Total Claims: 5
Claim 1
Independent Claim
144 words
Apparatus for manufacturing sealed sandwich style buns of the type embodying opposed slices of bread enclosing an inner filling, comprising: (a) a reciprocating cylinder; (b) a cutting device attached to said cylinder for cutting off crusts of sliced bread, further including: (i) a sharp blade in the form of a peripheral frame, and (ii) an inner shoulder extending inwardly of said blade so as to engage the periphery of a sandwich being cut; and (c) a rotatable table positioned beneath said cutting device, such that one-half of the table is disposed beneath said cutting device at any one time; said cutting device upon reciprocation against a sandwich supported upon said table being adapted to simultaneously cut off the crusts on the four sides of the sandwich, while said inner shoulder presses the peripheries of the sandwich to seal together the opposed slices of bread.
