Abstract: An apparatus for manufacturing wafers is disclosed that includes a pair of rolls each containing cavities that form the wafers. The cavities each have outer edge walls that extend from the bottom portion of the cavity at an obtuse angle and the two rolls are arranged so that the cavities become effectively mirror images of each other as they engage at the nip. The cavities also have portions rising from the bottom thereof that impress a design substantially equal from both sides to proclude warping of the bread.

Abstract: Wafers are produced by guiding a sheet of bread having friable outer crusts and a relatively soft center through wafer forming apparatus. The apparatus includes a pair of rolls, one of said rolls, i.e., a cutting roll having one or more wafer forming recesses or cavities therein and the other roll being a pressure roll which operates in rolling engagement with the cutting roll. As the sheet of bread is introduced into the nip formed between the two rolls the pressure roll acts to press the bread into the cavity or cavities on the cutting roll and into engagement with the edges of the cavity or cavities to cut wafers from the sheet of bread. Each cavity is configured to have a bottom surface which rises as a gradually tapering wall to a cutting edge which is coterminious with the surface of the cutting roll.

Abstract: An ornament plate supplied into a mold is punched out from a continuous sheet by a peripheral knife edge at an end of a press core member and advanced to a place which defines a part of a molding cavity. The press core member has a concave space in the end face thereof surrounded by the knife edge, the area of the concaved space being equal, in developed view, to the plane area of the punched ornament plate. The press core member has applied therethrough vacuum by which the punched ornament plate is attracted to the concave end face of the press core member during injection of molten thermoplastic resin.

Abstract: An apparatus for cutting out and simultaneously decoratively impressing a top crust for a filled pie from a rolled out sheet of dough having a flat annular sturdy plate with an upper side from the center of which a handle projects and with an underside from the circumference of which an annular cutting rim depends. Decorative die elements are removably provided on the underside of the plate within the area circumscribed by the cutting rim and form selected decorative depressions in the pie crust section as it is cut out from a rolled out sheet of dough with the depressions being later filled in with a food coloring filler after the cutout pie crust section is placed over the filling in a pie.

Abstract: A machine for removing uncured concrete from the top surface of a cast concrete slab to expose the aggregate therein to provide a decorative surface finish. The machine utilizes a pair of counter-rotating brushes to remove concrete which has been prevented from setting by use of a surface retarder, thereby exposing the aggregate to leave an attractive exposed aggregate finish. The counter-rotating brushes deposit the uncured concrete brushed from the surface of the slab onto a conveyor which carries the concrete waste to the edge of the slab for disposal.

Abstract: The processing of thermoplastic materials by working the thermoplastic materials into a hot flat sheet. The sheet material is first deformed or scored into a series of parallel strands that are interconnected by thin ribbons of the thermoplastic material thereby retaining integrity of the sheet material. The sheet material is then severed along the score line of the thin ribbons to form parallel strands which are cooled and guided to a fly cutter which cubes the strand material.

Abstract: The invention relates to an apparatus for the continuous forming of high density, seamless candies from a strand of confectionary material provided with a viscous filling. Candy blanks are first cut from an incoming soft strand and then pressed into candy pieces of the desired shape. The apparatus includes cooperative complementally formed pairs of separating teeth as well as pairs of members for shaping the candy and stamping chambers arranged in a rotating rotor.

Abstract: A mold for forming a hamburger patty comprising upper and lower mold members. The lower mold comprises a flat disc portion of a suitable material such as stainless steel, etc. At the center of the disc, a wooden dowel or post extends upwardly, the dowel or post being annular or any other desired configuration. A half round rib extends annularly around the central dowel or post and spaced therefrom. The top of the mold is annular with a depending wall portion which defines the perimeter of the patty. The upper member has a central hollow post of the same shape as the lower dowel or post but with an internal diameter equal to the outer diameter of the lower post. This permits the upper post to slide over the lower post. The upper member is also provided with a complementary half round rib spaced from the central post and adapted to seat over the lower rib when the mold parts are positioned together. A glob or portion of ground meat is placed on the bottom portion of the mold surrounding the central post.

Abstract: Improved method and apparatus for stripping insulation from the end of the electrical conductor of an insulated wire to expose a predetermined length of the conductor whereby the remaining insulation does not shrink when the wire is subjected to heat. Means, including an improved insulation stripping blade, are provided for compressing the remaining insulation immediately adjacent the exposed end of the conductor and simultaneously heating the remaining insulation immediately adjacent the exposed conductor to cause the adjacent remaining insulation to adhere to the conductor.

Abstract: In a process and a machine for moulding ceramic articles, the provision of a substantially moisture impervious foil between the mould surfaces and the clay blank and the disposal of the foil after its use as a waste by-product. A foil exhibiting predominant plasticity rather than elasticity is selected to secure effective operation of the invention. The clay blank is extruded in strand form at a rate of extrusion which is independent of the rate of feeding clay blanks intermittently into the mould and a temporary storage station provides buffer capacity between the extrusion and moulding steps. The machine has structure adapted to achieve this operation.

Abstract: A tube perforating device for forming outlet openings in a tube, such as a plastic tube, having discharge openings for passage of air, or the like, where it is desired to diminish the sound of the discharge to a minimum, and the method of accomplishing such opening formations by multiple perforations with perforating members spaced as desired and having ovoid heads to permit perforations of the walls of the tube and withdrawing the head of the perforating means through the perforations, drawing the peripheral margins of the opening outwardly, leaving the inside wall of the tube smooth, thus diminishing turbulance therein, and said device having an adjustment permitting a selective penetration of both walls of the tubing, transversely, with just the point of the penetrating means perforating the bottom wall, forcing said peripheral margin outwardly on the bottom perforation, and withdrawing the said head through the upper wall penetration, again moving the peripheral margin outwardly, providing pairs of openin

Abstract: A plate for a device for the manufacture of so-called potato sticks from dough like material, said plate being provided with apertures separated from one another by separating ribs. In order to prevent that the sticks manufactured by said plate will not adhere to one another said separating ribs being provided at at least two opposite sides with slots or recesses by means of which ridges are formed on the manufactured sticks, which prevent that the sticks adhere to one another with large surfaces.

Abstract: A packing case or box having a bottom, opposing lateral side walls, opposing longitudinal side walls and upper side walls, or fixed flaps, at opposing edges of the lateral side walls is produced from a blank piece of thermoplastic material, and an apparatus is provided for producing the packing case which is operated to perform the steps of melting and cutting unnecessary portions for forming the case by pressing a heated die upon the sheet of stock and at the same time impressing scorings or grooves upon the stock to be folded, folding the portions of the side walls and the fixed flaps defined by the scorings or grooves immediately after withdrawal of the heated die from the stock, and welding the heated and melted end walls of the connecting side portions of the stock in a folded position while the stock is in its molten state.
