Abstract: A cloth cutting apparatus comprising a first arm rotatably attached to a pillar arranged movably along a table, a second arm rotatably connected to the top end of the first arm and a cutter attached to the top end of the second arm. The second arm comprises two parallel arm members, both the ends of which are rotatably supported by a supporting member. A cylinder in which a high-pressure gas is sealed is arranged between a supporting member for the first arm and one of said arm members. The position of attachment of a piston shaft of the cylinder at the supporting member is transferable.
