1. A curved belt conveyor comprising:
a supporting structure having a base for supporting the curved belt conveyor on a floor and a curved top portion engaged to the base, the curved top portion defining at least one curved advancing plane for one or more objects and/or articles to be moved along a curvilinear advancing path and being provided with an arched wide side and an arched narrow side opposite each other; and
an endless conveyor belt operatively engaged to the curved top portion of the supporting structure to define the curved advancing plane of the curved top portion, the endless conveyor belt moving at least partially around at least two revolving rollers rotatively engaged to the curved top portion of the supporting structure;
wherein at least one revolving roller of the at least two revolving rollers is movable with respect to the other roller of the at least two revolving rollers between a relatively distant position, wherein the endless conveyor belt is kept under tension and is not removable from the at least two revolving rollers, and a relatively close position, wherein the endless conveyor belt is loose and removable from the at least two revolving rollers, through the arched narrow side of the curved top portion of the supporting structure;
wherein at least one connection mechanism is operatively interposed between the at least one revolving roller of the at least two revolving rollers that is movable and a corresponding arched side of the curved top portion of the supporting structure, the connection mechanism being switchable between a locking condition wherein the at least one corresponding revolving roller is maintained in the relatively distant position, and an unlocking condition, wherein the at least one revolving roller can be moved between the relatively distant position and the relatively close position.
