1454506 Delivering filters in orderly arrangement MOLINS Ltd 25 Feb 1974 [26 Feb 1973] 9315/73 Heading A2C Two endwise-moving streams of rod-like articles are caused to move around a conical surface along separate paths which merge and progress spirally towards the lesser diameter end of the surface, the articles in the streams being staggered so as to intercalate as they merge. As shown in Figs. 1 and 2 a wheel 2 delivers to a cone 4 a succession of spaced endwise-moving filter portions A, the axes of rotation of cone 4 and wheel 2 being parallel, one with the other. Similarly another wheel 6 delivers filter portions B to the same cone 4 at a different position on its surface. Filter portions A move initially along a path 12 in a plane normal to the axis of cone 4. The path 14 of the filter portions B is initially in a parallel plane but then bends upwards so as to merge with the path 12 at a point 16. Thus a substantially closed stream of alternating filter portions is delivered tangentially from the top of the cone (by means not shown) onto a continuous wrapper web to form a continuous rod. Further apparatus (not shown) is described to indicate how streams of spaced filter portions may be delivered to the cone.
