ABSTRACT:
A plate cutting device is provided which is capable of being used to cut a plate along a curve. It is a design directed to the disadvantages such as labor-consumption, awkwardness, incapability of cutting along a curve, and incapability of cutting a large size plate of conventional cutting tools.
The device is characterized in that it comprises a body associated with a curved frame, a toothed rolling wheel, and a cutting wheel. The two wheels are arranged slantly and are at a small distance from each other.
In plate work, a plate with a line drawn on it is put between the wheels and the ratchet rotating wheel above the rolling wheel is swung such that the toothed rolling wheel is rotated in the same direction and the teeth thereon grab into plate and cooperate with the cutting wheel to cut the plate. The cutting direction can be controlled simply by moving the plate in a suitable direction.
