Abstract

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.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 155 words
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.
Claim 2
Dependent Claim 155 words
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.
Claim 3
Dependent Claim 23 words
The apparatus of claim 1 wherein said carriage means includes pairs of longitudinally spaced rollers for engagement with the surface of said articles.
Claim 4
Dependent Claim 54 words
The apparatus of claim 2 including a conveyor means for transporting said articles one at a time to a position over said carriage means, and said means to reciprocate causes said carriage means to lift said articles one at a time up from said conveyor means and into contact with said silk screen stencil.
Claim 5
Dependent Claim 25 words
The apparatus of claim 3 wherein said conveyor means comprises a pair of laterally spaced chains transporting said articles transversely to the longitudinal axes thereof.
Claim 6
Dependent Claim 16 words
The apparatus of claim 4 wherein said conveyor means is intermittently actuated in regularly spaced intervals.
Claim 7
Dependent Claim 32 words
The apparatus of claim 5 wherein a plurality of silk screen stencils are longitudinally spaced along said conveyor means, and one carriage means being mounted opposite each of said silk screen stencils.
Claim 8
Dependent Claim 19 words
The apparatus of claim 5 wherein said carriage means is reciprocated during the dwell period of said conveyor means.
Claim 9
Dependent Claim 18 words
The apparatus of claim 7 wherein said carriage means includes a preliminary alignment stage and a printing stage.
Claim 10
Dependent Claim 26 words
The apparatus of claim 8 wherein said preliminary stage includes pairs of spaced rollers oriented at a lower level from the rollers of said printing stage.
Claim 11
Dependent Claim 149 words
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.
Claim 12
Dependent Claim 149 words
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.
