Abstract
The method is for manufacturing a tube in which a stretching film is fastened for a length of over one turn on both sides of a tube mesh that is only expandable on a circumference thereof. Each film is also fastened to itself. An expandable tube is formed which is expandable to a circumference allowed by the tube mesh.
Claims10
A method for manufacturing a tube, comprising the steps of:
- positioning a tube mesh that is expandable in a circumference of the tube mesh on a mold, fastening a first stretching film to the tube mesh and around the tube mesh as a tube of over one turn in such a manner that the first stretching film is also fastened to the first stretching film,
- removing a formed tube from the mold, turning the formed tube inside out in such a manner that the first stretching film remains on an inner surface of the formed tube and the tube mesh on an outer surface of the formed tube,
- positioning the formed tube on the mold,
- fastening a second stretching film to the tube mesh and around the tube mesh as a tube of over one turn in such a manner that the second stretching film is also fastened to the second stretching film, whereby a tube is formed with the tube mesh disposed between first and second stretching films.

A tube comprising:
- a first film forming an inner surface of the tube;
- a second film forming an outer surface of the tube;
- a tube mesh disposed between the first film and the second film in such a manner that said first and second films are fastened to the tube mesh;
- the first and second films being at least partly detached from each other and the tube mesh being made up of longitudinal threads of the tube mesh and threads encircling the tube mesh,
- the tube mesh being fastened to the first and second films in such a manner that the tube mesh prevents a longitudinal stretch of the tube, but allows a circumference of the tube to stretch to a limit value, in which the threads encircling the tube mesh have straightened between the first and second films and prevent the tube from stretching further.
