CHAPTER IX
CUTTING AND CREASING (Continued)
WE HAVE now described the machinery and material which are essential for a modern cutting and creasing plant, and with these matters disposed of we will next take up the subjects of making the steel dies, press-work, etc.
MAKING A CUTTING AND CREASING DIE
No matter what shape or size of a folding box or carton which may be wanted, it will require both creasing and cutting, and this means of course that both steel scoring rules and steel cutting rules will be needed in making the die.
Hard steel cutting rule is to be used for all straight cutting lines in the die.
Soft steel cutting rule is to be used for all round corners or odd-shaped sections of the die.
For the average folding box or carton 2-point cutting and creasing rules will be thick enough for their functions, but in the case of a large die for exceedingly heavy-weight box-board, 3-point, 4-point, or 6-point cutting and creasing rules will be found better for the press-work than the 2-point rules.
The regular 2-point cutting rule, turned upside down, or inverted, will serve as scoring rule, although the special scoring rule, made for this purpose by the manufacturers, will always produce the best results on account of it having a rounded face instead of a blunt face.
