Angled dough cutter

Claim 3

A method as in claim 1 in which the dough is first forced through a vertical inlet tube communicating with the discharge tube.

Claim 4

In a machine for extruding and cutting raised dough the improvement comprising (a) a substantially vertical dough inlet tube; (b) a dough discharge tube and end surface below the inlet tube, communicating therewith and angled therefrom; (c) the discharge tube end surface defining but a single through outlet opening; (d) the end surface defining the outlet opening being inclined from a horizontal surface and having a longest dimension along the incline; (e) a knife mounted for cutting movement across the opening along the longest dimension from top to bottom; (f) the opening defined by the discharge tube being larger at the point reached first by the knife and smaller at the point reached last; and (g) a horizontally disposed conveyor positioned to receive material extruded from the opening and cut by the knife so that dough extruded from the opening and cut off by the knife will define a substantially circular body when it falls onto the conveyor.

Claim 5

In a machine for extruding and cutting raised dough the improvement comprising (a) a substantially vertical dough inlet tube; (b) a dough discharge tube and end surface below the inlet tube, communicating therewith and angled therefrom; (c) the discharge tube end surface defining but a single through outlet opening; (d) the end surface defining the outlet opening being inclined from a horizontal surface and having a longest dimension along the incline; (e) a knife mounted for cutting movement across the opening along the longest dimension from top to bottom; (f) the opening defined by the discharge tube being larger at the point reached first by the knife and smaller at the point reached last; and (g) a horizontally disposed conveyor positioned to receive material extruded from the opening and cut by the knife so that dough extruded from the opening and cut off by the knife will define a substantially circular body when it falls onto the conveyor.

Claim 6

The machine of claim 3 in which the end surface is defined by a removable die.

Claim 7

The machine of claim 3 in which the knife moves along the end surface defining the opening.

Claim 8

The machine of claim 5 in which the discharge tube is angled at approximately 45° from the inlet tube.

Claim 9

A dough cutter as in claim 6 in which the shape of the outlet opening is defined by two eccentric circles whose centres are spaced apart one-fifth of the length of the opening in the direction of travel of the knife and in which the top circle has a diameter of 85% of that length and the bottom circle has a diameter of 75% of that length.

Claim 10

A dough cutter as in claim 6 in which the knife is activated by a sliding collar so that the collar must travel substantially twice as far to cause the knife to cross the top part of the outlet opening than to cross the bottom part of the outlet opening so that uniform movement of the sliding collar produces substantially faster movement of the knife in the bottom part of the outlet opening than in the top part so as to improve the cutting action of the knife.
