Abstract: Drivable steering axles employed on agricultural traction vehicles already offer the possibility, when the axle drive is disconnected, of completely stopping part of the drive train leading to the wheels of the axle by disengaging two clutch members near to the wheel. However, no satisfactory solution has yet been found for re-establishing the driving connection while the vehicle is moving. An axle which fulfils this requirement, which is very important in agriculture, is provided with a synchronising device which, before bringing them into engagement, stops the two clutch members near to the wheels in a position relative to one another in which the driving teeth of each of these clutch members face the gaps between the teeth of the other clutch member.

Abstract: On a folding jaw cylinder (12), there are provided in each case between adjacent folding jaws (13) flattenings or hollows (18) which can possibly be closed by elastic covers (19). The hollows (18) are arranged in such a manner that, when the folding strips (8) or slotted beams (11) run through the gap (median line A) between the puncture and the folding knife cylinder (6) and the folding jaw cylinder (12), they lie opposite these. As a result, a gap widening virtually takes place so that stoppers or paper accumulations which arise can pass through the gap of the cylinders (6, 12), without one of the cylinders (6, 12) being damaged as a result. At the remaining peripheral regions, a gap widening is made possible by carrying out diameter adjustments (17) in the eccentrically mounted bolt. In the event of a paper jam, these segments can thus yield. In the region of the beams (11) or cutting strips (8) also, a gap widening is then achieved according to the invention when these parts run through the gap by flattenings or hollows (18). <IMAGE>
