Abstract

685,761. Cigarette-making machines. MOLINS, D. W., RUAU, F. F., JACKSON, N. W., and MOLINS MACHINE CO., Ltd. May 18, 1950 [June 2, 1949; Sept. 22, 1949], Nos. 14835/49 and 24417/49. Class 130. In a machine making a continuous composite rod of tobacco filler lengths T and stubs S from an unwrapped tobacco stream interrupted at intervals by the feeding of the stubs thereto, tobacco in the leading end part of each separated filler length is positively engaged and accelerated so as to cause it to move forward faster than tobacco behind it in the length. Tobacco showered from a hopper (not shown) onto an endless moving band 2 passes through a guide tube 3 and into and through a flute of a fluted drum 4 which is intermittently rotated to cut sections from the tobacco stream and replace them by stubs S delivered into the drum flutes as from a vertical shoot 5, the composite rod thus formed passing through a further guide tube 6' onto a paper web 19 moving more slowly than the band 2 and which carries the rod beneath a tongue 7 to the usual gumming and folding devices (not shown) of a continuous rod cigarette-making machine, the wrapped rod being later divided into mouthpiece cigarettes by cutting it through the middle of the stubs and tobacco lengths. An arm 15 pivoted both on a rotary disc 14 and, by a link 17, to a fixed point 18, has finger portions 12, 13, which may be 16 mm. apart, moving in the paths indicated by chained lines so as to enter, through a slot in the tongue 7, the leading end of each length T as it passes under the tongue. The leading finger 12 enters the path of the tobacco about 5 mm. behind a stub, and thereafter moves faster than the web 19 so as to act in the manner of the invention and tend to cause both closer abutment between the relevant length T and the preceding stub S and the reduction of any inhomogeneity which may have been caused by compression of the leading end of the length T as during cutting. According to the first Provisional Specification, the finger 12 enters the path of the tobacco 3 mm, behind a stub, and, according to the second Provisional Specification, it enters about 8 mm. behind a stub. Specifications 430,742, 669,557 and 669,559 are referred to.
