Patent ID: 7182588

Claim:
Apparatus for continuous producing of a dough strip ( 6 ), the width thereof is a multiple of its thickness, from a dough mass ( 5 ), with at least one pair of oppositely disposed elongated guiding elements ( 8 , 9 ) for the dough, which guiding elements are formed by rollers ( 10 ) and are adjustably spaced apart from each other, wherein the dough passes through the gap ( 15 ) formed by this spacing, which gap ( 15 ) is delimited by the at least one pair of guidling elements, each guiding element having at least two rollers ( 10 ), so that the dough is guided by the rollers ( 10 ) driven in opposite direction of revolution from an intake end ( 16 ) of the apparatus to an outlet end ( 17 ) thereof, and wherein the width of the gap, when measured between oppositely disposed rollers ( 10 ), decreases from the intake end ( 16 ) towards the outlet end ( 17 ), and at least one of the rollers ( 10 ) is provided with a profile ( 19 ) on its periphery, which profile is formed by a plurality of grooves ( 20 ) extending side-by-side crosswise the longitudinal direction of the respective roller ( 10 ), which grooves enhance conveying the dough through the gap, characterized in that the rollers ( 10 ) of each roller set ( 8 , 9 ) have a circumferential speed that increases in correspondence to narrowing of the gap towards the outlet end ( 17 ) and that the at least one roller is provided with the profile ( 19 ), so that the grooves ( 20 ) constitute an evading possibility for bubbles present in the dough ( 5 ), however keep the bubbles within the dough.
