ことを特徴とするシート材切断装置である。Means for Solving the Problems According to the present invention, at least one of the blades is disposed so as to cross-contact with each other, and at least one of the blades is a pair of rotary blades or a plurality of pairs of blades or a pair of blades including cylindrical blades. ,
It has a carry-in roller pair that presses through the sheet material to be cut,
One of the carry-in roller pair is a roller that rotates coaxially with the blade that is rotationally driven, and the other is smaller in diameter and diameter than a blade that pairs with the blade that is rotationally driven by a rotatable roller. An axial center is disposed in front of the cutting direction, and the point of pressure contact passes through a contact start point of the blade pair in the plane of the sheet to be cut, and is close to a vertical line perpendicular to the cutting direction. Is a sheet material cutting device.

り、送りローラにより切断時のシート材を拘束ができ、
切断時の材料の蛇行をなくすことができる。By pressing the conveyance roller on a perpendicular line to the cutting direction of the sheet material to be cut with respect to the contact start point, the sheet material at the time of cutting can be restrained by the feed roller,
The meandering of the material at the time of cutting can be eliminated.
送りローラの上記接触開始点に対する位置は、切断方
向前後に5mm以内であれば許容できる。The position of the feed roller with respect to the contact start point is acceptable if it is within 5 mm before and after the cutting direction.
送りローラを上記切断開始点に対して、わずかに切断
前側にすることは、切断開始点より前に材料を拘束でき
るため、切断時に蛇行しやすい材質を対象とする場合好
ましい。It is preferable to set the feed roller slightly before the cutting start point with respect to the cutting start point, since the material can be restrained before the cutting start point, and therefore, it is preferable to use a material that is likely to meander at the time of cutting.
