ABSTRACT:
A mailing container having upper and lower plain paper layers padded with at least two layers of globular paper is made with feed and unwinding devices for upper and lower paper webs and an unwinding device for the padded webs. A device connects the paper webs with padded webs adjacent an edge of the mailing containers. A device cuts the mailing containers to a predetermined format. A station for globular paper includes at least one supply roll to be unwound from the upper paper web and a lower paper web. A reactivatable hot melt adhesive is applied along predetermined zones, on at least one of the globular paper webs and on at least one web of the upper and lower paper webs before the webs are brought together. The hot melt adhesive applied to the predetermined zones between the upper and lower paper web and/or between the globular paper webs causes these webs to be permanently joined.
