Abstract (en)
[origin: EP1018590A2] A thermoplastic spacing bead (7) is applied to a glass pane from a moving extrusion nozzle (1) with guide walls (2,3). At a corner the nozzle is raised slightly to prevent the bead adhering to the glass and is rotated (11) so that the inner guide wall (3) forms a sharp corner (13). The outer guide wall (2) produces a rounded edge (14). Application of the bead (7) then continues in the new direction (15). An Independent claim is also included for producing a sharp corner and smooth join at the final corner by moving the nozzle outwards while in the raised position and taking the bead past the original start point before forming the last rounded outer corner.
