set forth in claim 1 in which said traveller rotates in a horizontal plane, said wheel is journalled for rotation about a horizontal axis, and said mounting is pivoted to provide for angular shifting of said axis in said plane.
- a ring traveller as set forth in claim 1 in which said support member is C-shaped and carries an upstanding bracket pivoted to swing about a vertical axis and said wheel is journalled for rotation about a horizontal axis on said bracket whereby the wheel is free to assume a position determined by the angle between the incoming and the outgoing yarn.
