Abstract

This laminator is used to simultaneously apply sheets of photoresist material to opposite sides of a panel. The laminator is provided with a pair of spaced apart rotatable cylindrical laminating drums 1 and 2. Drums 1 and 2 are held by plates 3 and 4 which are pivotably secured on stub shafts 5 and 6. Panel 7 is fed into the proper position between drums 1 and 2 by a reciprocating feed device comprising cylinder 8 with an internal reciprocating piston, cable 9 which is secured to each end of the piston, sheaves 10 and push bar

Photopolymer Resist Sheet Laminator

This laminator is used to simultaneously apply sheets of photoresist material to opposite sides of a panel. The laminator is provided with a pair of spaced apart rotatable cylindrical laminating drums 1 and 2. Drums 1 and 2 are held by plates 3 and 4 which are pivotably secured on stub shafts 5 and 6. Panel 7 is fed into the proper position between drums 1 and 2 by a reciprocating feed device comprising cylinder 8 with an internal reciprocating piston, cable 9 which is secured to each end of the piston, sheaves 10 and push bar

11 having a notch 12 for gripping panel 7. When push bar 11 reaches its limit of travel, the leading edge of panel 7 will be disposed between opposed rubber strips 13. Rubber strips 13 are disposed in diametrically spaced grooves of drums 1 and 2 and protrude slightly beyond the circumference of the drums.

In order to advance panel 7 between the drums, a pair of feed rollers 14 and 15 receive their drive from laminating drums 1 and 2 through intermediate rollers 16 and 17. Each of these rollers is provided with a friction strip which contacts only the extreme end surfaces of the drums. The rollers are mounted for movement with plates 3 and 4 and for independent movement toward and away from panel 7.

The resist material as wound on rolls 18 is a three ply assembly. As it is fed from rolls 18, the topmost layer is wound on take-up rollers 19. The remaining two plys consist of the photoresist material and a protective material. They pass over drums 1 and 2 so that the photoresist material will be disposed in intimate contact with the surface of panel 7. A pair of curing rollers 20 and 21 and heating lamps 22 and 23 are provided to the right of drums 1 and 2 in order to bond the photoresist material to panel 7.

A vacuum is applied to the interior of drums 1 and 2, so that through hol...
