Abstract
Abstract Continuous form or series-connected envelopes are made by folding an elongated web of sheet material onto itself along at least one longitudinally extending fold line to form a lower ply and at least one upper ply partially overlying the lower ply. The plies are connected in face-to-face relation by a longitudinally spaced series of transversely extending lines of adhesive to form a succession of envelopes having longitudinally extending mouth openings. Lines of weakening are provided along which the envelopes may be separated from each other and from a longitudinally extending marginal connecting strip on the lower ply and opposite the mouth openings. A series of holes or other configurations may be formed in the latter connecting strip for operative engagement with a feeding device and/or a line of adhesive may be applied to the connecting strip for attaching each of the envelopes to an associated article.
