Abstract
Abstract A spinning frame having a plurality of spindles with bobbins thereon being wound simultaneously with yarn has a travelling service tender that monitors each spindle work station over a trip through all spindle positions to determine and correct malfunctions performed by an automatic service cycle performed at each spindle location work station requiring attention. Thus, full bobbins are detected and doffed, roll wraps are detected and stations disabled, flag down spindles are bypassed, and improper yarn feed is sensed and corrected by the service tender for each station encountered on a trip requiring such service. Stored data is retained to indicate the position and type of malfunctions and various indications of the machine performance and efficiency. Counters store data individually for each spindle and accumulate data for all spindles traversed. Provision is made to control the machine operation from either the detected or stored data by modifying the service cycles, the service trips, or shutting down operations if the danger of machine damage occurs. Alarms or other controls are operated from the stored data if the machine efficiency indicates the need for service outside the automatic tender operation, and the data is retained for indication of machine performance, efficiency and for trouble shooting analysis.
