ABSTRACT:
A slotter provided with simultaneously two-way rotary saw blades comprises: an input shaft connected to a gear box by a power source, wherein a driving gear is disposed at the end of the input shaft of the gear box, a first driven gear engages with said driving gear and connects with a first driving shaft of which one end extends out of the gear box and retains a first saw blade. Furthermore, a second driven gear engages with the driving gear and connects with a transmitting gear at a second driving shaft, wherein said transmitting gear further engages with a third driven gear which mounted at the outer portion of first driving shaft by using a bearing, a second saw blade is disposed at a bearing seat of third driven gear such that the first saw blade and the second saw blade can simultaneously rotate in the deferent directions, thereby the reaction forces of the first saw blade and the second saw blade can be offset by each other so as to have a stable operation while in use.
