Abstract
The variable resist laminator receives a heated panel between two identical vacuum bails and the leading edge of a web of photoresist material is placed on opposite sides of the panel simultaneously prior to feeding the panel and attached webs between a pair of application rolls. Identical cutter mechanisms shear the webs into sheets of the desired length and the length may be varied for different length panels. Vacuum means are provided for maintaining control of the trailing edges of the cut sheets until they are applied to the panel to prevent the formation of wrinkles or other defects due to premature application. Vacuum means is also provided for removing flakes or debris as the webs are sheared. A gated conveyor system feeds the panels and the conveyor system has means for controlling the operation of the vacuum bails, the cutters, and the application rolls.
