Abstract:
A tire cutting machine comprising:(a) a base; (b) a body member mounted on said base; (c) a drive means assembly mounted on said body member, said drive means assembly having a drive power means, a first drive assembly arm and a second drive assembly arm mounted in colinear relation one to another, a pair of front drive wheels each having an upper arc, said front drive wheels being mounted in a close side-by-side relation on a front drive wheel shaft and positioned between said first drive assembly arm and said second drive assembly arm, a pair of rear drive wheels each having an upper arc, said rear drive wheels being mounted in a close side-by-side relation coaxially to a guide wheel a predetermined distance therefrom, said guide wheel being mounted and engaged to said drive power means with said drive power means being further engaged to said pair of front drive wheels to provide simultaneous rotation of said pair of front drive wheels and said pair of rear drive wheels and said guide wheel; and (d) a cutting means assembly having a cutting power means, a first cutting assembly arm and a second cutting assembly arm mounted in colinear relation one to another, a front cutting wheel having a lower arc, said front cutting wheel being mounted on a front cutting wheel shaft and positioned between said first cutting assembly arm and said second cutting assembly arm, a rear cutting wheel having a lower arc, said rear cutting wheel being mounted and engaged to said cutting power means with said cutting power means being further engaged to said front cutting wheel to provide simultaneous rotation of said front cutting wheel and said rear cutting wheel, said cutting means assembly being vertically disposed above said drive means assembly and positioned with the lower arc of said front cutting wheel passing between the upper arcs of said pair of front drive wheels and the lower arc of said rear cutting wheel passing between the upper arcs of said pair of rear drive wheels such that a tire or tire segment being engaged to said front drive wheels is forced into a positive engagement with said front cutting wheel to impart a cutting force to said tire or tire segment and, similarly, a previously severed tread portion of a tire, said tread portion having been further transversely severed to form a strip, being engaged to said rear drive wheels such that said tread portion is forced into a positive engagement with said rear cutting wheel to impart a cutting force to said tread portion to divide said tread portion into strips of a width defined by the predetermined distance between said rear drive wheels and said guide wheel.
