<p>This invention depicts a web winding apparatus for winding belt-like materials (webs 20) such as plastic films, paper, thin metallic strips, being slit to a predetermined width by a slitter (12) This web winding apparatus has at least one winder unit (14, 15; 76, 77) detachably mounted to a main body (37) of winding apparatus. The or each of the winder units (14, 15; 76, 77) includes a support beam (36) detachably mounted to the main body (37) of winding apparatus, a plurality of pairs of arms (40) provided on the support beam (36), for holding reels (44) to wind slit webs from opposite sides and winding tension generators (49) provided on the support beam (36) corresponding in number to the reels (44), for giving a winding tension to the reels (44). : There are previously prepared a plurality of winder units (14, 15; 76, 77) with the aforesaid arrangement, having various arm intervals accommodated to the widths of web slits, whereby winder units corresponding to the widths of webs are mounted to the winding apparatus. Since the arms (40) secured to the winder unit (14, 15; 76, 77) are of the stationary type, the winding quality of the product roll is . satisfactory and a change in the width of web (20) can be rapidly accommodated.</p> |
