Summary:The invention relates to a device 1 for feeding foil 2 for the manufacture o f foil bags with at least one supply roll holder 3 that can be driven with a drive, at least one piece of conveyor equipment 4 for conveying a foil 2 from a supply roll 5 th at is held in the supply roll holder 3, at least one foil sensor mechanism 6, which is arranged between the supply roll holder 3 and the conveyor equipment 4, which include s at feast one stationary deflection roll 7 and a first and second dancer roll 8, 9, supported in movable supports 10, 11 for turning the foil 2 around, whereby the foil sensor mechanism 6 for regulating the drive of the supply roll holder 3 is formed depending on the distance from the first and/or second dancer roll 8, 9 to t he deflection roll 7. The invention is distinguished by the fact that the supports 10, 11 of the first and second dancer rolls 8, 9 are hung into at least one flexible hanger 12 that is guided over a deflection wheel 13, 14 and in this way so coupled together that the weight of the first and second dancer rolls 8, 9 is at least partially offset.
