PROCEDIMENTO PER IL RIFORNIMENTO DI UN'UNITA' DI SERVIZIO CON TUBETTI DI BOBINA NUOVI, IN PARTICOLARE SU FILATOI A CAPI LIBERI, NONCHE'DISPOSITIVO PER L'ESECUZIONE DI QUESTO PROCEDIMENTO

Servicing units (3) are supplied with empty tubes (5), particularly in open e.g. doffing and donning tenders, end spinning machines by a conveying belt (1) passing parallel with the travel of the servicing unit. A tube (5) is positioned on the servicing @ by handling arms (6) in an intermediate position (II) between the point for further passing of the tube (5) for winding and the conveying belt (1) and, upon the signal for performing doffing, the tube (5) is passed from the intermediate position (II) for donning. Simultaneously the conveying belt (1) is brought into movement so that a further tube (5) is brought into contact with a positioning stop on the servicing unit, whence the positioned tube (5) is engaged by arms (6) and is transferred into the said intermediate position (II) whereupon the motion of the conveying belt (1) is stopped.
