Title: Improvements in apparatus for manufacturing newspaper wrappers and the like
IPC: B41F13/44
Filed: 1927-09-21
Abstract: 298,755. Clark, E. W., Garrett, F. A., and Tanner & Co., Ltd., R. T. Sept. 21, 1927. Envelopes and the like, making.-A machine, such as that described in Specification 2677/08, for making boxpleated wrappers comprises a rotary printing device adapted to print on the successive lengths of the paper strip which are subsequently severed to form wrappers whilst the strip is being fed through the machine. Paper from a roll 12 passes beneath a gummer 20, associated with a pleating device 18 supported by the framing 10 of the machine, and slitting knives 22 to a printing device comprising a printing roller 44 and a blanket roller 49. These rollers are mounted on spindles 42, 46 journaled at each side of the machine in blocks displaceable along vertical slideways 34, 36 by screw and nut mechanisms operated by vertical shafts 78 geared to a transverse shaft 92 adapted to be rotated by a handwheel on a shaft 100 connected to it by a chain 96. The arrangement allows the spindles to be drawn together or separated to accommodate rollers of different sizes, each roller being formed in identical halves adapted to be secured together on square portions of the spindles. The rollers carry intermeshing gear wheels 104, 106 having a pitch diameter equal to the diameter of the cylinders, the gear wheel 106 on the blanket roller 49 being driven by a gear 114 on a shaft 108 through an idler gear 116 mounted on a frame 118 pivoted about the shaft 108 and adapted to be secured in its operative position by a bolt 120. The speed of the printing roller is thus in inverse ratio to its diameter. The paper is fed forward by pairs of rollers 122, 124 and 138 interconnected by chain gearing, the rollers 124 being driven by the gear 106 on the blanket roller through an adjustable idler roller 130 which engages a gear 128 on the lower roller 124. This ensures that the peripheral speed of the feed rollers is the same as that of the blanket and printing rollers. Each half of the printing roller carries a complete impression to be printed and the shaft 28 of a rotary guillotine knife 24, which cuts the strips into lengths, is therefore driven from the printing rollers at twice the speed thereof. A cam on the shaft 28 operates the slitting knives 22. The inking rollers are driven by a second gear wheel on the printing roller 44 and are mounted in an adjustable frame 144 to adapt them to co-operate with different sizes of printing rollers and to be moved aside to give access thereto. Ink is supplied by a trough 158 and roller 156 mounted on a displaceable bar 160 to a transfer roller 162 mounted on a frame 164 adapted to be oscillated by a slotted link 172 adjustably connected to a link actuated by a cam on the shaft 108.
