Normally these machines are between 12" to 36" wide and utilize cantilevered shafts throughout the machine. They are commonly used in the label industry to inspect rolls and sometimes have sophisticated equipment to detect print skips, splices, or things of that sort. They are also commonly used by converters to rewind poorly wound rolls or ever to slit rolls into narrower widths. The cantilevered feature aids in ease of operation and these machines can be equipped with score, razor, or shear slitting.
