Beschreibung
Zusammenfassung:	A method of cold forming a crease line in a sheet plastics material (14) is disclosed which comprising the steps of positioning the sheet material (14) over a planar platen surface (2), and forming the crease line by bringing a scoring rule (4) into engagement with the plastic sheet material (18) and deforming the sheet material between the end of the rule (4) and the platen surface (2) L'invention concerne un procédé de formage à froid d'une ligne de pliage dans un matériau plastique en feuille (14). Ledit procédé consiste à positionner le matériau en feuille (14) sur une surface d'appui plane (2) et à former la ligne de pliage en amenant une règle (4) en contact avec le matériau plastique en feuille (18), puis à déformer ce matériau en feuille entre l'extrémité de la règle (4) et la surface d'appui (2).
