Abstract:
A method of making cushioning dunnage comprising the steps of:providing an elongated band of stock material having lateral edges and a longitudinal axis, the band of stock material being formed from at least two elongated paper webs, at least one of which is made of Kraft paper, adhered together along the lengths of the webs by glue applied to one of the webs in a gluing area having a length along a longitudinal axis of the one web and a width transverse to the one web longitudinal axis, the transverse location of glue applied to the gluing area varying as a function of the longitudinal location along the gluing area in order to avoid forming a straight line of glue parallel to the longitudinal axis of the one web; driving the band longitudinally; folding the lateral edges of the band laterally inwardly; alternatingly crumpling the band longitudinally on first one side of the longitudinal axis of the band and then on the other side of the longitudinal axis of the band to form pleats in the band; and connecting the pleats in the band by compressing the band through the thickness of the band.
