<p>A device (10) for crimping and cutting dough ropes into a pillow-shaped longitudinal lengths is disclosed including a cutting roller (12) and an anvil roller (14). The peripheries (22, 24) of the rollers (12, 14) include a plurality of axially extending, spaced, parallel, linearly straight lands (26, 30) separating, forming, and defining a plurality of grooves (28, 32) therebetween. Compressible tubes (46) are stretched between end plates (36) located on the opposite axial ends of the cutter roller (12) and positioned in each of the grooves (32) thereof. The tubes (46) are compressed in the grooves (32) by the dough ropes as they are being crimped and cut by the abutment of the lands (26, 30) of the rollers (12, 14) together and expand and force the pillow-shaped longitudinal lengths of dough from the grooves (32) when the lands (26, 30) of the rollers (12, 14) separate. In the preferred form, the lands (26, 30) and the grooves (28, 32) of the rollers (12, 14) are offset from the axes (16, 18) of the rollers (12, 14) at a small angle in the order of 3° such that at least a portion of one of the lands (30) of the cutter roller (12) engages with a portion of one of the lands (26) of the anvil roller (14) during all times of rotation of the rollers (12, 14).</p> |
