(Cl. 131—39) This invention is for improvements in or re lating to. cigarette making or like machines, such for example as tobacco packaging machines, and refers more particularly to a method of and 5 means for feeding tobacco to such machines. It is an object of the present invention to pro vide a method of, and‘ means for, feeding to bacco whereby the individual weights of ciga rettes produced by a cigarette making machine 10 is greatly improved. The tobacco feeding apparatus referred to particles of tobacco contained in the stream are mixed with the lighter particles of an adjacent stream. " In another form according to the present in‘ vention there is provided tobacco feeding appa ratus of the type described, wherein means are provided to impart to the tobacco showered to wards the moving surface, a component of move ment in a direction which is opposed to, the di rection of movement of the moving surface or 10 opposed to the direction in which the surface herein is of the type in which elements are ar when provided is to be moved. ranged to feed tobacco towards‘a surface con In another form’ according to the present in vention there is provided tobacco feeding appa tinuously moving in one direction, said tobacco ' .15 being fed in a shower the width of which‘ extends ratus of the type described wherein means are 15 in the direction in which the surface is moving. The moving surface is not of itself necessarily a part of the tobacco feeding apparatus, but may form a part of the machine to which the tobacco disposed above the moving surface and in the path of the shower and‘are remote. from the sur face or arranged‘ to be remote from where the surface is to be, by a distance such that‘the to bacco is delivered from said means to'the moving 20 feeding apparatus is to be attached. It has previously been proposed in tobacco ‘surface in a manner hereinafter set‘ forth. The feeding apparatus for use with cigarette making means may ‘comprise elements ‘inclined to‘ the machines to feed tobacco towards a moving sur component of movement imparted by the said means to the falling tobacco. cross-section. disposed as near as possible to the moving surface in order to. obtain the maximum bene?t of the 35 direction of fall of the shower, and ther‘elem'ents ‘may consist of ‘plates or vanes which are are ranged such that adjacent plates or vanes ‘have at least those portions'thereof which are near est the moving surface or the place at which the surface is to be formed or staggered’ with respect to each other for a purpose hereinafter speci?ed. The ends of the elements nearest‘ the 30 moving surface or the place at which the sur face is to be, may be substantially parallel there to, and the elements may have a trough-like face in a shower, the width of which extends 25 in the direction of movement of the surface, and to provide means disposed above the moving sur face and in thepath of the shower to impart to the falling tobacco a component of movement in the direction of movement of the moving surface. 30 In such cases, however, the said means have been ' According to one form of the present inven tion, there is provided a method of feeding to bacco to a cigarette making or tobacco packaging machine by showering particles of tobacco to wards a surface moving continuously in one di rection, the particles forming a shower thewidth of which extends lengthwise of the moving sur face, sub-dividing the shower along its width,‘ forming the sub-divided portions’into streams, diverting the direction of fall of the streams and 45 delivering the streams to the moving surface from points disposed above and remote there from by a distance such that the combined widths of the streams as they engage the moving sur face or the tobacco contained thereon is greater O than the total width of the shower. The streams may‘ also be delivered to the moving surface with a component of movement in the direction of movement of the surface.v The streams may be delivered to the surface .55 in staggered arrangement, whereby the heavier The tobacco feeding‘ apparatus, as just described, may be used in combination with a cigarette making machine or‘ a tobacco packaging machine. 35 . In another form the invention consists in a cigarette made in accordance with the method 40 ‘or by the machine just described; In a still further form, the invention consists of tobacco packaged‘ in accordance ‘with the method or by the machine just described. > The invention will ‘be more particularly de scribed by way of example with reference to the accompanying drawings, in which:-— Figure 1 shows diagrammatically a sectional elevation of tobacco feeding apparatus con structed in accordance with the invention. Figure 2 is a sectional end elevationlooking 50 in the direction indicated in Figure 1. Figure 3, is a perspective view showing a por tion.of Figure 1. _ ' Figure 4 is a diagrammaticplaniview of a por tiOn of Figure 1, showing the manner in which 2 2,095,150 streams of tobacco are delivered to a moving sur face. Like references refer to like parts throughout the speci?cation and drawings. Referring to the drawings, tobacco is fed by any suitable known means from a hopper (not shown), and is deposited upon the surface of a distributor roller I, from which it is picked by’a~ picker roller 2, and formed into a shower which 10 is directed towards a surface 3 moving continu ously in one direction. In the example given the moving surface 3 comprises a web of cigarette paper moving on the bottom of a' trough 4 which may, if desired, form the moving surface, so that 15 it has a U-shaped cross-section, as illustrated more clearly in Figures 2 and 3. It is to be understood that the terms‘ “moving surface” and “travelling web” as employed herein are not limited to a web of cigarette paper. 20 Obviously the surface or web may be comprised by other means, for example an endless tape or band, ‘or other conventional form of conveyor. Above the moving surface 3 and in the path of ‘the shower of tobacco there is disposed a number ly perpendicularly from the ends of the bent ends 6. From the foregoing description and by refer— ence to Figure 4, it will be seen that the sum total of the lengths ‘l of the‘ stream will be greater "a than the overall, width of the shower from which streams were formed. It follows, therefore, that the tobacco taken from the shower is spread over a greater surface than has hitherto been the custom, and further, that due to the arrangement of the ends 6 of the plates or vanes, the light and heavy particles of tobacco from the shower are more evenly mixed than is the case when using the known types of tobacco feeding apparatus. Although for the purposes of illustration the lengths ‘l are shown in Figure 4 as being isolated, it will be understood that the streams are nor mally delivered to the tobacco which is carried by the moving surface and that the streams only the direction of movement of the moving surface have the appearance shown in Figure 4 if the 20 view is taken at a point just above the moving surface. The purpose of Figure 4 is merely to show the manner in which the streams fall from the ends of the plates or vanes and in which the light and heavy particles are mixed. For in 25 stance, each of the rows of tobacco particles 3, as shown clearly in Figure 1. The plates or shown in this ?gure represents diagrammatically 'vanes 5 are arranged to sub-divide the shower along its width, and to form the sub-divided 30 portions into streams which slide down the sur the manner in which tobacco is projecting on the moving surface at a given instant by each face of the plates or vanes and are delivered from the ends 6 of the plates or vanes, which are component of movement in the direction of move ment of the surface by reason of the forward in clination of the vanes and a component of move ment transverse to the direction of movement of the moving surface by reason of the fact that the lower ends of the vanes are bent or set askew, so 25 of plates or vanes 5 which are inclined towards bent in the direction in which the conveyor is moving, as shown clearly in Figure 1. The por tions 6 are bentso that they are substantially parallel with the moving surface, and the stream of tobacco, as it leaves the ends of the plates or vanes therefore moves in a substantially horizon tal plane. 40' ' ' The portions 6 of the plates or vanes 5 are ar ranged above the moving surface 3 and remote from the surface by a distance such that the tobacco’ in falling on to the moving surface or on to the tobacco carried thereby, is caused to 45 spread lengthwise along the surface. The distance by which the ends 6 of the plates or‘ vanes 5 are remote from the moving surface is su?iciently great that the length '1 of the mov ing surface over which the tobacco is spread is 50 greater than the width 8 of the shower from which the stream was formed. By this means, tobacco from the shower tends to be more evenly spread on the surface of the moving surface 3 than is the case when the tobacco is-showered 55 on to the moving surface by any of the previously known methods. ' ' a a - The plates or vanes 5 may be of semi-circular or trough-like construction, as shown in Figure 3, to facilitate the forming of the streams, and the .60 ends 6 of the plates or'vanes may be set askew or bent as shown in Figure 3,’so that the streams being delivered from adjacent plates or vanes do not impinge on'ea‘ch other, but the light portions of tobacco 9 from one stream are delivered onto of the vanes, the tobacco particles being given a 30 that the tobacco particles are in effect projected diagonally across the moving surface. If desired, the moving surface 3 may be moved in a direction opposite to that indicated in Figure 40 l, and in this way the tobacco delivered to“ the moving surface is given a component of move ment in a direction which is opposed to the direc tion of movement of the moving surface. It is found when running cigarette making ma 45 chines at speeds producing cigarettes of 70 m/m length at the rate of over 1000 per minute, that the tobacco showered on to the moving surface tends to bounce upwardly from the moving sur face owing to the increased speed at which the 50 tobacco is thrown down by the picker, thus dis turbing the formation of the tobacco on the mov ing surface. By directing the tobacco towards the moving surface in the manner just described, that is to say, by the use of means which alters 55 the direction of downward movement of the tobacco and imparts a component of movement thereto in a direction more nearly horizontal, as by the bending of the lower ends of the. vanes, the tendency for the tobacco to bounce is re duced, and therefore, there is less disturbance of the formation of the tobacco on the moving surface. With the arrangement just described the plates 65 an area of the conveyor adjacent in a transverse or vanes may, if desired, be arranged above the direction to that of the heavy portions ll] of tobacco from the adjacent stream, so that when moving surface at a sufficient height and formed and staggered as above described to spread and mix the particles of tobacco. the tobacco is formed into a rod, the light por tions 9 become mixed with the heavy portions in. 70 It will be appreciated that the heavier por tions Ill of a stream will be carried a greater dis tance in a forward direction as the stream leaves theends 6 of theplates or vanes than will-the 75 lighter portions 9, which tend to drop substantial Tobacco feeding apparatus for cigarette mak ing machinesor tobacco packaging machines is 70 often built separately from the other parts of the machines, and in such instances the trough 4 and moving surface usually form'a part of the main portion of the machine and are not combined with the tobacco feeding apparatus until the 75 13 32,0 95'; 1'5 0 ‘ latter is>_?xed‘ to'the ‘machinei "'It'is to be under determined path, of‘ means‘for discharging! loose stood,’ however,‘ that tobacco feeding ‘apparatus tobaccoiluponi said web in a directionvhaving a ' constructed in‘ accordance‘ with the‘presentl in; component in the direction of movement of the vention need not have the; trough. and moving web, said last named means including a plurality ‘surface combined in the tobacco". feedingfappa ratus since it is a simpleImatter'to arrange: the of stationary elements. spaced. longitudinally of means ‘(e g.,?the plates or vanes) which are dis posed» above the \‘moving'surface and in the path of the shower so that when the-apparatus is com 10 bined with a machine having a moving surface it functions in the manner above described.
