In a new machine whichhas just been placed upon the market the rewinding deviceassists in the slitting of the material and the two units ofthe machine have been made inter-dependent. Several innovations have been introduced in this machine,which has already been installed in a number of the prominentrubber factories. The most noteworthy feature is the deviceused to slit the material. Instead of using a pair of rotary full width of the machine and may be raised or lowered bymeans of a cam F in order to bring the cutting wheels intoor out of contact with the steel roller G. This roller is madeof much harder material than the cutting wheels, in orderthat it may not be scored and thus require regrinding. Thecutters C are arranged so that they may be easily removedfor sharpening. In order that the cutters may be pressedagainst the roller G with some force and with a somewhatyielding pre
