摘要

PROBLEM TO BE SOLVED: To provide a web conveying device in which a plurality of rolled raw sheets can be set.SOLUTION: A web conveying apparatus includes: a first feeding shaft; a second feeding shaft having a hollow space; a toroidal type non-stage transmission arranged in an opposite side of the first feeding shaft with respect to the second feeding shaft; and nip rollers. The toroidal type non-stage transmission includes: an input disc; an output disc; a pair of power rollers arranged between both discs; and power roller shafts for pivoting the pair of power rollers. The first feeding shaft and the second feeding shaft are coaxially arranged, and one of the two discs of the toroidal type non-stage transmission has a hollow space and connected with the second feeding shaft. The first feeding shaft extends through the hollow space of the second feeding shaft and the hollow space of the disc to which the second feeding shaft is connected, and connected with the other disc, and the power roller shafts are connected to a drive shaft and revolves by rotation of a drive shaft.
