Verfahren und Vorrichtung zum Bilden von Falzlinien in kontinuierlich geförderten flachen Werkstücken |
摘要 |
Continuously fed flat workpieces 14 have indentations 15 forming fold lines pressed into the workpieces with a scoring tool, wherein the fold lines 15 are marked only in the zones of their ends. Apparatus for forming the fold lines comprises a cutter-type ridge rotating on a cylindrical cover shell 11, which presses the indentations 15 into the workpieces 14 supported on a roller 18 with an elastomeric shell. The invention is particularly used for forming the bottom fold lines in cross bottom sacks or bags manufactured from transversely fed tubular sections. |
