ABSTRACT:
An infeed station comprises an eccentric roller fitted between two rotary plate around which a web-like sheet travels so as to have the sheet's speed transform from a constant inlet speed into a varying outlet speed according to the preconditions of the travel of the sheet in an operating cycle of the working station. The infeed station includes an infeed roller which guides the web-like sheet from the eccentric roller toward the working station, and this infeed roller is driven by an independent drive arrangement so that the peripheral speed follows the conditions similar to the outlet speed of the web-like sheet although remaining permanently at a higher rate.
