A dough rounding machine with a drum rotatable about a vertical axis, a frame disposed around the drum and a trough which is formed between the drum jacket and a number of trough elements mounted on the frame and extending helically adjacent the jacket. Each trough element has a rail fixedly mounted in the frame and abutting the drum, and a wall portion positioned on the rail and displaceable relative to the jacket. The dough rounding machine further comprises a control unit for adjusting the width of the trough, the unit comprising rotatable rods extending from the lower part to the upper part of the drum and substantially parallel to the drum jacket, and link means interconnecting the rods and the wall portions.
