ABSTRACT:
According to the invention a machine is obtained, which is particularly suited for the cutting of blocks of granite (42), wherein the chain-guiding blade (13) with its corresponding chain (75) and a block of granite (42) which is to be cut into slabs roll in a relative motion without skidding.
The place described by the centers of instantaneous rotation (41) is a horizontal line coinciding with the cutting profile (100).
The relative non-skidding rolling motion is conveyed to the chain-guiding blade (13) in one embodiment, while in another embodiment it is conveyed to the block of granite (42) which is being cut.
In order to convey the motion to the chain-guiding blade (13) or to the block of granite (42), there is a mechanical driving mechanism with a template (26) matching a counter-template (6, 81), or hydraulic devices using cylinders (19, 21) with a control device (97), comprising directional valves and proportional valves, or an electro-mechanical mechanism using electric motors with variable speed (63, 64) and racks (51, 52).
