A supply device for a tire-building drum, in particular for a tire-belt drum for building a multilayer tire-belt package for a pneumatic tire, where a plurality of layers of different or differently treated, substantially strip-like pieces of material web are, in succession, placed on, rolled onto, and bonded to one another on the tire-building drum. The supply device has cutting devices in which cut-to-length pieces of material web are formed and then transported to the tire-building drum by a drum supply device, which has two drum feed belts. Two pairs of cutting devices are disposed mutually above one another and assigned to the drum feed belts. The cutting devices are displaceable relative to the drum feed belts such that, in the backward receptive position, the drum feed belts can be brought into active contact in alternation with one of the pairs of cutting devices. The pairs of cutting devices are coupled to advancer belts that are equally arranged in pairs and, together with the cutting devices, can be positioned individually in front of the drum feed belts. The advancer belts and the drum feed belts are laterally moveable with respect to one another.
