    • PROBLEM TO BE SOLVED: To provide a cutting apparatus capable of preventing a sheet material from moving and being damaged even if a fixed blade receives a resistive force from the sheet material, and preventing the fixed blade from being damaged.SOLUTION: A cutter unit 4 of this cutting apparatus 1 is configured of: a pair of carriages 5 traveling along rails in the longitudinal direction of a cutting table 2; and a cutter head 7 traveling along a rail provided on a beam member 6 between the carriages 5, 5. The cutter head 7 has a rotating blade 29 and the fixed blade 43 that is pressed to the blade edge of the rotating blade 29. The fixed blade 43 is held by means of a fixed blade holder 42, which is pivotally supported to the leading edge portion of a plate spring 40 such that the fixed blade holder 42 can swing, and the fixed blade 43 is held at a cutting position by attracting the fixed blade holder 42 using a permanent magnet 44. When the fixed blade 43 receives an excessive resistive force from a fabric 10, the fixed blade 43 inverts and retracts in the direction opposite to the drive direction of the cutter head 7.
    • 解决的问题:提供一种能够防止片材材料移动和损坏的切割装置,即使固定刀片从片材受到阻力,并且防止固定刀片被损坏。 解决方案:该切割装置1的切割单元4由沿着切割台2的纵向的轨道行进的一对滑架5构成; 以及沿着设置在支架5,5之间的梁构件6上的轨道行进的刀头7.刀头7具有旋转刀片29和固定刀片43,该刀片被压到旋转刀片29的刀刃上。 固定刀片43通过固定刀片保持器42保持,固定刀片保持器42可枢转地支撑在板簧40的前缘部分上,使得固定刀片保持器42能够摆动,并且固定刀片43由切割位置保持在切割位置 使用永磁体44吸引固定刀片保持架42.当固定刀片43从织物10接收到过大的阻力时,固定刀片43沿与刀头7的驱动方向相反的方向倒转。
