Abstract
The beat‐up process has a great influence on the structure and appearance of the handmade carpet. Since all weaving processes of the handmade carpet are performed by the weaver, the production speed may be increased and the performance of the weaver may be improved by designing a suitable beat‐up mechanism. In this article, a crank‐rocker type of four‐bar mechanism has been studied for the handmade carpet loom beat‐up mechanism. First, the functional requirements of the beat‐up mechanism were established according to the problem statement. Later, a four‐bar crank‐rocker‐type mechanism was generated and developed from a slider‐crank‐type mechanism. Here, the dimensional synthesis of the mechanism was made as a solution to the slider‐crank‐type mechanism. Many alternative mechanisms were generated as a result of the dimensional synthesis. The slider‐crank‐type mechanisms were then translated into the crank‐rocker‐type mechanisms. These mechanisms were evaluated in terms of some mechanical criteria and the most suitable one was selected. Finally, a kinematic analysis of the beat‐up mechanism was performed.
