Although the kinematic synthesis of planar function, point-path and motion gen-erators are vastly studied in the literature, surprisingly synthesis of line-path gen-erators is not formulized in detail. This study presents the formulization of the planar 4-bar line-path generator synthesis problem for up to 5 homologous posi-tions. Numerical examples for 3 and 4 line positions are presented for the illustra-tion of the formulations.
