Claims

[Scope of Claim for Utility Model Registration] (1) A plurality of short rubber hollow rolls that are open at both ends in the axial direction are arranged in series, and each outer open end of the hollow roll at the start end and the hollow roll at the end are airtightly fixed to the shaft inserted through the opening of the hollow roll via a sealing member, and the opposing open ends of each adjacent hollow roll are airtightly connected via the sealing member, and each hollow roll is An air roll for squeezing and pressurizing, characterized by being provided with an air supply mechanism for filling air into the inside of the roll. (2) On the outer circumference of each hollow roll at both ends in the axial direction,
The air roll for squeezing and pressurizing according to claim 1, which is formed with a bulge that projects outward in the axial direction. (3) A utility model registration request in which each connected hollow roll communicates with each other via a ventilation passage provided in the seal member at the opposing open end, and each hollow roll is provided with a common air supply mechanism. The air roll for squeezing and pressurizing according to item 1 or 2. (4) Seal members at opposing open ends of adjacent hollow rolls are hermetically fitted to the shaft body via O-rings, spacers are interposed between the seal members at each open end, and each hollow roll An air roll for squeezing and pressurizing according to claim 1 or 2, wherein an independent air supply mechanism is provided for each air roll.
