摘要

Machine readable identification marking on a roving tube (1) is provided by attaching a transponder (10) and using reading and writing equipment at the various processing stages. The transponder can provide a description or information on e.g. batch or machine number, machine position or production time. It can be in the form of a self-adhesive label at the top or bottom of the tube Alternative forms can be open spring clips or an integral construction with the tube so that it is fully covered by tube material. Writing devices can be installed at the roving frame or in the transport or transfer equipment. Reading equipment is positioned at the creel of the ring spinning machine.
