Blunt edge dough cutter
View Patent ↗A dough cutting apparatus is suitable for cutting a sheet of dough. The dough cutting apparatus includes a structure defining a blunt dough engaging portion. The present invention can be embodied in a number of different ways, including a wheel cutter, a rotary drum cutter, a reciprocating head cutter, or another cutter.
1. A dough cutting apparatus for shaping and cutting a dough sheet comprising:
a conveyor for moving a dough sheet in a dough travel direction, the dough sheet having an upper surface and a lower surface, said dough sheet being positioned on the conveyor with the lower surface of the dough sheet being in contact with and resting upon the conveyor, and the upper surface being defined by a skin of the dough sheet, with the skin being spaced from the conveyor based on a thickness of the dough sheet, wherein the lower surface defines a second skin of the dough sheet;
at least one upstream set of wheels mounted for rotation about a first axis which is transverse to the dough travel direction, each of the at least one upstream set of wheels being spaced above the conveyor by a distance less than the thickness of the dough sheet;
a downstream set of wheels mounted for rotation about a second axis which is transverse to the dough travel direction, wherein the downstream set of wheels are in contact with the conveyor, wherein the at least one upstream set of wheels is configured to depress or locally stretch, but not break, the skin of the dough sheet toward the conveyor, while the downstream set of wheels is configured to sever the dough sheet and wherein the downstream set of wheels is further configured to draw the upper surface to the lower surface so as to pinch the skin of the upper surface and second skin together in shaping the individual products;
a head mounted for reciprocating movement relative to the conveyor;
a cutter having a blunt dough engaging portion, said cutter being disposed on the head and configured to intermittently engage the dough sheet upon reciprocation of the head relative to the conveyor to both shape and cut the dough sheet; and
a controller configured to reciprocate the head to cause the cutter to intermittently engage the dough sheet in forming individual products from the dough sheet.
