PROBLEM TO BE SOLVED: To provide a folding apparatus of a type having a simple structure and improved operation flexibility. SOLUTION: The folding apparatus comprises: a feed unit (10) for supplying a medium (44) to be folded; a folding substrate (12, 12', 62) forming a convexly curved support surface for the medium (44) and adapted to be driven back and forth in the circumferential direction of the support surface; and a pinch and guide structure (14) for folding and guiding the medium (44) on the support surface. The pinch and guide structure (14) comprises at least one endless belt (28) which is arranged to have a belt portion (28a) held in mating engagement with a portion of the curved support surface.
