ABSTRACT:
It is an object of this invention to eliminate the necessity of using pulleys which will bring about cost increase, trouble and reduction of service life, and give rise to the positional irregularity of the coil edge.Two sets of endless belts1are disposed one above the other, each set of endless belts being laterally arranged side by side. Pressure applying members2and3which hold each the endless belts1in a state that the endless belts freely circulate in an oval shape state, press the inner surfaces1aof the endless belts1,and are passed through the inner part of the endless belts1.Each pressure applying member2(3) includes at least a belt pressing part21(31) which has a linear shaped side surface for directly pressing the inner surfaces1aof the endless belts, and belt reversing parts23(33) being arcuate in cross section. A coefficient of friction of an outer surface1bof each the endless belt1is larger than that of the inner surface1athereof to thereby generate a tension in the slit band sheet “a”.
