ABSTRACT:
Multiple saw blades in a gang rip saw apparatus and like multi-blade cutting apparatus may be selectively adjusted to differing spacings from one another by mounting a threaded sleeve on the rotary arbor of the apparatus and mounting a plurality of electric drive motors on the sleeve with the rotor of each drive motor threadedly engaged with the sleeve and the stator held fixed against rotation relative to the sleeve by longitudinal guide rods, which carry electrical supply wiring to the stators from a slip ring assembly. Each saw blade is affixed annularly to a respective one of the stators. Individual energization of each stator causes the respective rotor to drive the motor/blade assembly along the sleeve to a desired position relative to the other saw blade/motor assemblies. With the saw blade/motor assemblies selectively positioned at desired relative spacings, the arbor is driven to rotate the saw blade/drive motor assemblies integrally with the arbor for "gang" cutting operation in conventional manner.
