ABSTRACT:
A method for producing a photo album page composed of superposed panels of transparent polypropylene film joined together by parallel lines of adhesive to define channels, each of which is divided by a paper strip into front and rear compartments to accommodate photos. To make photo album pages of this type, two webs of polypropylene film are concurrently advanced into combining rolls. Applied to the inner surface of one of the polypropylene webs are parallel lines of hot-melt adhesive whose chemistry is such that it has an affinity for polypropylene. When the webs are adhered together in the combining rolls, the lines create a plurality of channels. Also concurrently fed into the combining rolls in the spaces between the lines are a like plurality of paper tapes, whereby emerging from the rolls is a composite web which is then slit into individual album pages.
