Abstract
Abstract A rotating shaving mechanism for the preparation of artichoke hearts including a circular knife mounted at an angle to the longitudinal extension of the artichoke. The knife is rotatable on an arm mounted on a rotatable shaft to enable the knife to be rotated about the central axis of the shaft while rotating about its own axis. The shaft is mounted in a support which may be displaced towards or away from the artichoke to be prepared.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A rotating shaping machine for shaving the bases of artichoke hearts, comprising support means, a rotatable shaft mounted in said support means, at least one arm member supported on said rotatable shaft, a rotatable knife means having a frustoconical wall diverging towards an artichoke to be prepared and having a circular cutting edge, said knife means being supported on said arm member so that the axis of said shaft is tangential to the cutting edge to impart an ovoidal shape to the bottoms of the artichoke hearts, means for rotating the knife means, means for keeping the artichoke co-axial with said shaft, and means for causing one of the knife means and the artichoke to be mutually displaced towards or away from one another.
Claim 2
Dependent Claim
124 words
