Abstract (en)
[origin: GB2404898A] Sheet plastics material 18 has a cold-formed crease line formed by positioning over a planar platen surface 16, bringing a rule 4 into engagement with the plastic sheet material 18 and deforming the sheet material between the end of the rule 8 and the platen surface 16, the rule 4 having a main body portion 8 tapering to a rounded tip portion 10, the tip portion 10 having a width of less than 60% of the main body portion 8. Force correcting tape strips less than 25 microns thick are applied, aligned with crease lines to be formed, between a press and a die board mounting the rule 4.
