In various embodiments, a feeding device may comprise a support having feed cylinders arranged in a free end of a respective supporting arm and driven in rotation, wherein the supporting arms in a supported end are journalled in the support on shafts extending in parallel with each other and are pivotable about the shafts between a home position and a pivoted work position, and wherein the supporting arms are mutually connected to each other via a system of articulated links and by means of the links are forced to pivot jointly about their respective shafts, and a movement damping element, which is separate from the support, is integrated in the system of links and independently from the support configured to brake the return movement of the supporting arms from the pivoted position.

Method (500) and calculating unit (620) for curve sawing of a block (100) in a cutting direction (S) with at least a first circular saw blade (110). The method (500) comprises determining (501) a radius (R) of the curve sawing, by measuring the curvature of the block (100) in the direction of cutting (S); calculating (502) a vertical inclination angle (ß) of the first circular saw blade (110) in a vertical plane (V) relative to the cutting direction (S) in the block (100), based on the determined radius (R) of the curve sawing; inclining (503) the first circular saw blade (110) with the calculated (502) vertical inclination angle (ß); and sawing (508) the block (100) in the cutting direction (S) with the inclined (503) first circular saw blade (110) along the determined (501) radius (R) of the curve sawing.
