Kynematics of Contemporary and Traditional Flyer Design

Abstract

Innovations in the fields of pneumatics, contactless sensors and programmable control of motors by high-power processors, have made possible a completely new approach in the design of flyers. A number of years of cooperation between textile engineers and electronics experts was necessary to develop electronic devices able to control the workings of a flyer. Through a thorough analysis of the working principles of mechanical controls for a flyer, textile engineers have obtained an algorithm of temporal functioning of the controlling device. Electronic engineers have translated the principles discovered into electronic circuitry which enables a technologist to control the machine through a computer. Contemporary flyers, with electronic controls, such as Toyota FL-100, is of extremely simple design, has no ratchet change wheel and no mechanical controls. Electronic control consists of a high-power processor which programmably controls the workings of the machine through two motors, and performs and controls precise roving winding on on biconical bobbins.
