Definitions
- This invention relates essentially to a process for the direct winding, twisting or doubling of a thread, especially of artificial silk, in the shape of a conical bobbin with cross wound layers, the thread being wound on a cross wound bobbin, the speed of rotation of which varies.
- This variation of the speed of revolution is in each case adapted to the circumference of the cross wound bobbin. That is to say, when the larger circumference of the cross wound bobbin is being wound, then the bobbin revolves at a lesser speed, and vice versa, and consequently a practically uniform peripheral velocity and consequently a uniform thread tension results therefrom.
- the taking up speed of the bobbin be absolutely uniform at each moment of the winding, then of course it becomes necessary to carry out the winding opera-. ,tion in a particular manner; that is to say it must be effected in such a manner, that the conical winding surfaces of the bobbin shall always converge towards one and the ,same point-hereinafter called the apex of the cone.
- This particular type of winding is produced by the fact that less winding turns occur at the pointed end than the base or larger extremity ofthe bobbin, by reason of imparting an especial acceleration to the thread guide when feed-- ing thread at the smaller end of the cone.
- Anot "er object of the invention is to produce a novel and eflicient device for carrying out the process above mentioned.
- Fig. 1 is a front view of an arrangement with a driven bobbin spindle.
- Fig. 2 is a lateral elevation of a doubling or twisting device, using the winding device shown in Fig. 1.
- Fig. 3 is a front view ofan arrangement, wherein the conical bobbin is not positively driven, but is driven by means of a driving cone contacting therewith.
- Fig. 4 is a detail view of the bobbin holder seen from above.
- Fig. 5 is a side view of a doubling or twisting device making use of the winding device shown in Figs. 3 and 4.
- the twisting or doubling bobbin (n) shown in Fig. 2 is for instance arranged on a bobbinbframe; the bobbin (n) revolves at a high speed, and the thread (111.) is guided to the winding bobbin (a) over the head of the doubling bobbin through an eyelet of the thread guide and by means of a guide rod.
- This winding bobbin (a) is connected by means of a belt drive (b, c) with the shaft of the guiding cam (g) for the thread guiding rod (f') and with the thread guide (I) and is driven in conjunction with the guiding cam by meansof heart shaped gear wheels (d, e).
- gear wheels is such,- that the resulting speed of revolution corre sponds to the conicity of the winding bobbin, so that the product of the number of revolutions and the circumference of the bobbin, which is being wound at the time is in the main constant.
- the winding of the cross wound bobbin (a) is not desired to be effected 'in parallel layers, but in such a manner that the peripheral bobbin surfaces converge at all stages of the winding process on one and the same cone-apex, then the guiding cam for the thread guide (I) is shaped in such a manner that the inclination of the thread becomes less at the base end of the cone than at the small end thereof.
- the thread guide (1) is arranged to oscillate between a pair of collars on the rod 0) and that a rod (k) is fixed at (l) to lie parallel to the surface of the cone ((1) and engages the thread guide adjacent its free end to cause it to travel parallel to the cone or cop.
- the conical bobbin (a) is arranged to pivot around the point (I) ,on a holder 0:) and rests on a conical mandrel (i') the cone apex of which coincides with the pivotal centre (1) of the bobbin holder.
- the mandrel (i') is extended as a shaft or spindle (h') and is driven by means of gear wheels (b, c, o, p) and the cam shaped gear wheels (d, e).
- the guiding cam (g) is operatively connected with the gear wheel (d).
- the thread guiding rod (,f') with the individual thread guides (,f) is moved to and fro by means of the above mentioned guide cam.
- the guiding cam (9) may, as inthe device according to Figs.
- gear wheels ((1, e) are driven 1 and 2 be designed in such a manner that the thread guide movement is accelerated'when moving towards the smaller end of the bobbin (a) which acceleration is adapted to the decreased circumference in such a way that all winding surfaces converge towards one and the same cone apex, that is to say the point (I).
- the conical mandrel (i) is driven at a varying speed of rotation adapted in each case to the circumference on which the thread is being wound. This movement is transmitted to the conical bobbin (a) resting on the mandrel.
