Patent number: 4972669Abstract: An automatic sliver can replacement apparatus is combined with an automatic spinning machine for replacing empty sliver cans with full sliver cans. Sliver supporting carriages are guided to travel along the spinning machine with full sliver cans being supported at alternating can locations on the carriages and intermediate can supporting locations being unoccupied for supporting empty sliver cans. Another carriage movable along the spinning machine supports a can manipulating mechanism equipped with sensors to recognize and distinguish empty and full cans on the transport carriages, the manipulating mechanism being operable in association with the sensors to transfer empty cans from the spinning positions to the empty can locations on the carriages and to transfer full sliver cans from the carriages to the spinning positions of the spinning machine.Type: GrantFiled: August 30, 1989Date of Patent: November 27, 1990Assignee: W. Schlafhorst & Co.Inventor: Hans Raasch

Patent number: 4969323Abstract: A spinning machine is disclosed which includes a sliver feeding device for introducing sliver into a spinning unit from a sliver container. To accommodate picking out the starting portion of a new sliver from a container and for connecting it with an end portion of the old sliver entering the spinning unit, apparatus is provided for picking up the new sliver and supporting the same in such a manner that the old sliver and the new sliver overlap one another in the area of the sliver supporting device adjacent the inlet area of the feeding device of the spinning unit.Type: GrantFiled: January 27, 1989Date of Patent: November 13, 1990Assignee: Hans StahleckerInventor: Fritz Stahlecker

Patent number: 4964269Abstract: An apparatus for transporting spinning tubes along a textile spinning machine for use in supplying empty spinning tubes thereto and removing fully-wound spinning tubes therefrom, includes an endless flexible metal belt having a generally flat lateral extent, a plurality of spinning tube transport members mounted on the belt at spacings therealong, a belt guide arrangement for orienting the belt to travel in an operating path along the spinning machine with its generally flat lateral extent in upstanding facing relation to the spinning machine, and a drive for actuating traveling movement of the belt. Preferably, the apparatus is adapted for a textile spinning machine having spinning stations along each of two opposite sides thereof, the guiding arrangement serving to guide the belt in the aforesaid upstanding disposition along each side of the spinning machine.Type: GrantFiled: April 11, 1989Date of Patent: October 23, 1990Assignee: Zinser Textilmaschinen GmbHInventor: Friedrich h Dinkelmann

Patent number: 4956969Abstract: A method and apparatus for supplying sliver to the spinning stations of a spinning machine to wind a batch of a predetermined number of packages includes a sliver can transfer device, a sliver can conveying device, a sliver can filling device and a computer for controlling the operation of the various sliver can handling devices. Each spinning station is initially provided with a sliver can having a differing amount of sliver therein than the other sliver cans as the winding of the packages of the batch is commenced. The spinning stations are then continuously individually provided with fresh cans of sliver having a uniform amount of sliver therein during the normal running of the batch.Type: GrantFiled: September 7, 1989Date of Patent: September 18, 1990Assignee: W. Schlafhorst & Co.Inventor: Hans Raasch

Patent number: 4953348Abstract: A synchronous yarn feeding device comprises a yarn feeding drum and a driving belt. The drum is provided with protrusions or studs that are arranged for cooperative engagement with concave surfaces or holes in the driving belt. A portion of the driving belt presses yarn onto the drum such that rotation of the drum and feeding of the yarn are synchronous with the speed of the driving belt.Type: GrantFiled: October 23, 1989Date of Patent: September 4, 1990Inventor: Jen F.
