Patent number: 4137701Abstract: The doffing of full bobbins built on spools placed on the vertical spindles of fly-frames equipped with revolving flyers is performed by combining gripping means such as resilient clips carried by each flyer with retaining means such as an annular groove formed at the upper end of each spool. The releasable axial coupling thus provided is capable of temporarily supporting a spool and full bobbin in the top position while the spindle is moved downwards in order to remove the spool.Type: GrantFiled: November 23, 1977Date of Patent: February 6, 1979Assignee: N. Schlumberger & CieInventor: Jean F. Herubel

Patent number: 4054250Abstract: In a textile winding machine each of a pair of arms is connected at one end to a first wheel and supports a bobbin at the other end in a winding position with the bobbin resting against a driving roller. An endless band, such as a chain, extends around and engages both the first wheel and a second wheel and also passes around a tension roller. The second wheel is connected to a motor for being selectively driven in each of two directions and for driving the first wheel via the endless band. When not driving the second wheel, the motor blocks rotation of the wheels. The tension roller is positioned by the action of tension control means which has an active and an inactive position. The tension control means includes a shoe abutting against a bladder adapted to be connected selectively to a source of compressed air and to a discharge.Type: GrantFiled: March 22, 1976Date of Patent: October 18, 1977Assignee: N.
