    • An arrangement for rolling up and unrolling of material webs, particularly carpets, has a driving drum which is rotatable about its longitudinal axis and is supported displaceably horizontally displaceable in direction toward a rod for receiving an unrolling carpet and extending parallel to the driving drum with adjustable height. The drive of the roll of the carpet arranged on the rod is performed frictionally over the outer surface of the driving drum. By means of a single drive the driving drum is driven in rotation about its longitudinal axis and also applies the pressing force required for the frictional engagement with the carpet roll. For this purpose the drive is connected, on the one hand, directly with a chain wheel which rotates the driving drum about its longitudinal axis, and via a sliding coupling with further chain wheels which engage with stationarily clamped chains and thereby allow a horizontal displacement of the driving drum. The pressing force between the driving drum and the carpet roll is adjusted by the magnitude of the slippage moment of the slipping coupling. During rolling up of the carpet on the above mentioned rod, the driving drum which drives the material web roll of the increasing radius is displaced horizontally with constant pressing force.
