Title: Machine for forming conical open ended tubes for paper or cardboard cups and similarcontainers
Filed: 1930-11-13
Abstract: 367,794. Machines for making paper tubes. ROSSER & RUSSELL, Ltd., Queens Wharf, Queen Street, Hammersmith, and WALLACE, J. L., 33, Bolinbroke Grove, Wandsworth Common, both in London. Nov. 13, 1930, No. 34224. [Class 99 (ii).] In a machine for forming paper &c. conical open-ended tubes, blanks of required shape are fed along a guide of corresponding form between a feeding and an adhesive applying roller, in such a way that. adhesive is applied to the blank only for the latter portion of its travel, after which the blank is rolled up to shape between an internal mandrel and a sleeve and is then immediately discharged from the mandrel while still wet and nested in the previously formed tube. The blank 25 is fed by hand along, a guideway towards an upper feed roller 7 to a lower pasting roller 9. The . latter revolves with a shaft 8, whose axis is fixed, while the shaft 6, actuating the feed rollers has within its length a Hooke's &c. coupling 58 to allow for vertical play. Parallel to the main driving shaft 2, which may be governed by a clutch 4 or fast and loose pulleys, is an auxiliary shaft 44 carrying double levers actuated by cams 45, 59 on shaft 2 the vertical motion of the end of the levers being utilized to raise the compound guideway 12, 13, pivoted at 24, and the shaft 6. - The blank is thus advanced by hand for the first portion of its motion out of contact with the gumming roller 9. The guideway 12, 13 and the shaft 6, are now lowered and the blank is pressed against the gumming roller 9. A wiper, with screw adjustment, is fitted within the gumming bath 10 to remove paste from the roller 9 along a surface corresponding with a central rail 17 which forms the main support for. the advancing blank. A mandrel 14, fixed to a shaft 26, is constantly rotated by gearing 29, 30 from the main shaft 2 and is moved axiallv with the shaft 26 by a cam 35 and bell-crank lever 32, 33 the mandrel being returned by a spring 36. Surrounding the mandrel is a split sleeve 37 which carries rollers 38 engaging the periphery of the mandrel through apertures and driven by frictional contact. The advancing blank is gripped between the rollers and the mandrel and is rolled to form a conical tube.. The half sleeve portions are now retracted by a cam 69, on shaft 2, and lever 68 operating through a wire 66 on the ends of spring-biased. spindles 61 carrying each portion of the sleeve. The mandrel, with the formed tube thereon, is now moved axially into a tube 40 carrying; resilient stripping fingers 41, 42, and on moving backwardly the formed tube 39 is left within the stripper where it nests within the tube previously stripped. The pasting roller is driven by gear 50, 60 and the shaft 6 by gear 49, 51 and sprockets 55, 57, operated from the main shaft 2. The stripping tube 40 may be heated to aid in drying the paste.

A method of forming a domed member from sheet or plate metal comprises fabricating from the metal a fluid-tight hollow body which has an annular side wall and two opposed end walls at least one of which has a curvature less than that required in the member, locating within the body during the fabrication means for preventing contraction of the side wall and inflating the body to increase the curvature of said one end wall to that required in the member. In an embodiment the curved edges 3, 4 of two slightly dished plates 1, 2 preformed from a plurality of steel panels 5 are welded to a circular cast iron die ring 6 provided with a peripheral groove 7 and radial apertures 8. Fluid pressure is supplied to the so-formed hollow body through an inlet 9 to inflate the plates to the required spheroidal shape after which the body is cut in two around the annular wall 10 to provide two similar domed members for use as the ends of a pressure vessel. The dish-shaped blanks may each be fabricated from a plurality of steel plates to provide a laminated structure. In another embodiment two discs 11 and 12 are welded around opposite edges of an annular side wall 13 of U-shaped cross-section the die ring 6 being disposed within the side wall (Fig. 5). The die ring may comprise two hollow tubes 6a separated by spacers 6b and strengthened by web plates 6c (Fig. 7). The inflated hollow body containing the latter type die ring may constitute a pressure vessel of spheroidal shape in which the tubes 6a are used for cooling fluid or fluid to be preheated. Alternatively, the tubes 6a of the die ring are replaced by mild steel rings separated by a spacer of lesser diameter to provide a peripheral groove. The rigidity of the domed end walls is increased by welding to the outer surface a series of circular plates 15 or a cruciform bulkhead to the inner surface of said walls. In a further embodiment the hollow body is wholly sealed and then expanded by the ignition of a slow-burning explosive, e.g. cordite, located therein.
