Abstract
Automatic registration apparatus for multi-color silk screening of elongated articles, such as writing implements, includes a carriage for rotatably supporting the articles with respect to the longitudinal axis thereof and magnetic means on the carriage for drawing a magnetically attractable index on the article, for example a pocket clip, so that a surface on the article is oriented in predetermined disposition with a pattern in the silk screen stencil. The carriage is also adapted to lift the articles from a high speed conveyor into contact with the silk screen stencil.
Claims10
Apparatus for precisely registering and operating on elongated articles with respect to a silk screen stencil where such articles include a surface symmetrically disposed about the longitudinal axis thereof and a magnetically attractable index contained thereupon, comprising:
- carriage means for rotatably supporting said articles with respect to the longitudinal axis, magnetic means secured to said carriage means for attracting the index and causing rotation of each article until a predetermined portion on the surface thereof is in alignment with a pattern on the silk screen stencil, said magnetic means being positionally located in fixed relation to said carriage means to provide spaced disposition between said magnetic means and said index throughout said registration and subsequent operations on said articles, and
- means to reciprocate said carriage means and said stencil with respect to each other until the surface of said articles abuts said stencil, whereby the stencil may imprint a pattern on each article without interference.
Apparatus for precisely registering elongated articles with respect to a silk screen stencil where such articles include a surface symmetrically disposed about the longitudinal axis thereof and a magnetically attractable index contained thereupon, comprising:
- carriage means for rotatably supporting said articles with respect to the longitudinal axis,
- magnetic means on said carriage means for attracting the index and causing rotation of each article until a predetermined portion of the surface thereof is in alignment with a pattern on the silk screen stencil, and
- means to reciprocate said carriage means and said stencil with respect to each other until the surface of said articles abuts said stencil,
- said carriage means including a preliminary alignment stage and a printing stage, said preliminary stage including pairs of spaced rollers oriented at a first level and said printing stage including sets of spaced rollers oriented at a second level above the first level.
