ABSTRACT:
An apparatus for unwinding a roll of a thin belt-like discrete sheet material (hereinafter referred to as a "web") including paper, plastic film, fabric, metal and the like includes a cutter mechanism for cutting the forward end portion of the web of the web roll with the core and the forward end portion of the web being previously fixed in the winding direction, a nip mechanism for clamping the forward end portion of the web after the web is cut, and an unwinding shaft to be coupled to the core of the web roll, the cutter mechanism and the nip mechanism together with the unwinding shaft being linearly movable to and from a web roll storing position. The unwinding shaft position is movable, while the web roll supply position is stationary, so that the space for installing the apparatus can be minimized. Furthermore, the apparatus has a nip mechanism for clamping the forward end of the web, whereby the web roll can be delivered in a state where the forward end of the web is clamped.
