Title (EN) METHOD FOR CONTROLLING THE WORKING CONDITIONS IN A PROCESSING MACHINE OF THE STAPLE FIBRE SPINNING PLANT AND APPARATUS FOR IMPLEMENTING THE METHOD
(FR) PROCEDE DE CONTROLE DES CONDITIONS DE TRAVAIL D"UNE MACHINE DE TRAITEMENT D"UNE INSTALLATION A FILER LA FIBRE DISCONTINUE, ET APPAREIL DE MISE EN OEUVRE DU PROCEDE
Abstract:
(EN) The working conditions between two rotating cylindres (4, 5), which are provided with a point clothing (9, 19) and are processing or mutually transferring a fibre web, of a processing machine of the staple fibre spinning plant are always maintained on a predetermined value by adapting the distance between the surfaces of the two cylindres (4, 5). For this purpose moving means (21) are used, which permit very precise setting of the distance between the rotational axes (8, 14) of the two cylindres (4, 5), and which are controlled by control means (22). To the control means (22) the measuring signal of a characteristic directly connected with the diameter of one of the cylindres (4 or 5), as scanned by a measuring element (25), is transmitted, and the control means (22) control the moving elements (21) in function of this characteristic. Thus complete elimination of the disturbing influences of the centrifugal force and of the increase in temperature of the cylindres onto the working conditions is achieved.
(FR) Les conditions de travail entre deux cylindres rotatifs (4, 5), pourvus d"un tissage a pointes (9, 19) et traitant ou transferant reciproquement un voile de fibres, d"une machine de traitement d"une installation a filer la fibre discontinue, sont toujours maintenues a une valeur predeterminee en adaptant la distance entre les surfaces des deux cylindres (4, 5). Dans ce but, des moyens mobiles (21) sont utilises, qui permettent un reglage tres precis de la distance entre les axes de rotation (8, 14) des deux cylindres (4, 5), commandes par des moyens de commande (22). Le signal de mesure d"une caracteristique en relation directe avec le diametre d"un des cylindres (4 ou 5), mesure par un element explorateur de balayage (25), est transmis aux moyens de commande (22) qui commandent les elements mobiles (21) en fonction de cette caracteristique. Ainsi, on elimine entierement les influences perturbatrices, dues a la force centrifuge et a l"augmentation de temperature des cylindres, qui s"exercent sur les conditions de travail.
