Provided is a system for manufacturing an optical display unit and a feed mechanism, which can well prevent an optical film and a pressure-sensitive adhesive layer from being peeled from a release film. A pressure-sensitive adhesive type sheet material, wherein the optical film and the pressure-sensitive adhesive layer (film main body (F)) are cut without cutting a release film (F12, F22) which is laminated to the optical film with the pressure-sensitive adhesive layer in between, is fed along a feed path (12A, 22A). A press member (200) is arranged at a position opposed to a bent portion or a curved portion in the feed path (12A, 22A). Since the film main body (F) which is peeled from the release film (F12, F22) can be pressed to the release film (F12, F22) by the press member (200), the film main body (F) can be well prevented from being peeled from the release film (F12, F22).
