A buckle folding machine comprises a stationary machine frame (1) and four parallel working cylinders (3, 4, 5, 6) which have the same outside diameter and in pairs define at least two folding nips for the material to be folded and are adapted to be rotated at the same speed by a common transmission. It is proposed that the four working cylinders (3, 4, 5, 6) and the common transmission are arranged in the rotary frame (2), which is rotatably mounted in the machine frame (1) and is adapted to be rotated by a drive in order to draw in, fold and eject the material which is to be or has been folded. At least one of the working cylinders (3, 4, 5, 6) which revolve with the rotary frame is displaceable in said rotary frame. At least one of the working cylinders (3, 4, 5, 6) is adapted to be positively displaced within the rotary frame (2) by a mechanical control device. Means for drawing in the material to be folded are povided, which is associated with the first folding nip and cooperate with the rotary frame (2) during the drawing-in and folding operations.
