Abstract

PURPOSE:To provide widened transport of thin sheet by furnishing a sheet guide groove at the drum of a roller rotating, partitioning inside the roller into a decompression chamber and a pressurization chamber, and by furnishing suction holes and a cold wind jet in the decompression chamber side drum wall and the pressurization chamber side drum wall facing the guide groove, respectively. CONSTITUTION:A partition plate 13 provided with a vacuum suction port 11 and a cold wind jetout port 12 partitions a hollow fixed shaft 1. A roller 2 is borne by this hollow fixed shaft 1 rotatably, and its drum is divided into two sub-drums 21, 22, whose insides are formed as a decompression chamber 3 and pressurization chamber 4, respectively, to be put in communication with the suction port 11 and jetout port 12. A sheet guide groove 5 is provided in the circumferential direction in the middle of the drum of roller 2. A number of suction holes 212, 213 and cold wind jets 222 are bored in those drum walls 211, 214 of sheet guide groove 5 situated on the decompression chamber 3 side and the drum wall 221 on the pressurization chamber 4 side. Therefore, the sheet end guided 10 is moved while sucked and also is cooled to ensure widened transport of a weak thin sheet.
