<p>1531310 Dispensing extruded cap lining material JAPAN CROWN CORK CO Ltd 24 Nov 1976 [16 Feb 1976] 48984/76 Heading B5A Caps or crowns 10 are each provided with a slug 9 of material for subsequent moulding into a liner, by continuously sequentially conveying the caps or crowns, e.g. by a rotary turret, along a path below an extrusion outlet from which the slugs 9 of extruded cap lining material are sequentially cut and pressed into the centre of each cap or crown, by a blade 4 which continuously rotates across the outlet 8, to approach and depart from the path at a rotative speed which gradually decreases during the approach and gradually increases during the departure. Preferably, Fig. 6, the speed component "x" of the blade along in the direction of the path, is substantially constant and equal to that of the conveying along the path. The decreasing and increasing rotative speed of the blade avoids difficulties that would otherwise occur at a uniform rotative speed, of the radially outer tip of the blade colliding on its approach with a deep skirt 11 of a cap, and of the blade tip having a speed component along the path which is higher than that of the cap and thereby displacing the slug from the centre of the cap. The decrease and increase of speed may be effected by a link or cam mechanism, or as shown by intermeshing non-circular gears 31, 33, driven from a reduction mechanism 21 which also rotates the turret at a gear 25.</p> |
