摘要： A cutting machine for fabrics, comprising a table, a carriage reciprocating along the same, a pivoted cantilever extending above the table and having an inner arm pivotably mounted about a vertical axis on the carriage and an outer arm articulated on the inner arm, a hand cutter being pivotable about a vertical axis on the outer arm, further comprising switching means for the carriage drive and for controlling the direction of travel of the carriage, a first switching means being provided which is controlled by both arms in order to limit the deviations of the angle formed by the two cantilever arms from an angle of 90.degree., a second switching means controlled by the inner cantilever arm also being provided to limit the deviations of the angle formed by the inner cantilever arm and the direction of travel of the carriage from an angle of 90.degree.. This ensures that when the carriage is started the forces thus occurring at the hand cutter or its guide handle do not interfere with the cutting operation and do not produce any incorrect cuts.
