Abstract
A cutting machine for cutting a flat cardboard plate 2 includes first and second rotary cutters 7 and 8 rotatable in respective directions counter to each other for cutting upper and lower portions of a thickness of the flat cardboard plate 2, respectively. The first and second rotary cutters 7 and 8 and the flat cardboard plate 2 are moved relative to each other in a direction conforming to a single cutting line b to cut the flat cardboard plate 2 along the cutting line b. In this way, the flat cardboard plate 2 having a relatively great thickness can be cut with high cutting accuracy.

A cutting machine for cutting a flat cardboard plate having a cardboard, said cutting machine comprising:
- a first rotary cutter for cutting an upper portion of the flat cardboard plate;
- a second rotary cutter rotatable in a direction counter to a direction of rotation of the first rotary cutter for cutting a lower portion of the flat cardboard plate;
- a drive mechanism for driving the first and second rotary cutters relative to the flat cardboard plate along a single cutting line to cut the flat cardboard plate along such cutting line;
- a support table for supporting from below the flat cardboard plate, and a level adjusting mechanism for adjusting a relative position between the support table and the first and second rotary cutters in a direction up and down according to a thickness of the flat cardboard plate to be cut and for setting a boundary between respective depth of cutting by the first and second rotary cutters to a value substantially equal to one half of a thickness of the flat cardboard plate;
- and
- a retaining mechanism for pressing a portion of the flat cardboard plate on a trailing side of the cutting line with respect to a direction of feed of the flat cardboard plate against the support table by moving a retainer bar only in a vertical direction to retain the flat cardboard plate immovable during a cutting operation.
A cutting machine comprising:
- a first rotary cutter operable to cut an upper portion of an article;
- a second rotary cutter which rotates in a direction counter to a direction of rotation of the first rotary cutter and operable to cut a lower portion of the article;
- a drive mechanism operable to drive the first and second rotary cutters relative to the article along a single cutting line to cut the article along such cutting line;
- a support table operable to support from below the article, and a level adjusting mechanism operable to adjust a relative position between the support table and the first and second rotary cutters in a vertical direction according to a thickness of the article to be cut;
- and
- a retaining mechanism operable to press a portion of the article on a trailing side of the cutting line with respect to a direction of feed of the article against the support table to retain the article immovable during a cutting operation,
- wherein the adjusting mechanism is further operable to set a boundary between respective depth of cutting by the first and second rotary cutters to a value substantially equal to one half of a thickness of the article.
A cutting machine comprising:
- a first rotary cutter operable to cut an upper portion of an article;
- a second rotary cutter which rotates in a direction counter to a direction of rotation of the first rotary cutter and operable to cut a lower portion of the article;
- a drive mechanism operable to drive the first and second rotary cutters in a back and forth motion along a single cutting line;
- and
- a support table operable to support from below the article, and a level adjusting mechanism operable to adjust a relative position between the support table and the first and second rotary cutters in a vertical direction according to a thickness of the article to be cut,
- wherein the adjusting mechanism is further operable to set a boundary between respective depth of cutting by the first and second rotary cutters to a value substantially equal to one half of a thickness of the article.
