Abstract
An open end spinning machine and an associated traveling sliver can replacement carriage are provided with cooperating components for automatically replacing empty sliver cans at the spinning positions of the machine with full sliver cans and threading up the sliver for spinning resumption. An openable and closable sliver guide is provided at each spinning position in association with a sliver monitor which recognizes the presence and absence of sliver in the guide. A signal transmitter at each spinning position produces a can replacement signal when the monitor recognizes the absence of sliver in the guide. A program controller is associated with a signal receiver on the carriage to actuate exchange of the empty sliver can at the signaling spinning position with a full sliver can from the carriage. The program controller also actuates opening of the sliver guide, insertion of the sliver from the replacement can thereinto, and splicing of the leading end of sliver from the replacement can with the trailing end of sliver from the can previously in service.
