Synthesis of a new dobby mechanism

Abstract

In this paper the newly designed dobby construction is introduced. Dobby mechanisms are used to control elevation of frames which designate directly the warp motion and indirectly the structure of fabric on some types of weaving machines. The proposed mechanism is an electronically controlled, sixteen harnesses, middle closed, and positive dobby construction. Experimental working speed of the proposed mechanism has been reached up to 604 rpm, with convenient manufacturing cost and acceptable level of working noise. Main innovative value of the proposed dobby is absence of any reciprocating knife-hook pair in the mechanism.
