Abstract
Abstract An easily cleaned toroid forming apparatus has an improved frame assembly with a first frame sub-assembly receiving a second frame sub-assembly to position the dough batch feeding, forming, guiding and cutoff means of the second sub-assembly to deliver dough parts to the toroid forming means of the first subassembly. Each of the sub-assemblies has supporting structure to which sub-structure is movably mounted for movement between a closed operable position and an open cleaning position to provide access to the individual parts of the feeding, forming, guiding, cutoff and toroid forming means. The apparatus has a circular knife on a forming roller for dividing a wide ribbon of dough into two narrow ribbons of dough conveyed by a removable divergent path double conveyor to double bank cut-off, transfer and toroid forming means.
