Definitions

the subject of this invention is improvements to creels for spinning machines; to be more specific, the subject of this invention is means known in themselves which are used in other machines with other functions, being installed on. creels for spinning machines.
One purpose of this invention is to be able to use very heavy supply bobbins having even small threads forming on . them, with the assurance that the bobbin will be pulled in rotation without false drafts of the roving.
a further purpose of this invention is to enable the roving to be pre-positioned as wished in automatic creels . wherein the bobbin is automatically replaced when it is finished.
this spiral is installed in spinning machines immediately upstream from the pulling rollers and serves to give the roving a greater consistency; that is to say, it serves to cause the roving to assume a false twist which induces a greater consistency in the roving itself.
the invention envisages a spiral twisting means positioned upstream from the first pulling rollers of. the drafting system, whereby the spiral twisting means acts as a guide for the roving being fed so as to provide consistency in the roving before the latter enters the drafting system.
the spiral twisting means being connected . to the automatic creel, serves to position the roving and . predispose it automatically for delivery to the drafting system since the gripping of the roving is made possible automatically owing to the false twist imparted to it.
the roving as it leaves the bobbins has a very low consistency; and it is known that during the phase of the unwinding of the bobbin itself it is possible for the roving to be sheared or to lose fibres, thus interrupting the regular work flow.
the spiral serves precisely to prevent this drawback.
the invention can be applied to normal spinning machines or to spinning machines with an automatic creel and with pre-positioning of the roving.
the invention therefore, is shown to consist in improvements to creels for spinning machines, whether such creels are stationary or automatic, the improvements being characterized by the fact that a spiral twisting means, known in itself, is installed immediately upstream from the drafting system and acts in such a way that it imparts to the roving. a false twist, which in its turn induces in the roving itself a greater consistency.
the invention is also concerned with spinning machines, whether they have a stationary or an automatic creel, characterized by envisaging upstream from the drafting system at least one spiral twisting means that serves to impart a false twist to the roving.
the bobbins 10 may be of a type with one or two rovings and may be positioned on a stationary creel or on an automatic creel with or without a mo - vable trolley to carry bobbins 19.
the roving, or rovings, II unwinding from the bobbin 10 owing to the action carried out by the drafting system 14-15 passes or can pass through a device 18 that checks the roving before the latter reaches the pulling roller 14 of the drafting system 14-15..
the roving II Before reaching the pulling roller I4 of the drafting . system, the roving II enters a spiral twisting means 13, which provides the roving II with a false twist that gives . said roving II a greater consistency precisely in the zone . where it is most likely to break.
the thread 17 is wound onto bobbins 16.
the spiral twisting means 13 can also be installed on a movable trolley carrying bobbins or on an automatic creel 19; in such a case the twisting means 13, besides providing the. roving II with greater consistency during processing, can . also serve as a pre-positioning element so as to facilitate. the gripping and delivery of the roving II to the organs 14. which pull or grip the roving itself II so as to send it on. the drafting system 14-15.
