Abstract: 5422. Wictorsohn, A. March 14. Cigarette-making machines.-Relates to a machine for making paper cylinders fitted with mouthpieces, which are subsequently filled with tobacco to form cigarettes. The wrapper cylinder is made and pasted by the usual arrangements, and is cut by shears to the proper length. The shears move forward in the cutting to make room for the succeeding cylinder &c. This movement also pushes the cut wrapper to a conveying-device, which places it in position for the introduction of the rolled mouthpiece. The paper for the mouthpiece is a strip of the width to correspond with the length of the mouthpiece, and is rolled upon a shaft. The paper is drawn off a reel by rollers, and the length fed forward can be regulated. Shears cut the strip the required length, and small oscillating blades cut fringes in one corner which, when the mouthpiece is rolled, project inwards and form a stop for the filling. An oscillating arm strikes the paper if it is not properly rolled, and ejects it from the rolling-apparatus. The rolled mouthpiece is received into a tube on to which the wrapper cylinder is passed, and both mouthpiece and cylinder are then removed, leaving the former in the latter. Fig. 8 shows in plan view the parts of the machine for forming the mouthpiece and inserting it in the wrapper cylinder. All the parts of the machine are driven from the main shaft 6, actuated by a hand-wheel or through belt gearing. This shaft operates the rolls for drawing in the wrapper paper through three crank rods forming a triangle. The wrapper cylinder shears are opened through a reciprocating frame &c. by a cam on the shaft 6, and are closed by a spring. The shears are arranged so that the lower blade pushes the cut cylinder forward on to the table 62, where it is received by reciprocating forks which move it into position for receiving the mouthpiece. The mouthpiece paper is fed into the machine through rollers 76, 77, &c., and pass under the stamping- apparatus 79, which cut the fringes, and from thence passes under a guide 80 to the feed-rollers 72. The lower roll is fitted with a segmental fluted piece which determines the length of the strip fed forward. The rollers 76 &c. are driven continuously, so that the strip forms a loop, thus preventing strain owing to the intermittent feed of the rollers 72. The shears 93 for cutting the strip consist of a fixed and a movable blade, the latter carrying a finger-piece which lifts the end of the paper after the cut. The end of the cut strip enters a slit in a tube carried by a hollow spindle 136, within which is mounted a toothed rod. The spindle and the rod are driven by a clutch operated by a rocking lever 147, tappets &c. being arranged so that the clutch first turns the rod, causing it to grip the strip, and then rotates the tube so as to wind the strip upon it. A slotted tube 164 on a travelling carriage is then passed over the formed mouthpiece, and is afterwards traversed to the left, so as to enter the wrapper cylinder. Catches 175 finally eject the mouthpiece and wrapper as before described. Should the mouthpiece not be properly gripped, a toothed blade 159 strikes the end projecting from the tube, drags it out, and ejects it through an opening in the bed of the machine. The completed tube is received by a cylinder 68, which rolls it into a perfect cylinder, and delivers it to a table 69.
