This invention relates to a groove rounder especially for a rye dough, which device comprises a treatment table (1) and a frame thereof as well as two treatment elements (3) moving in contact with an upper surface of the treatment table and arranged parallely in a longitudinal direction of the treatment table (1), for performing a groove-rounding operation, whereby each treatment element (3) is by means of two transverse arms (4) joined to its own pair of eccentrics (7; 8) rotating on vertical shafts (5; 6), of which one pair of eccentrics (7) is larger than the other pair of eccentrics (8), and which pairs of eccentrics (7, 8) are arranged to rotate at an equal and similarly oriented rotational speed, thus providing for both treatment elements (3) an operational movement, which follows a circular path and maintains the longitudinal position of the treatment elements (3). The groove rounder is characterized in that it contains an endless conveyor belt (2) moving in the longitudinal direction of the treatment table (1), on top of which belt the treatment elements (3) in the form of troughs, open against each other, move, whereby the pairs of eccentrics (7, 8) are arranged to rotate in such a direction that the treatment trough (3) driven by the larger pair of eccentrics (7) moves against the travelling direction of the conveyor belt (2) when being in the vicinity of the central line of the conveyor belt (2), and that the movements of the treatment troughs (3) are synchronized with each other such that both treatment troughs (3) at least momentarily move together towards each other and correspondingly away from each other. |
