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 lin
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.

An apparatus for the precision cutting of material by a single disc-saw, comprising means for supporting a hub (3) of said disc-saw (2) at a first end of said hub adjacent to said saw by at least one pivotable radial bearing (6), and means for supporting a second end of said hub receiving rotation o
An apparatus for the precision cutting of material by a single disc-saw, comprising means for supporting a hub (3) of said disc-saw (2) at a first end of said hub adjacent to said saw by at least one pivotable radial bearing (6), and means for supporting a second end of said hub receiving rotation of a pulley (30) and being operatively connected to a servo-control (10-12-13-113) enabling an axis of said hub to be perfectly aligned with an axis of rotation of said saw and permitting, on command, angular spacing of said axis of said hub from said axis of rotation, with rotation about a center of said bearing (6), whereby upon each rotation imparted to said disc-saw (2), teeth thereof perform a complete oscillation in a transverse direction, with an amplitude proportional to said spacing and to a radius of said disc-saw, and wherein said servo-control comprises a cylinder-and-piston unit (10, 12) with two oppositely-directed rods (13, 113), both of said rods being aligned normally to said axis of said hub and having rounded ends abutting against an inner race of at least one radial bearing (14, 114) which rotatably supports said pulley (30) which drives said hub in rotation by means of a bushing (27) coaxil with said hub and formed with longitudinal opposite slots (28, 128) tranversed by said rods, said cylinder-and-piston unit being of the single-acting type with an internal spring (21), said cylinder-and-piston unit being connected with a pressurized chamber (22) to a rotary joint (24) mounted axially at an end of said hub, said pressurized chamber being selectively connectible with a source of pressurized fluid, said hub being provided with adjustable screws (33, 133) paralled and adjacent to said rods, which screws alternately abut against an inner surface of said busing, whereby, when said cylinder-and-piston unit is at rest, said axis of said hub is aligned with said axis of rotation, and when said cylinder-and-piston unit is activated, said axis of said hub is spaced angularly from said axis of rotation, whereby said disc-saw will be moved in a path of composite movement of rotation and lateral oscillation to effect scoring cuts (H) in said material.
