ABSTRACT:
The hub (3) of the circular or disc-saw is supported, at the end adjacent to the saw, by at least one swingable radial bearing (6), while at the opposite end, driven for rotation by the pulley (28), the hub is supported by a servo-control (10-12) by which the axis of the hub can be maintained in line with the axis of rotation or said axes can be spaced apart angularly by rotation about a common point thereof, whereby the teeth of the saw will have a composite rotational movement and symmetrical side oscillation, with a frequency proportional to the rotational speed of the saw and with an amplitude proportional to the spacing of the axes and to the radius of the saw. The saw is used to score the panels which are subsequently cut through by the saw while being driven only in rotation.
