Abstract
An arrangement for the attachment of a paper web leading edge on a paper supply roll utilizes a rapidly setting material, such as a hot melt adhesive in the form of beads, drops or dots to attach the leading edge of the first paper web layer to the second layer. The drops or beads may bridge the junction of the leading edge with the second layer. Strings or threads, which are attached to the dots of the rapidly setting adhesive, may bridge the juncture.
