A rotary transfer apparatus, comprising a frame structure; a rotatable main shaft supported by the frame structure; a first planetary member connected to the main shaft; at least one first planetary shaft rotatably connected to the first planetary member and rotating in relation to the main shaft; a secondary body connected to each first planetary shaft; a second planetary shaft rotatably connected to each secondary body and rotating in relation to the first planetary shaft; an article transfer mechanism connected to each second planetary shaft; and an offset cam mechanism. The article transfer mechanism is adapted for picking and placing articles, and has at least one stem connected to the second planetary shaft. Each stem has a distal end whose motion defines a product path about the main shaft. The product path has at least two apexes, with one apex wherein the distal end of the stem moves in an in-line motion and another apex wherein the distal end of the stem moves in a non-identical motion. The offset cam mechanism is adapted for providing both in-line motion and non-identical motion at the apex(es) of the product path.
