An apparatus for forming a strip of dough comprises a framework (2) and two sets (21, 22) of superimposed rollers (23) disposed adjacent to each other and driven for rotation around their horizontal axes. The rollers (23) of each set (21, 22) are bearingly supported on a roller carrier (24) movable relative to the framework (2). The dough passes from above to below through the gap (50) remaining between the two roller sets (21, 22) which gap narrows to below. All rollers (23) of each set (21, 22) are driven in the same direction, however, the lower rollers (23) of each set (21, 22) being driven faster than the upper rollers of the same set. The roller carriers (24) of the two roller sets (21, 22) can be moved by eccentric means (36, 45) against each other or away from each other. For this, at each roller carrier (24) an eccentric (36, 45) is bearingly supported which is driven for rotation against the direction of movement of the dough. Each roller carrier (24) is bearingly supported on a further eccentric (36, 45) or on a connecting rod (51) at a point that is located higher or lower than this eccentric (36, 45). This further eccentric (36, 45) or, respectively, this connecting rod (51) is bearingly supported for rotation or pivotal movement on the framework. Thereby, the dough is gently brought into the desired shape.

L'invention concerne un dispositif pour former une bande de pâte, qui comporte un châssis (2) et deux ensembles (21, 22), placés l'un à côté de l'autre, de rouleaux (23) superposés, entraînés en rotation autour de leur axe horizontal. Les rouleaux (23) de chaque ensemble (21, 22) sont montés rotatifs sur un support de rouleaux (24) pouvant se déplacer par rapport au châssis (2). La pâte passe, de haut en bas, par la fente (50) formée entre les deux ensembles (21, 22) de rouleaux, laquelle se rétrécit vers le bas. Tous les rouleaux (23) d'un ensemble (21, 22) sont entraînés dans le même sens, les rouleaux (23) inférieurs de chaque ensemble (21, 22) étant toutefois entraînés plus rapidement que les rouleaux supérieurs du même ensemble. Les supports de rouleaux (24) des deux ensembles (21, 22) de rouleaux peuvent être, par un excentrique (36, 45), amenés l'un vers l'autre ou éloignés l'un de l'autre. A cet effet, sur chaque support de rouleaux (24) est monté un excentrique qui est entraîné en rotation dans le sens opposé au sens de passage de la pâte. Chaque support de rouleaux (24) est monté en un emplacement plus haut ou plus bas que cet excentrique (36, 45), sur un autre excentrique (36, 45) ou sur une bielle (51). Cet autre excentrique (36, 45) ou cette bielle (51) est monté(e) sur le châssis de façon à pouvoir tourner ou pivoter. Grâce à ce dispositif, la pâte peut être mise dans la forme souhaitée avec ménagement.
