ABSTRACT:
A strip 20 has a drive margin 36 and a latent image of a pattern in a light sensitive coating 73 of a pattern portion 22 thereon. To avoid disturbing the pattern, the strip 20 is gripped by the drive margin 36 using a set 43 of pinch-drive rollers which drive the strip without disturbing the latent image. The strip 20 is driven through pattern development, cleaning and etching solution spray chambers 64, 66 and 108, respectively. One or more adjustable shields 78 are used to vary the time interval during which the strip 20 is sprayed by these solutions. By adjusting one or more shields 78 to suit changes in solution condition the time intervals for proper developing, cleaning and etching are coordinated for a speed at which the strip 20 is driven.
