| 摘要 |
Sheet-carrying disc assembly for a sheet transfer drum carried by a shaft includes a sheet-carrying disc mounted on the drum shaft, a multiplicity of sheet-carrying elements radially adjustable into operative and inoperative positions on the disc, the sheet-carrying elements being constructed as bar-shaped paper carriers disposed at the periphery of the disc, arresting means disposed on the sheet-carrying disc for releasably locking the sheet-carrying elements in the operative and inoperative positions thereof and spring means yieldably biasing the sheet-carrying elements in axial direction of the drum shaft into locking engagement with the arresting means in the operative and inoperative positions of the sheet-carrying elements, each of the bar-shaped paper carriers having a longitudinal axis and being tiltable against the bias of the spring means out of the arresting means about a tilting axis extending in the plane of the sheet carrying disc transversely to the longitudinal axis.
