Abstract

Bobbins spun in a ring spinning machine are conveyed sequentially to a measuring, counting and sorting device located between the ring spinning machine and an automatic winder that winds yarn from the bobbins. The measuring, counting and sorting device senses the presence of a bobbin, counts the bobbins being sensed, senses yarn and bobbin characteristics and compares the characteristics with predetermined standards. The device separates bobbins whose characteristics differ from the standard. Data regarding the operation of the spinning machine and operation of the winding machine are combined with the data obtained by the measuring, counting and sorting device and statistically evaluated for display or for controlling the production of the spinning machine and winding machine or for controlling conveyance of the packages from the winding machine.
