摘要： Means and method for spreading cloth on a moving support surface from a roll or bolt of cloth with a negligible amount of tension on the cloth to cause the cloth to lie flat. The cloth is rolled off the bolt into a slack loop where sensing means determine the extent of the loop and generate signals to control the dispensing of cloth off of the roll into the loop. The cloth is then pulled out of the slack loop over a smooth surface onto the surface of a belt by the mere friction between the cloth and the belt, the tension in the cloth on the belt being minimal, thereby avoiding forming of tension wrinkles in the cloth.

摘要： In a laser cutter, cloth to be cut is advanced to enter the cutting area by means of a conveyor. The conveyor is advanced in steps, stopping before each cutting operation. Deviations of the actual stopping positions of the conveyor from its nominal stopping positions are compensated for by appropriately modifying the cutting path followed by the laser beam.
摘要翻译：在激光切割机中，要切割的布料通过输送机进入切割区域。输送机逐步前进，在每次切割操作之前停止。输送机的实际停止位置与其标称停止位置的偏差通过适当地修改跟随激光束的切割路径来补偿。
