ABSTRACT:
A dough-rounding apparatus in which first and second groups of elements undergo relative revolving movements to round pieces of dough. The elements of one group have chambers for receiving the pieces of dough, the elements of the other group being formed by circular recesses in a working surface which are opposite the chambers. The working surface has a limited region immediately adjacent to and surrounding each circular recess which is of broken, irregular formation to achieve a roughening of the working surface different from the circular recess. The limited region can be circular and concentric with the associated circular recess, the limited region having a diameter between 1.6 and 2.2 times the diameter of the circular recess.
