Abstract (en)
The ceramic tile cutter is of the kind comprising at least a bridge guide, provided with device for weakly and heavily fastening the piece of tile to score and fracturing it, respectively, wherein the bridge guide (2) has fixed position at one end and is self adjusted at the other end. Such self adjusting is provided by a suitably shaped cam (40') engaging such bridge guide (2) with its operative contour, which is in the form of an exponential spiral defined by the following formula: <MATH> b = minimum resistance arm (to be established experimentally); Bn = maximum weight arm (to be established experimentally); n = number of (arbitrary) cam segments or alpha angle sections; alpha = angle of amenability (to be established experimentally); b; B1; B2; B3;.......Bn = Arms of weight; r; R1; R2; R3;.......Rn = Points of weight.
