ABSTRACT:
Each support (14) of a collection drum for printed sheets (24) has attached to it carriages (36) which in the course of a revolution in the direction of rotation (U) carry out a conveyance stroke in and a return stroke opposite to arrow direction (F). Each carriage (36) is provided with swivelable clamping tongues (38) which are controllable by means of rail sections (86) which run parallel to the direction of movement (F) of the carriages (36) and can be moved in the direction (H). This means that the clamping tongues (38) can be closed or opened independently of the position and speed of the carriages (36). Each clamping tongue (38) clamps printed sheet halves (76, 76') of printed sheets (24) placed on the support (14) and on the support (14) following it, viewed in the direction of rotation (U) of this support (14).
