A cutting machine which dispenses and cuts sheet material includes a carriage on rails for movement parallel to the horizontal rolls carried on a vertical carrousel. The carriage supports a cutting table top and a drive roller at one side for driving the roll of floor covering material on the carrousel in forward direction for feeding the sheet to the table top and in reverse direction for re-winding. A measuring wheel and electric eye for detecting the presence of the material are located on the table top. A sensor is provided to detect if the measuring wheel is de-activated during use. A control unit includes a printer and is arranged to cause measurement and feeding of a measured length of the material which is fed to a re-roller on the carriage. When the measured amount is supplied the printer is operated to print a label defining the material and the length but only if the measuring device remained properly active during the measuring process to ensure the length is accurate and not distorted by error or deliberately.
