ABSTRACT:

PRIOR ART
The invention relates to an unwinding machine. In a known unwinding machine, the forming cylinders are disposed in stationary bearings and are directly coupled to their drive mechanism. As a result, the axial distances between the forming cylinders are predetermined so that the unwinding machine is only suited for a particular format range. Therefore an adaptation to another format range, if it is even possible, can only be executed through costly retrofitting work.
ADVANTAGES OF THE INVENTION
The unwinding machine according to the invention, has the advantage over the prior art that it is suited to cover a very large format range without costly retrofitting work. This is permitted by means of bearing blocks exchangeably disposed on the machine, wherein the forming cylinders supported in the bearing blocks are coupled to their drive mechanism via articulating elements. It is therefore possible to couple bearing blocks with different distances between the individual forming cylinders in module fashion onto the unwinding machine.
Other advantageous improvements of the unwinding machine according to the invention are disclosed in the dependent claims. The exchanging and fastening of the bearing blocks in the unwinding machine can be achieved in a particularly simple and reliable manner if the bearing blocks are partially received in a form-fitting, positively engaging manner in corresponding recesses in the unwinding machine and can be secured by means of a clamping device.
