1349244 Packaging cigarettes HAUNTWERKE KORBER & CO KG 19 April 1971 [29 Oct 1969] 41336/70 Divided out of 1349243 Heading B8C The description is identical with that with reference to Figs. 1-14 of Specification 1,349,243, but the claims are directed to a method for packing articles in which wrapper components and articles to be packed are conveyed cyclically and packing operations are performed during work cycles which consist in each case of a feed step and a stoppage phase and in which, after emission of a signal at any point in time to interrupt the packing operations, a work cycle which has already been commenced, is carried onward to the end of critical packing operations. The claims are also directed to a packing machine for carrying out the method. The description also includes a modification Figs. 15a-15d and 16a-16c of the machine according to Figs. 4a-4d of Specification 1,349,243. As shown, Figs. 15a-15d, tin foil blanks 2086 and paper blanks 2132 are supplied at points B<SP>1</SP>2 and B<SP>11</SP>2 to a finishing turret 2042 which forms part of a packing track Y2, prepared empty packets 2041 being transferred at a point B2 to a packing turret 2179. An additional gumming device 2291 is provided for gumming the open second bottom flap of an empty packet 2041 after the folding operation of the folder 2173 for folding one flap, and a supervisory control unit 2222 replaces the unit 222 of Figs. 4a- 4d. In operation, a wrapper feeder 2131 supplies and transfers a paper blank 2132 at the point B<SP>11</SP>2 where the blank is folded around a tin foil blank 2071 and bottom tucks are folded in by a folder 2127 as described for Figs. 4 and 13 these operations being controlled by the unit 2222 in dependence upon the supply of cigarette blocks 2008 to the feed path U2. The empty packet is completed as described for Figs. 4 and 13. At a transfer point B2, the finished packet is transferred by a transfer device 2175 into a holder 2178 of turret 2179 and at an assembly point C2 the block 2008 which initiated the feed of the blanks 2071 and 2132 is assembled into the packet 2041, by the means described with reference to Figs. 4 and 13. If the machine is stopped at any point in time which is critical for one or more of the packing operations, such as gumming, folding or transfer of blocks 2008 between turrets, the machine can only come to a standstill at the end of one work cycle at which all critical operations are completed. The additional gumming device 2291 ensures that gumming of one surface is completed during one cycle. The machine is controlled by electropneumatic circuitry which is described in detail with reference to Figs. 16a-16c (not shown). Specification 1,349,251 is referred to.
