Abstract: A device for manufacturing circumferentially closed tubular tube bodies, comprising conveying means for conveying the substrate in a conveying direction, and also comprising tube-forming means which are designed to form a web-like substrate, which has a first and a second longitudinal edge, into a tubular form in which, in the circumferential direction, the first and the second longitudinal edge form or delimit a contact region, in particular abutting or overlapping region, which extends in the conveying direction, wherein the tube-forming means effect the shaping of the substrate into the tubular form in a shaping region and comprise welding means for welding the tubular form at a weld circumferential position, first sensor means, which are upstream of the shaping region; in the conveying direction, for detecting the position of the substrate web, setting means for setting the position of the substrate web transversely with respect to the conveying direction, and first control means which are designed to act

Abstract: A method for manufacturing tubular bodies (1) exhibiting an inner circumferential surface (8) and outer circumferential surface (7) for packaging tubes out of a strip-shaped film substrate (2), which exhibits at least one weldable plastic layer (3) or consists of the latter, and which encompasses a first edge face (5) extending in the longitudinal direction of the film substrate (2) or a second edge face (6) spaced apart from the first edge face (5) by the width of the film substrate (2), wherein the first edge face (5) runs at a first angle (?) relative to a first thickness extension direction on a first radially innermost border (9) of the first edge face (5), and the second edge face (6) runs at a second angle (?) relative to a second thickness extension direction on a second radially outermost border of the second edge face (6), and wherein the first and second edge faces (6) are placed opposite each other and joined together during exposure to heat, wherein the first angle (?) and second angle (?) differ

Abstract: A method for manufacturing tubular bodies (1) exhibiting an inner circumferential surface and outer circumferential surface (8) for packaging tubes out of a strip-shaped film substrate (2) that encompasses a barrier layer (19) against moisture and/or oxygen, exhibits at least one weldable plastic layer (3), and comprises a beveled first edge face (5) extending in the longitudinal direction of the film substrate (2) and a beveled second edge face (6) spaced apart from the first edge face (5) by the width of the film substrate (2), wherein the first edge face (5) and second edge face (6) are arranged opposite each other with the formation of a tube shape, and welded together during exposure to heat, the first and second edge face (5, 6) are pressed against each other during welding so as to compress the barrier layer (19), accompanied by the formation of a wave geometry encompassing several wave peaks and/or several wave valleys and exhibiting at least three zero crossings and/or at least two equiphase zero cro
