<p>For striping pencils, paint is extruded through die orifice in the walls of a passage through which the pencil is advanced longitudinally. The orifices are formed in lands which engage corresponding side regions of the pencil and guide the pencil through the passage. The passage is formed in a block having parts that are supported for relative movement along guide rods and are usged together resiliently. Each block part may have at least one paint reservoir with a duct extending from the reservoir and terminsting in a die orifice. The paint, which is supplied to the reservoirs under pressure from a separate source, moves longitudinaIly of the pencil in shallow channels as it issues from the orifices and spreads laterally to an extent depending upon viscosity of the paint, forming stripes of width greater than that of the orifices.</p> |
