Title (EN) METHOD FOR OBTAINING BREAKINGS IN SEQUENCE DURING THE CHEMICAL FIBER SPINNING AND TWISTING AND IN THE SPINNING AND TWISTING MACHINES
(FR) PROCEDE POUR L"OBTENTION DE RUPTURES EN SEQUENCE DANS LE FILAGE ET RETORDAGE ET DANS LES MACHINES A FILER ET A RETORDRE
Abstract: front page image
(EN)This method makes it possible to obtain breakings in sequence of two fiber tapes (11", 12") exiting the drafting device one beside the other and not being twisted. Both tapes are fed towards a union point (13) and from this point they continue twisted together and in the form of a wire (14) toward a twisting bobbin (15) or similar so that the breaking of one tape causes the breaking of the other tape. According to the invention, in order to trigger the breakings with simple and safe construction means, this method is carried out so that the lateral displacement of the two-band assembly (11", 12") of fibers caused by the breaking of one of the two tapes fed to the bobbin or similar drives the assembly (14") into a slit (22, 23) which grips it and causes the breaking of the other tape of fibers (12", 11"). The invention also describes a spinning and twisting machine for implementing this method.
(FR)Le procede permet l"obtention de ruptures en sequence de deux bandes de fibres (11", 12") sortant du dispositif d"etirage a cote l"une de l"autre et non tordues. Les deux bandes sont alimentees vers un point d"union (13) et de ce point se dirigent tordues ensemble et sous forme d"un fil (14) vers un fuseau (15) de retordage ou analogue de la maniere que la rupture d"une des deux bandes a comme consequence la rupture de l"autre. Pour declencher les ruptures avec des moyens constructifs simples et surs, le procede d"apres l"invention est execute de maniere que le deplacement lateral de l"ensemble des deux bandes (11", 12") de fibres du a la rupture d"une des deux bandes alimentees vers le fuseau ou analogue entraine l"ensemble (14") dans une fente (22, 23) qui le serre et qui provoque la rupture de l"autre bande de fibres (12", 11"). L"invention comprend aussi une machine a filer et a retordre pour la mise en oeuvre du procede.
