ABSTRACT
There are three different principles to perform shedding motion which are; cam mechanism, dobby controlled mechanism and jacquard controlled mechanism. A dobby mechanism consists of three main parts; drive mechanism, selection mechanism and mechanism for transferring motion to the frames. Rotary dobby mechanisms are being used in shedding process of high-speed weaving machines. In this paper, design and synthesis of a novel drive mechanism had been explained. The drive mechanism, which is used in this research, is an eight component lever-gear mechanism. The most important innovation is in the motion transmission mechanism on the main shaft of rotational dobby. It is known that main shaft in rotary dobby has dwell period in only one direction. The novel drive mechanism is designed to make equally timed, double stand-by positioned oscilational motion. After designing of the rotary dobby, the mechanisms are produced and montaged. It was confirmed that dobby run well and durably with all mechanism and shedding process is precisely carried out. The experimental values of dwell angles at the right and left dead-center positions are similar to theoretical values. Experimental results show that; if the drive mechanism and dobby is generated with advanced technology, it is possible to use it in dobby industry.
