Claim:
1. A sheet manufacturing apparatus that forms a sheet using a web, the apparatus comprising: an accumulation unit that accumulates the web containing at least a fiber on a first transport belt; a first transport unit that causes the first transport belt to circle around so as to transport the web; a second transport unit that is spaced from the first transport unit in a perpendicular direction perpendicular to a surface of the web, is disposed with a part thereof shifted from the first transport unit toward the downstream side in a transport direction of the web, and sucks the web in a direction in which the web is spaced from the first transport belt and transports the web, the second transport unit including a suction unit that generates a suction force to suction the web, a second transport belt that circles around, a plurality of rollers on which the second transport belt is wounded and which are configured to rotate so as to move the second transport belt, and a suction chamber which is positioned in an inner side of the second transport belt circling around and of which an inner space is sucked by the suction unit such that the web is adsorbed onto the second transport belt, the suction chamber having at least a first part facing the first transport belt and a second part overlapping, in the perpendicular direction, one of the rollers of the second transport unit, the one of the rollers of the second transport unit being disposed most downstream in the transport direction among the rollers of the second transport unit; and a pair of rollers that nips and transports the web, the pair of the rollers being disposed downstream in the transport direction relative to the second transport belt and spaced apart from the second transport belt such that the web is transferred from the second transport belt to the pair of the rollers.
