Abstract: 430,742. Mouthpiece cigarettes. MOLINS, W. E., 2, Evelyn Street, Deptford, London. Sept. 21, 1933, No. 26098. [Class 130] A mouthpiece cigarette is made by first aligning a cigarette and a mouthpiece or stub, moving them axially, and then, while they are so. moving, securing a severed length of wrapping material, e.g. a cork tip, around the adjacent ends of the cigarette and stub to unite them. Alternatively, two cigarettes with a doublelength stub between them are united by a severed length of tipping material, the composite cigarette being then cut through the stub to form two cigarettes. Preferably, however, double-length cigarettes and stubs are employed alternately in a continuous stream, the composite rod so formed being cut through the stubs 33 and also between the ends of each cigarette as shown in Fig. 11. The cigarettes are fed one at a time from a hopper 14 to an endless tape 20 above which is disposed a rotating member 21 adapted to co-operate therewith and move the cigarettes so that spaces are left between successive cigarettes, and double-length stubs are fed by a conveyer 30 from a hopper 22 to the said spaces, the cigarettes and stubs being then conveyed by the tape 20 over a bridge piece 36 to a conveyer constituted by belts 34, 35. Mechanism comprising a rotating drum 37 with spring-urged fingers 39 is located at the bridge piece 36 for positively moving the cigarettes and stubs towards the conveyer 34, 35, the latter being driven at a slower speed than the tape 20 if it is desired to bring the cigarettes and stubs into contact before applying the tipping material. At this stage the tipping material from a supply spool 42 is applied to the cigarettes and stubs, the material being fed by driving rollers 44, 45 past a knife 46, which cuts it into tips 50, to a suction roller 48 over which the belt 35 is guided, and the tips being gummed by a roller 49, preferably as shown in Fig. 7 by the shaded lines, while they are on the said roller 48. The tips are then conveyed to the cigarettes and stubs by the belt 35, the latter being subjected to suction during this part of its travel. The cigarettes &c. are then transferred to an endless tape 54 above which is provided folders 55, 56 adapted successively to fold down the edges 51, 52 of the tip, after which the composite rod thus formed passes to a heater 58 and severing mechanism 59 located near a cigarette collecting band 60. A stub is defined as a filter plug, a mouth-piece which may be empty or filled entirely or partly with filtering or flavouring material or tobacco, a composite mouthpiece constituted in part by a length of wrapped tobacco rod and in part by a length of filtering or flavouring material or a tubular piece either hollow or entirely or partly filled with filtering or flavouring material, or a mouthpiece comprising a length of tobacco filler in a wrapper which tobacco is of a different kind from that in the cigarette. According to the Provisional Specification, a continuous length of wrapping material may be applied to the cigarettes and stubs so that a continuous rod is formed which is thereafter cut to the desired lengths.
