ABSTRACT:
A machine for the manufacture of twisted pastry bars comprises coplanar and spaced-apart supply and discharge belts, the supply belt being advanced intermittently to convey a strip of dough to a cutting station where the strip is cut into successive, transversely extending ribbons. Pairs of facing upper and lower conveyor belts are positioned between the supply and discharge belts, the conveyor belts defining therebetween a coplanar bed for conveying the successive ribbons to the discharge belt which supports and removes the twisted bars. While the ribbons are entrained by the facing conveyor belts, they are gripped at spaced positions against transverse displacement. Twisting devices are positioned in the clear longitudinal passage defined between the facing conveyor belts, each device comprising facing upper and lower belts in alignment with the passage and cooperating to grip the ribbons against transverse displacement, and being turnable about a transverse axis to twist portions of the ribbon adjacent to the gripped portions. Devices for flattening the twisted ribbon portions are arranged between the twisting devices and the discharge belt.
