Abstract
Abstract A process and apparatus for forming a cup-shaped skin for a skin-enveloped food, in which a dough strip of predetermined width and thickness and a suitable extensibility is extruded through a hole of a plate by an inverted frusto-conical or pyramidal die. The extruded dough envelope is received on a vertically displaceable lifting plate of a shaping cup, where stuffing and sealing of the dough envelope may then be performed. The extruding die and the hole of the plate are so dimensioned that the resulting dough envelope will have a thickness gradient which tapers from a thicker central base portion to a thinner peripheral upper portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A process for forming a cup-shaped skin for a skin-enveloped food, comprising the steps of: placing on a plate having a hole a flexible dough strip having a predetermined width and thickness and an appropriate extensibility, extruding the dough strip downwardly through said hole of said plate by means of a lower shaping part having an inverted conical or pyrimidal shaping surface for the cup-shaped skin, said shaping surface and said hole being so designed that the difference between the diameter of said hole and the maximum diameter of said shaping surface is less than said predetermined thickness, whereby a cup-shaped skin having a thickness gradient gradually thinning from its bottom to top due to a gap difference between the hole and the shaping part and due to the extensibility of the dough strip is formed, cutting apart the cup-shaped skin by juxtaposing an upper edge of the shaping part with the hole of the plate, and placing the cup-shaped skin thus cut apart onto a lift plate within a shaping cup.

A process for forming a cup-shaped skin for a skin-enveloped food, comprising the steps of: placing on a plate having a hole a flexible dough strip having a predetermined width and thickness and an appropriate extensibility, extruding the dough strip downwardly through said hole of said plate by means of a lower shaping part having an inverted conical or pyrimidal shaping surface for the cup-shaped skin, said shaping surface and said hole being so designed that the difference between the diameter of said hole and the maximum diameter of said shaping surface is less than said predetermined thickness, whereby a cup-shaped skin having a thickness gradient gradually thinning from its bottom to top due to a gap difference between the hole and the shaping part and due to the extensibility of the dough strip is formed, cutting apart the cup-shaped skin by juxtaposing an upper edge of the shaping part with the hole of the plate, and placing the cup-shaped skin thus cut apart onto a lift plate within a shaping cup.
Claim 3
Independent Claim
193 words
An apparatus of forming a cup-shaped skin for a skin-enveloped food, which comprises; a shaping cup, a lift plate supported on a base of the shaping cup so as to be vertically movable, and a plate arranged above the shaping cup for supporting a dough strip of predetermined thickness, said plate having a center portion sloping inwardly and downwardly which portion is provided with a hole slightly smaller than an inner diameter of the shaping cup, and a shaping device for the cup-shaped skin arranged above the strip-supporting plate, comprising an upper cutting edge having an outer diameter slightly smaller than an inner diameter of the hole and a lower shaping part in an inverted conical or pyramidal form having an outer diameter at its upper end slightly smaller than the outer diameter of the cutting edge, said shaping part being vertically movable and being adapted to fit into the shaping cup through the hole of the strip-supporting plate, said hole and said lower shaping part being so designed that the difference between the diameter of said hole and the maximum diameter of said lower shaping part is less than said predetermined thickness.
