The stationary drive station comprises a gear chain guided over three sprocket wheels. One sprocket wheel is driven by a drive motor. A tensioning wheel is rotatably journaled at a pivotably mounted lever acted upon by a tension spring. The tensioning wheel acts on the outer side of the gear chain and on the idle run thereof. The driving run of the gear chain extends at its outer side around part of the circumference of a further sprocket wheel. This further sprocket wheel is seated on a shaft carrying a winding core for winding-up printed products and other flat products. The shaft is journaled in a mobile frame which may be removed from the drive station. The driving connection between the gear chain and the further sprocket wheel can be released by upwardly pivoting a holding or holder structure about the axis of the one sprocket wheel driving the gear chain. The two remaining gear chain-sprocket wheels of the aforementioned three sprocket wheels are rotatably journaled at the holding structure. The driving connection between the gear chain and the further sprocket wheel can be rapidly and positively established and again released. |
