Abstract
A press for making pizza beds includes a mold plug having a plurality of pressure rings fitting telescopically and being guided within one another. Double-acting cylinders sequentially actuate the rings from the innermost one to the outermost one to act on the dough such as to stretch it from its center radially outwardly.
Claims2
A vertical press for making pizza beds comprising:
- a mold plug including a plurality of pressure rings being mounted to telescope inside one another in a guided fashion from a first position where bottom ends of said rings lie coplanar to each other and define a planar wall for said plug, to a second position where said rings are individually extended with respect to one another;
- means for driving said pressure rings individually in a vertical direction and
- a cloth of a non-sticking material which will not stick to the dough employed for pizza beds attached peripherally to an outermost pressure ring of said plug by spring-biased means and enclosing said plurality of pressure rings, wherein
- said means for driving the pressure rings individually comprise respective vertical axis, double-acting cylinders, each having a cylinder case attached to its respective pressure ring and a piston rod attached to a reaction wall of an outer adjacent pressure ring which guides sliding movement of an adjacent inner ring.
