Abstract
Abstract There is disclosed a fully automatic winding device for winding material in ribbon or strip form, particularly strips or ribbons made of metal foil for producing tightly wound rolls of such material. The device comprises at least one take-up spindle and at least one take-up spool for winding the material thereupon. The device further comprises a pressure roller for pressing already wound-up material against the underlying windings of the material or against the spool itself. The take-up spindle is journaled freely rotatable and floating. It is driven by the pressure roller which in turn is driven and serves to pull the material to be wound up from a supply spool.

The device according to claim 1 wherein said pressure rollers are disposed in opposition relative to each other with respect to said wind-up sPindle.
Claim 8
Dependent Claim
27 words
The device according to claim 1 wherein a compensating roller is disposed between the supply spool and the first pressure roller withdrawing material from the supply spool.
Claim 9
Dependent Claim
34 words
The device according to claim 1 wherein said gearing means is arranged for driving without slippage a pivotally mounted device via a drive belt, said device effecting braking and driving of the supply spool.
Claim 10
Dependent Claim
