Apparatus for automatically laminating photoresist dry film (52) onto each of a plurality of panels (63) stacked upright in a panel feed unit (16) with a 10 DEG slant counterclockwise from the vertical, the film being easily contaminated, limp and tacky, although peelable, thereby enabling the use of a polyethylene protective coating, includes a film feed bar (28) for pulling the film from a roll (18) into a laminating station (22) on a 10 DEG upward slant, the polyethylene coating being wound on a take-up roll (20). It further includes a film hold bar, a film hold cutoff bar (30) and a film cutoff knife (24) for cutting the film precisely to the length required for folding the film over a panel (62) on both sides with no overlap. A panel pick-up unit (14) picks up each of the panels (62) in succession and moves it down into engagement with a transverse center line on the film (52), through a laminating nip and between heated laminating rolls (26), and delivery belts (50) and cooperating lugs move the laminated panel to delivery stack (44). The film feed, film hold, and film hold cutoff bars, and the panel pcik-up unit include vacuum cups and/or cavities for handling the film and the panels. The sequential operation of the several components is controlled by a microprocessor. |
