DESIGN AND MANUFACTURING OF PNEU-MECHANIC DOBBY MACHINERY

Abstract

The contents of the shed opening frames used in the weaving machines and the pneumatic connections used in the dobby mechanisms of the shedding cost were made. As a result of the weaving, a new dobby with low cost, easy to manufacture and maintain was designed and produced in weaving machines. In particular, you can run a system that can manufacture fabrics with minimized tensions in warp threads. After executing the cam and tracking design, the drive, select, and motion acquisition to the frames were fabricated and assembled. After seeing the precise adjustments of the mechanisms, they were automatically operated at different speeds. Optimum results have been achieved in the incoming tension values in the warp with the new generation pneu-mechanical dobby machine, which is one of the shedding devices used to create sheds in Bizim Study weaving machines and provides the movements of frames for this purpose. The average warp tension during the weaving process was 34.6 cN.
