Abstract
Abstract A stone fruit cutting apparatus for slicing apricots, this apparatus having a pair of substantially vertical belts defining a channel to guide and carry the fruit therealong to the cutting position. The cutter comprises a pair of vertical disc cutters displaced one above the other to give an upper and lower cutter, so that during cutting the fruit is supported by the belts and rotated to produce a cut around its circumference to the depth of the stone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
A stone fruit cutter including a pair of horizontally spaced substantially vertical belts, a stationary surface below said belt to define a channel open at the top and bottom to guide and carry the fruit therealong, a pair of vertical disc cutters displaced one above the other to provide an upper and lower cutter, so that during cutting the fruit is supported by the belts to convey the fruit between and pass said cutters and also rotate said fruit to produce a cut around its circumference to the depth of the stone, said fruit being fed into said channel by a chute which extends between and separates said belts at the inlet end to form said channel whereby fruit passing down said chute is fed into said channel.
Claim 2
Dependent Claim
