The purpose of this paper is to compute and design the transmission crank mechanism of the rotary die machine. The authors chose a reasonable solution to design the experimental model to produce flower pots with dimensions of 1000 x 400 x 400 mm. The principle diagram and the dynamic diagram of the machine are presented. Computation and design of main clusters and hand fabrication of the rotary die machine are investigated. The model of the transmission crank mechanism is fabricated to verify the validity of the proposed modelen-USjournal-article
