Abstract: 777,602. Making cartons. METAL BOX CO., Ltd. Oct. 28, 1955 [Nov. 2, 1954], No. 31728/54. Class 18. A tray-form carton held in the erect position by glued joints is set up by a plunger pressing a blank into a die, the plunger carrying elements moveable relative to it to press the glued carton portions against the die. The blank is fed beneath the plunger 13 by a conveyer 9, the long edge of its lid flap abutting a stop 10. Heater elements 11 are provided on both sides of the conveyer path to activate the adhesive, polyethylene for example, previously applied to the blank. The plunger 13 is mounted on a vertically reciprocating carrier 15 with provision for relative movement towards the carrier against the action of springs 18. Mounted within the die 1 is a plate 3 connected by rods 4 to a member 5 and biassed into the upper position shown in Fig. 4 by a spring 6. As the plunger and carrier descend, rods 19 on the carrier engage rear edges of the blank to ensure its correct location against the stop 10, and the plunger then forces the blank and' plate 3 to the base of the die with consequent folding up of the carton walls. When the plunger reaches the die bottom, the carrier continues its downward travel for a short period during which cam rods 29 carried by it press outwardly members 25 connected to plates 21 in the plunger sides. Parts 22 of the carton are thus forced against the die. As the carrier, plunger and plate 3 rise they carry the carton with them until it is stripped off by fixed members 31. An ejector 32, pivoted at 35 and operated by a roller 33 on the carrier and a cam surface 34, ejects the carton from above the die. The Provisional Specification states that the die may have tucker elements operated by cams movable with the plunger to fold in each corner tab during folding up of the carton sides. The pressure applying elements on the plunger may be operated by a fixed cam carried by the die. The whole of one side of the carton blank may be adhesive coated.

Abstract: 1,038,481. Etching; stencils. MORGANITE RESEARCH & DEVELOPMENT Ltd. July 22, 1964 [Aug. 15, 1963], No. 32328/63. Headings B6C and B6J. A thin metal sheet, which may be laminated, is formed by etching with a pattern of apertures which at one surface form a replica of a photographic image and at the other surface are slightly larger. An etching resist is applied photographically to one surface, which is then etched partly through the sheet to form cavities. The etched side is then protected by a resist coating, a resist is applied through a stencil to the other surface in a pattern of the larger apertures, and said other surface is etched through to meet the cavities. The resists are then removed to leave a sheet 14, Fig. 10. In another form, the first photographically applied resist acts as a plating resist and the surface is gold-plated. The plating resist is removed and the plate etched completely through, the gold acting as an etching resist, and the resulting apertures are tapered owing to undercoating, the finished sheet being thus gold-plated on one side, Fig. 19. If the metal is phosphor-bronze, the etchant is ferric chloride. The finished sheet is used as a vapour-deposition stencil for producing electronic circuits.
