Abstract
A transporting belt is partially held by a holding belt. The holding belt is rolled up into a tubular shape through which both of the forward and return paths of the transporting belt passes. Both of the belts are supported by a plurality of shape-maintaining frames each of which comprises a plurality of shape-maintaining rollers arranged like a circle. The holding belt is provided at a horizontal or vertical curved portion so that the transporting belt may travel smoothly and may not be exposed to the weather.
