Abstract: In the shell of an incrementally rotatable drum (8) for producing equal-sized round portions of dough a train of portioning chambers (5) is accommodated arranged parallel to the drum centerline and continually variable in volume for filling from a main chamber (3) by means of a main piston with a dispensed nugget of dough. Arranged in the region of the bottommost inflection of the drum (8) is a molding device (10) executing an eccentric circulating movement from without so that the nuggets of dough introduced into the train of portioning chambers (5) are roundly molded into nearly spherical portions of dough (11) and centrally positioned in the portioning chamber. Preferably the molding movement is implemented as an eccentric circular movement in which, starting from a zero position, a maximum possible molding excursion is made before returning to the zero position.
