Transfer applying machine

Abstract: An improved machine for automatically applying transfers such as tax stamps to multiple packages contained in a carton is disclosed. The machine comprises a conveyor for advancing a carton through an opening station, where it is opened to expose the packages therein, through a stamping station, where tax stamps in the form of heat or water transfers or ink printing are applied to each of the packages by a movable platen, and through a closing station where the carton is closed and resealed. The machine is adjustable to accommodate a variety of carton and package sizes and to apply the transfers to a selected part of each package in the carton accurately, while using stock transfer sheets on which the transfers are mounted with a predetermined spacing that does not necessarily correspond to the spacing of packages within the carton. The various sizes are accommodated by means of an adjustable stop mechanism which interrupts the motion of each carton as it passes through the stamping station to thereby stop the carton at a selected location with respect to the transfer sheet and the stamp transfer platen. After the transfer has been applied, the stop mechanism is activated to allow the carton to continue its motion through the stamping station. The adjustable stop and the platen are shiftable laterally with respect to the stamping station to apply selected transfers from the transfer sheet to the packages in the carton, and the stop is adjustable with respect to the platen to apply the transfers to selected locations on the package.

Method for forming a heat exchanger core

Abstract: An improved method for forming a heat exchanger core from a single elongated sheet of metal which is stamped to define longitudinally spaced corrugated sections and then is pleat folded between the stamped sections to define first and second groups of alternating fluid passages for indirect heat transfer between two fluids. During stamping of each corrugated section, edges of such section are clamped in place to define precise exterior dimensions and the corrugations are formed by stretching the metal to conform with a die. The stamped corrugations are shaped with triangular end reinforcements to control the location of the bends as the sheet is folded into the final shape of the core. Edges of the sections defining each passage in the first group are sealed together to prevent the fluids from leaking around such edges. In a modified embodiment, reinforcement strips of metal are placed between adjacent sections to permit operation of the core at higher pressures without increasing the thickness of the metal sheet.

Conductive layer attachment for printed circuit card - uses set of slots and resilient pressure tool in stamping system

Abstract: A method of attaching conducting circuitry to cards uses a sticking and stamping technique together with patterns of suitably shaped slots in the cards. The method is suitable for automatic production of circuit boards, and is more rapid than existing printing and etching techniques. Basically, the card (1) has a number of shaped slots (3) cut in it, which define where the edges of the conductors are to be produced. The slots have one sharp and one rouned edge. A metallic layer (2) is then stuck to the card (1) over the slots, using an unspecified adhesive, and a rubber or plastics member then presses the layer into the slots, fracturing it along the sharp slot edge. This produces the conducting pattern required.
