The 8=shaped cross section is arranged in a wrapping line with an interlacing seam. One interlacing seam (023) at least is designed in the narrowing zone of the 8 shaped section, esp. a pressed stitch seam being provided. With at least one side, pref. on both sides, at least one press connecting seam (03. 03'), formed by a sequence or a row of discrete press connection points (031, 031'), formed by a sequence or a row or discrete press connection points (031, 031') spaced at a distance to each other. Control system can be operated with electric cable. The sequence or row accompanying at a distance from the edges or the edge zones (011, 12, 011', 012") of the original sheets esp. paper webs (00, 010', 010"). The edge zones (011...) lying mutually opposite of the paper webs (010..) have pref. an approximately average width penetrated by inserted lattice like or serrated, at least one single row penetrating connection seam (02) forming connecting openings (021).
