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 beltsare disposed one above the other, each set of endless belts being laterally arranged side by side. Pressure applying membersandwhich hold each the endless beltsin a state that the endless belts freely circulate in an oval shape state, press the inner surfacesof the endless beltsand are passed through the inner part of the endless beltsEach pressure applying member() includes at least a belt pressing part() which has a linear shaped side surface for directly pressing the inner surfacesof the endless belts, and belt reversing parts() being arcuate in cross section. A coefficient of friction of an outer surfaceof each the endless beltis larger than that of the inner surfacethereof to thereby generate a tension in the slit band sheet 'a'.
