Abstract
The present invention relates to an apparatus for supplying foil material, the apparatus comprising a motor-driven supply roll, a withdrawal means and a consumption sensor provided between the supply roll and the withdrawal means for controlling the drive of the supply roll in response to the consumption of foil material, and at least one stationary deflection roller, at least one sensor roller and a sensor means, the sensor roller being supported and arranged such that it changes the distance from the stationary deflection roller in response to the difference between supply capacity and withdrawal capacity of the foil material, and the sensor means senses said change in distance and accelerates the supply roll when the distance is smaller than a first predetermined distance, and slows down the supply roll when a second predetermined distance is exceeded. Furthermore, the invention relates to a corresponding method for supplying foil material.
