Abstract
An apparatus for controlling and operating a circular cutting blade with cutting rolls from reels having support element designed to carry a cutting blade, with a first actuating means for rotational actuation of a blade about an axis of rotation, and an assembly (200) for translational actuation of the first support element (124) with respect to the second support element (123) so as to vary the interaxial distance between the orbiting axis (x2) and the axis of rotation (x1) of the blade.

An apparatus for controlling and operating a circular blade for cutting rolls from reels, comprising:
- a first support element designed to carry the cutting blade, allowing rotation thereof;
- first actuating means for rotational actuation of the blade about an axis of rotation (x1) with respect to the first support element;
- a second support element arranged to rotate about a longitudinal orbiting axis (x2) parallel and axially offset with respect to the axis of rotation (x1) of the blade;
- wherein the second rotating support element is coupled to the first support element by means of coupling means so that the two support elements rotate together about the orbiting axis (x2);
- second actuating means for rotational actuation of the second support element about the orbiting axis (x2) such as to move the blade along a predefined circular cutting orbit (O);
- comprising:
- the first support element is coupled to the second support element so as to allow relative translation between the two support elements in a radial direction perpendicular to the orbiting axis (x2);
- and in that it comprises an assembly for translational actuation of the first support element and therefore of the cutting blade with respect to the second support element so as to vary the interaxial distance between the orbiting axis (x2) and the axis of rotation (x1) of the blade depending on a variation (D1-d1) in the diameter (D1) of the blade and/or of the circular cutting orbit.
A method for controlling and operating a cutting blade for cutting rolls from a reel of greater axial/longitudinal length, comprising the steps of:
- arranging one or more reels to be cut with their axes parallel to a longitudinal direction, the one or more reels being arranged tangentially and internally with respect to a circular cutting orbit (O);
- rotationally actuating a cutting blade about an axis of rotation (x1) by means of first actuating means and causing, by means of second actuating means, an orbiting movement of the blade along the circular orbit (O) about an orbiting axis (x2) parallel and axially offset with respect to the axis of rotation (x1) of the blade, so as to cut the rolls from the one or more reels arranged on the cutting orbit (O);
- varying the interaxial distance (dx) between the axis of rotation (x1) and the orbiting axis (x2) of the cutting blade depending on a variation (D1-d1) in the diameter (D1) of the cutting blade and/or of the circular cutting orbit.
