[Class 94 (i).] Cigarettes which have been made by severing a rod as shown in Fig. 1 at points 5 have the longitudinal seam oppositely arranged in consecutive cigarettes 6, 7, as shown in Fig. 2. In order that turning mechanism, dependent for its action upon the engagement of a finger with the seam of a cigarette, may operate with certainty, the cigarettes are separated into groups each containing only those with the seam arranged in one direction, and are fed back on to a common conveyer from both sides. In the form shown in Fig. 5, conveyers 8, 9 feed the cigarettes towards a central conveyer 10, past oppositely disposed engaging fingers 11, 12 for turning over incorrectly placed cigarettes so that all the cigarettes lie with their imprints upwards. The cigarettes next pass devices for causing them to assume an overlapping formation before being forwarded to the packeting apparatus by the central conveyer 10. The device associated with the conveyer 8, Figs. 5 and 6, comprises carriers 13 on the conveyer which feed the cigarettes over a rail 14 and beneath an adjustable guid 17 on to a bar 15 having a roughened surface 16, at which point the carriers disengage them and pass beneath the bar 15, while carriers 23 on a chain 23a engage them for further travel. A jointed lever 20, 22 pivoted at 29, bears on the top edges of the cigarettes, which pass on to the conveyer 10 in lapped formation as shown. The cigarettes arriving from the other side are fed on to a sloping path 31 beneath an inclined surface 30 on the underside of a coverplate 28 and are forwarded in appropriate groups by carriers 32 on to the common conveyer band 10 for feeding to the packing device. In another form of device for causing the cigarettes to assume an overlapping formation, illustrated in Fig. 8 (not shown), the cigarettes are first fed beneath springs, the raised rear wall of the conveyer chain members depressing the rear edges of the cigarettes. Further springs, pawls, or brush-like devices are disposed so as to engage and raise the front edges of the cigarettes during their further travel.

Title: Improvements in or relating to the erection of cartons or boxes
IPC: B31B3/44
Filed: 1962-09-03
Abstract: 1,017,056. Making cartons. MOTIVATIONAL PACKAGING Ltd., and P. H. P. HEAD. Dec. 3, 1963 [Sept. 3, 1962], No. 8310/62. Heading B5D. A carton blank is removed from a magazine 10 by a former 1 and retained thereon by suction means during subsequent erection of the carton about the former. In one embodiment a carton with gussets D folded against side walls B is formed initially and walls C are folded by a pair of spaced fingers 15 and are held down by cheeks 16 whilst a spring-loaded pivoted roller 17 first breaks the crease of the front side wall B and then of the rear side wall B. The side walls are pressed on to the former 1 by rollers 21, 22 resiliently mounted on arms 23, 24 rotating at four times the speed of the turret 2 about axes 25, 26, since there are four formers on the turret. The carton is finally " flicked " off the former 1 and dropped on to a conveyer 32. To produce a carton with gussets D folded against end walls C, the fingers 15 and cheeks 16 are removed to permit the sides B to be folded first; cheeks or fingers 29, 30 then hold the gussets along the ends of the former and the end walls are folded down between cheeks 31 before finally " flicking " the carton on to the conveyer 32. Instead of fingers 29, 30 rollers 21, 22 may have a thick surface layer of soft rubber which bulges around the edge of the former 1 when pressed thereagainst and thus folds the end walls C. For cartons with gussets formed on the outside, fingers 15 are retained but cheeks 16 are deleted and rollers 21, 22 are fitted with cheeks or fingers 29, 30. If heat-sensitive adhesive is used dielectric heating means are incorporated in the cheeks 31, the former being turned through 90 degrees if the gussets D lie against the side walls B. The turret 2 may be rotated about a horizontal axis (as shown) or a vertical axis. The former 1 is carried on an arm 3 with cam followers 6, 7 and a telescopic rod 8. On movement of follower 6 up cam face 11 the former extends radially into the magazine 10 to pick up a blank and then returns to rotate with the turret 2. At the end of the cycle movement of follower 7 along cam face 27 causes the former to " flick" outwards to eject the erected carton.

IPC: D04B15/38
Filed: 1956-03-16
Abstract: 814,005. Knitting-machines. F.N.F. MACHINERY MANUFACTURING CO. Ltd. March 8, 1957 [March 16, 1956], No. 8342/56. Class 74 (2). Each warp of yarns passing from its beam to the needles of a warp machine passes over a tension bar 3 supported by spring cantilevers 7. The cantilevers 7 are secured to a shaft 8 which has secured to it a bell-crank lever 13, one arm of which is formed as a toothed quadrant 15 for engagement with a pinion 16. The other arm of the lever 13 is attached to a rod 18a which slides through a fixed support 20 and carries a coil-spring 19a between the support 20 and adjusting nut 21. The resilience of the spring 19a is weak compared with that of the cantilever 7. The pinion 16 is secured to a shaft 17 carrying a flywheel 18 having a blade 27 adapted to operate micro-switches 30, 31. During knitting the cyclical variation in the tension of the warp is accommodated by the deflection of the cantilevers 7 whereas a permanent increase or decrease in the tension is sustained sufficiently to enable the flywheel to be rotated, whereby its blade 27 operates one of the switches 30, 31. These switches are in the circuit of a motor controlling a variable-speed gearing coupled to the warp beam and when operated cause an increase or decrease in the speed of the beam. Specification 718,097 is referred to.
