ABSTRACT:
A process for controlling the drive of a reel of a continuous web of material which is fed to a processing machine (packaging machine). The web of material forms a material reservoir upstream of the processing machine. The invention is based on the object to improve this process such that the reel can be driven as continuously as possible for refeeding material into the material reservoir. For this purpose, the filling of the material reservoir is (continuously) determined and the drive of the reel is driven in dependence on the reservoir filling, such that the filling does not fall below a minimum filling and does not exceed a maximum filling. The reservoir filling is preferably determined by comparing the reservoir outflow with the reservoir inflow as well as by a more direct method, preferably by an optical scanning or weighing. The invention further relates to a feed apparatus for conducting this process.
