A dispensing system has a dispenser for sections of a material web wound onto a roll. More specifically, a mediating server operates to interconnect a number of user devices to destination servers. A determination as to whether to carry out the preparatory process to polishing after completion of the stand-by operation may be made based on the total operating time of the stand-by operation or the total effective number of the stand-by operations. Accordingly, the invention allows for optimization of the energy strain storage capacity of a given elastomer.
