The method involves using a melting device (7,8) which produces a hot melt adhesive and is carried along with the foil roller (5) during a displacing movement. The melting device is located on a work platform (10) which remains horizontal during the displacing movement. The displacing movement occurs by means of a movement mechanism (4) which has a telescopic arm (12). The swivel axis (11) of the arm is moveably arranged on the support structure. - Independent claims are included for: - (1) a device to attach sheetings to the tunnel wall, and - (2) the use of foamed hot melt adhesive for fixing sheetings to tunnel arches, especially for fixing the sheetings to spray concrete arches. |
