PURPOSE:To smoothly transfer a sheet from a lower belt to an upper one in a conveyance equipment without wrinkling the sheet, by providing suction chambers at the transfer sections of the belts and improvig the position of each suction hole of the lower suction chamber. CONSTITUTION:A sheet conveyance equipment includes a lower belt 8 onto which a sheet 1 is sucked by force applied through numerous suction holes 4 of a lower suction chamber 2 and an upper belt 9 onto which the sheet 1 on the lower belt 8 is sucked by force applied through the suction holes 5 of an upper suction chamber 3, to convey the sheet. The ends of the upper and the lower suction chambers 3, 2 are discrepant rightward or leftward from each other so that the chambers are partly overlapped with each other. The suction holes 4a, which belong to the suction part 6 of the lower suction chamber 2 and are located at its end opposed to the upper camber 3, are placed like V sidewards from the width center of each belt so that the rows of the suction holes 4a are oblique to the direction of conveyance of the sheet 1. |
