Press roll apparatus for manufacturing laminated glass

Abstract

A press roll apparatus temporarily or finally bonds two glass sheets with an adhesive intermediate film sandwiched therebetween to manufacture a laminated glass. The press roll apparatus has a plurality of drive roll units each having a pair of upper and lower presser rolls operatively coupled to a drive source and rotatable thereby for pressing the glass sheets therebetween, and a plurality of free roll units each having a pair of upper and lower presser rolls freely rotatable for pressing the glass sheets therebetween. The drive roll units and the free roll units are housed in a frame and vertically positionally adjustably supported by the frame, the frame having a pair of horizontal shafts projecting outwardly. The frame is supported on a support frame by the horizontal shafts for angular movement about the horizontal shafts, the support frame having a pair of horizontally spaced vertical support columns. A pair of vertically movable members is vertically movably supported by the support columns, respectively. The horizontal shafts are tiltably supported by the vertically movable members for angular movement within a vertical plane containing axes of the horizontal shafts.
