Abstract
This invention provides a cutting device used in making a cut mask, which includes a hollow frame with a lower flat sliding surface and a cutter supported rotatably and with tension by a supporting arm secured to the frame, with the point of the cutting edge of the cutter being offset from the axis of rotation of the cutter that is orthogonal to the lower sliding surface, and which makes it possible to hold the cutter constantly at a set angle under a certain pressure, thereby facilitating the work of cutting.
Claims7
A cutting device for cutting a mask comprising:
- a hollow cylindrical frame defining a central opening and having a lower flat sliding surface;
- a supporting arm secured to the frame and having a distal end positioned over said central opening;
- an elongated cutter including a cutter support secured to said distal end of said supporting arm, a cutter shaft rotatably supported by said cutter support, said cutter shaft having a longitudinal axis of rotation perpendicular to the lower sliding surface;
- resilient means for bearing against said cutter shaft to bias said cutter shaft vertically downward;
- and
- a cutting element secured to said lower end of said cutter shaft, said cutting element having a cutting point offset from said axis of rotation.
