Abstract
A web transport device transports a web wound on one shaft to the other shaft by rotatively driving the shaft on the take-up side and causing the shaft on the supply side to be driven. When it is desired to stop the feeding of the web, a brake is applied to the shaft on the take-up side and the shaft on the supply side and during the braking, the brake applied to the shaft on the supply side is temporarily released for a predetermined time, whereby slack of a predetermined amount or more is formed in the web between the two shafts. To prevent the instability of the stopped position caused by the formation of such slack, web guide members adapted to bear against the web are provided along a web feeding path.
