<p>An apparatus for dispensing predetermined amounts of lining material into cap shells, particularly of the deeply recessed type, includes a conveyor including a passage for conveying cap shells at predetermined speeds, an extruder provided above and along the shell-conveying passage for extruding predetermined quantities of a lining material through a discharge passage, a blade fitted adjacent to the exit end of the discharge passage and rotatably across it for cutting the lining material, and a drive for rotating the blade in response to the conveying of the cap shells. The drive is adapted to rotate the blade at a non-uniform speed in response to the speed of shell conveyance so that its speed gradually decreases as the exterior end of the blade in its radial direction approaches the shell-conveying passage, and gradually increases as it departs from it, whereby collision between the tip of the blade and the cap shells can be completely avoided.</p> |
