PURPOSE:To obtain a holder capable of reversing, receiving, and sending papers with high accuracy by using a system in which when the air tube of a bridging cylinder is faced a pressure cylinder on the upstream side, papers are held by a rubber tube and the periphery of the pressure cylinder by expanding the air tube. CONSTITUTION:Air tubes 43 whose both ends are closed are supported by a circular supporter of a ?-shaped cross section and set in the longitudinal direction on the periphery of a bridging cylinder 10 between pressure cylinders 8 and 9. These air tubes are connected with an air source with an air supply tube having a valve on its intermediate joint portion. When the air tubes are faced against the pressure cylinder on the upstream side, air is sent into the air tubes to expand the air tubes 43 toward the radial direction, whereby permitting papers 12 to be held between the air tubes and the periphery of the pressure cylinder 8. Thus, flapping and crumpling toward end of papers when papers are reversed, received, and sent out can be prevented. |
