    A machine for making oval cigarettes has a channel, through which tobacco is showered towards a suction conveyor, formed by walls which diverge in cross-section along at least part of the tobacco-receiving section of the conveyor so as to form a filler stream which is denser at the middle than it is at the sides, the angle of divergence being preferably at least 15<o> e.g. 19<o>. In the garniture area (22) of the machine, the cigarette filler stream is initially shaped without being significantly compressed, and is then compressed vertically by a tongue (40) to form the desired oval cross-section (with a horizontal major axis); while the filler stream is being vertically compressed by the tongue, the garniture bed (38) allows the radius of curvature of the underneath surface of the filler stream to increase progressively to the final value.

    The invention relates to the tobacco industry, namely the manufacture of oval cigarettes.
    The aim of the invention is to save tobacco by ensuring uniform packing density of tobacco in a cigarette.

    The device comprises a porous or perforated conveyor 1 for forming a flow of tobacco 2, placed on pulleys 3 and 4 and communicated with a vacuum system (not shown) by means of a vacuum chamber 5 for keeping the flow of tobacco 2 on the bottom surface of the conveyor 1. Dip channel 6 passes upward in the direction of the conveyor 1. The headset of the device includes a guide chute and a conveyor belt 7 for the wrapping strip 8 and the flow of tobacco 2 placed on it, moving along the chute. The latter determines the shape of the cross section of the curvature of the conveyor belt | enty 7. A means for shaping the flow of tobacco 2 is installed above the chute. The upper part of the latter is exciting to form an oval cross section of the cigarette

    The visibility of its side walls 10 varies from flat to curvilinear, corresponding to the shape of the surface of an oval cigarette (not shown) to pre-form the upper surface of the flow of tobacco 2 without compaction, and in the headset section, after aligning the centers of curvature, remains constant to seal the flow of tobacco 2,
    It is advisable to carry out a device in which the opposing walls 11 of the filling channel 6 in the zone adjacent to the conveyor 1 diverge in the direction of the latter each at an angle of 7.5-9.5 relative to the vertical,
    The passage 6 has an outlet device 12 with leveling.
    13 and inserts 14 serving to grip the edges of the conveyor belt 7, the flow of tobacco 2 into the gaps between the conveyor 1 and the inserts
    14 prevent the longitudinal airway slits 15 formed between the opposite walls 11 of the first. channel 6 and the walls of the vacuum chamber 5,
    The spiral spring ribbons I b support the opposite edges of the conveyor 1 and move with it.
    The pulley 4 is made hollow to create a vacuum in the zone of the lower bearing of the conveyor 1 to its point of inflection. The side rails 17 of the tobacco forming means 2 limit the edges of the flow of the tobacco 2 during its movement by the conveyor 1 in the area of the pulley 4 and provide the desired shape of the wrapping strip in zone B (Figure 4).
    Removing the flow of tobacco 2 from the conveyor 1 provides bashmak 18, in zone B, bashmak 18 (fig. 5) has a flat bottom surface shape, in zones c and d (figs 5 and 6) its shape changes to a curvilinear (fig.6 and 7) and between zones D and D the surface of the shoe 18 has a constant curvilinear shape. The shoe 18 interacts with the headset cushion 19, the platform 9 and the side walls 10 of which determine the shape of the guide groove (Figures 4-6). Then the flow of tobacco 2 enters the zone of action of the tab 20 of the means of forming tobacco. Reshaping the tongue tab 20 contributes to vertical compaction of the flow.
    tobacco 2 (FIGS. 8-10). The bending of the wrapping strip 8 as the flow of the tobacco 2 compresses with the tongue 20 provides the first bending member 21, When the keeper (not shown) applies the composition to the inner surface of the vertically located leading edge of the wrapping strip 8. The second The folding element 22 is located below the flow of the tobacco 2 and bends the edge of the wrapping strip, covered with adhesive, on the rear edge to form a seam. The latter is fixed by a heater (not shown).
    The device works as follows.
    Under the action of vacuum, the flow of tobacco 2 from the charging channel 6 enters the lower surface of the conveyor 1, the equalizer 13 is removed from the tobacco surplus, and the main flow of tobacco 2 is applied to the wrapping strip. In this case, the conveyor 1 is attracted upward due to the vacuum. The air flows through the slots 15 under the action of a vacuum created in the upper part of the filling channel 6.
    The divergence of the opposite walls of the filling channel allows
    To stream tobacco 2 along the longitudinal axis of the conveyor in such a way that. the edges of the flow that are most strongly subjected to vertical compaction have the lowest density. When the conveyor 1 and the conveyor belt move 7., the turning band with the flow of tobacco 2 placed on it changes its shape in accordance with the shape of the guide groove and the shape of the means for shaping the flow of tobacco 2, the flat bottom surface of the shoe 18 of the forming means moves the flow of tobacco 2 from the flat surface of the conveyor 1 into the chute, the bottom platform 9 of which also has a flat shape. With further movement of the flow of tobacco 2 and the wrapping strip 8, the centers of curvature of the side walls 10 of the chute in the direction of movement the headset conveyor belts converge in direction, one to the other, before they overlap and then increase the radius of curvature to seal the tobacco flow. Preforming the top surface of the tobacco flow is achieved by changing from

    flat to curvilinear inner surface of the shoe of the tobacco forming means from the inlet portion of the chute to align the curvature centers of its side walls 10. As the flow of tobacco passes under the tongue 20, the molding in the vertical direction increases simultaneously the curvature of the lower surface of the stream tobacco 2, wherein the bottom surface of the tongue 20 is displaced downward and the side portions of the flow of tobacco 2 are bent downwards. The packing density of the cigarette rod formed by the flow the tobacco 2, whose width does not change, becomes uniform. As the tobacco flow 2 is vertically compressed by the tongue 20, the rear edge of the wrapping strip 8 is gradually bent over the tongue 20 by the first folding element 21. Simultaneously the front edge of the strip 8 strip put into a vertical position and an adhesive strip is applied to its inside surface;
    composition (not shown). The second bending element 22 bends downward in-; the middle edge of the wrapping strip 8 and presses it against the strip of adhesive composition. The seam is fixed with a heater. The cigarette rod thus formed is oval-shaped. The density of its stuffing increases evenly from the side parts to the middle, which saves tobacco in the manufacture of cigarettes.
    If the opposite walls of the filling channel in the zone adjacent to the conveyor diverge in the direction of the latter each at an angle less than 7.5, the density of the cigarettes is not necessary, which reduces the i-is quality. At an angle greater than 9,5, tobacco saving is not achieved.
    Thus, the proposed device saves tobacco by ensuring uniform packing density of tobacco in the rod by increasing the radius of curvature of the guide chute and the inner surface of the tobacco forming means to match their shape to the surface of the oval cigarette and by diverging the opposite walls of the filling channel adjacent
    to the conveyor at an angle of 7.5 - 9.5 ° relative to the vertical.
