Abstract: A pie crust dough roll out and trimming mold assembly includes a flat base element having a roll out surface thereon and an array of apertures therein for accommodating various size ring mold elements and for preventing their slippage relative to the base by cooperating with protuberances extending from the bottom surfaces of the rings. The ring elements have narrow top surface areas for pinching off excess pie crust dough during the rolling out process, while having wide bottom surfaces for strength and stability. An inclined, downwardly sloping surface connects the narrow top surface area and the outside diameter of the ring elements. The ring elements include internal diameter walls that correspond in height to the desired thickness of the pie crust disc, the internal diameter of the rings corresponding to the external diameters of the desired pie crust discs.

Abstract: This invention consists of a combined rolling pin and dough cutter. It is made up mainly of a central shaft provided with a handle at each end, and a series of abutting cylindrical rollers, all of the same diameter, rotate freely upon the central shaft to function as a rolling pin. To perform as a dough cutter, a series of circular cutting discs are inserted between the rollers. These discs are of a larger diameter than the rollers, so that their cutting edge extends beyond said rollers. One handle of the shaft is permanently fixed to the shaft while the other handle unscrews from the shaft to allow the insertion of the rollers and discs. One of the handles of the shaft is bored with a longitudinal hole into which is inserted a center pin which is used for cutting circular sections of dough used in pie making.

Abstract: A machine to perform in one single operating cycle the molding and curing of tread rings for pneumatic tires, including a central drum rotating around its own axis and translatable about itself, surrounded by a stationary annular carrying structure, carrying radially a plurality of hydraulic or pneumatic double acting cylinders, each rod of the said cylinders being provided at its end turned towards the drum with a mold carrying platen to which there is fixedly secured the mold which is part of a complete annular form and which is part of a complete annular form and which may radially translate with synchronous movement, either going near or away from the surface of the said central drum.
