Abstract

Apparatus is described for automatically applying a photoresist coating to articles contained in carriers serially incremented along a transport path. Input magazine 1 contains a stack of discrete identical carriers 2 each containing an article to which photoresist is to be applied preparatory to exposure to create a desired pattern in the article. From magazine 1, the carriers 2 are incrementally injected onto one of a series of receptacles 3 on an incrementally advanced transport track 4. A film of gummy photoresist is disposed in a laminated supply web 5 between a colored carrier strip 6 and a peelable backup strip 7.

Laminate and Trim Apparatus

Apparatus is described for automatically applying a photoresist coating to articles contained in carriers serially incremented along a transport path. Input magazine 1 contains a stack of discrete identical carriers 2 each containing an article to which photoresist is to be applied preparatory to exposure to create a desired pattern in the article. From magazine 1, the carriers 2 are incrementally injected onto one of a series of receptacles 3 on an incrementally advanced transport track 4. A film of gummy photoresist is disposed in a laminated supply web 5 between a colored carrier strip 6 and a peelable backup strip 7. Web 5 is fed under suitable tension from supply reel 8, then backup strip 7 is removed by winding onto reel 9, while the photoresist coated strip 6 is deflected around roll 10 into a path spaced slightly above and parallel to track 4. As the carriers 2 are incremented along track 4, they are heated; and at successive stations 11, 12, 13, 14 a cam-operated perforating die assembly 15 successively perforates strip 6 longitudinally then transversely, scores it, and optically senses registration. This is preferably accomplished by providing the web 5 with tractor pin feed holes and having a two-stage increment; i.e., a fast advance, followed by a series of small advances under stepper motor control until the optical sensor at 14 detects the trailing edge of the appropriate pin feed hole. With registration thus assured at s...
