Abstract

1401977 Linkwork BEASLEY FRENCH & CO Ltd 26 Sept 1972 [28 Sept 1971 8 Oct 1971] 45174/71 and 46969/71 Heading F2K [Also in Division B4] Apparatus for cutting or perforating a uniformly moving web of material, e.g. used in the manufacture of bags, at intervals along the length of the web comprises a rotatable shaft adapted to carry a perforating and cutting element extending axially of the shaft and radially outwardly directed for periodic contact with the web, and means for driving the shaft including a cyclic transmission 10-18, Fig. 1, the driving axis 12 and the axis 16 of the driven shaft being relatively displaceable so that the speed of perforating or cutting element can be matched with the speed of the web in the region of its contact with the web. The cyclic transmission shown in Fig. 1 comprises a so-called 4- baromechanism which includes a crank-arm 10 rotatable about an axis 12 of a driving shaft for the web feed drive and a second crank-arm 14 rotatable about an axis 16 of a driven shaft on which the perforating or cutting element is mounted, the cranks being coupled to each other by a link 18. The distance between the centres of the axes 12, 16 is adjustable, e.g. when both axes are in alignment the driving and driven shafts rotate at the same speed but when separated the driven shaft is rotated at a continuously varying rate throughout each revolution thereof. The axes 12, 16 are mounted in slideways which may be graduated in order to indicate the setting corresponding to a particular distance between successive cuts. The 4-bar cyclic transmission may be replaced by a slidercrank transmission, as shown in Fig. 5 in which an input shaft 42 is connected to a flywheel 44 having a slot 46 in which a block 48 is slidable. The block is pivotably connected to a sleeve 58 via a pin 52, the sleeve being coupled to an output shaft 62 which would rotate the cutter shaft. In order to balance the mechanism, a second block 50 is slidable in the slot and is connected to a counterbalance weight 68 having a shaft 64 rotatable within the sleeve.
