Abstract
Sliver is delivered from a drawing frame to an open-end spinning frame in sliver containing cans and, at a transfer location along the travel path of a servicing device for the spinning frame, sliver is removed from the cans in partial lots and transferred to a sliver transport location on the service device to be transported to a spinning station whose sliver supply has been exhausted, whereat the servicing device performs the transfer of the sliver lot to the spinning station as well as the introduction end the piecing-up of the sliver.
Claims17
A method for supplying sliver taken from sliver containing cans produced at a sliver drawing frame to a plurality of aligned spinning stations of an open-end spinning frame which are serviced by a servicing device which travels in a path along the spinning stations to perform servicing operations thereat, the method comprising the steps of:
- transporting a sliver containing can to a transfer location at the open-end spinning frame located along the travel path of the servicing device,
- removing a partial lot of the sliver from the can at the transfer location,
- transferring the partial sliver lot to the servicing device,
- during subsequent servicing travel of the servicing device along its travel path, transferring the partial lot of sliver from the servicing device to a storage location at a spinning station whereat sliver is lacking and introducing the leading end of the partial lot of sliver by means of the servicing device into the spinning station, and
- then causing the servicing device to resume servicing travel along the spinning stations following the successful introduction of the sliver to the spinning station.
An open-end spinning frame comprising:
- a plurality of spinning stations for spinning sliver into yarn,
- a servicing device movably disposed to travel in a path along the spinning stations for performing servicing operations at the spinning stations,
- means on the servicing device for receiving and transporting a quantity of sliver,
- at least one sliver transfer location located along the travel path of the servicing device,
- a sliver transfer device for removing a partial lot of sliver from a sliver containing can at the transfer location and transferring the partial sliver lot to the sliver receiving and transporting means on the servicing device,
- a storage location at each spinning station for containing sliver being supplied to the spinning station during spinning of yarn, and
- means on the servicing device for transferring a partial lot of sliver from the sliver receiving and transporting means to the spinning station storage location of each spinning station.
