In the present paper, about planar 9-link conveying machine which is not discussed with consideration of layer arrangements of moving links, conditions which determine the minimum number of layers required to construct the conveying machine are formulated. Based on the above results, link profiles avoided mutual interferences among moving links are determined with consideration of the relative location of links on the same layer during a cycle of motion. In order to discuss the influence of profiles and elastic deformations of links and the differences of layer arrangements of moving links upon the link displacements from the ideal planes of motion of links, the dynamic characteristics of the machine are investigated experimentally.
