  • Publication number: 20130244852
    Abstract: A method for a continuous production of filters, particularly coffee filters and the like, from a material web, including the steps of (a) cutting parallel in reference to the direction of transportation of the material web to separate at least two rows of filter contours extending parallel in reference to the direction of transportation of the material web into one partial material web each, and (b) separating the filters of the respective partial material webs. The cutting to separate at least two rows into one partial material web each occurs essentially based on a cut with a wave-like progression. At least two partial material webs are arranged over top of each other such that a separation of the filters of the respective partial material webs occurs by a joint cut. A device for a continuous production of filters is also provided.
