Abstract: A method and corresponding system for assembling collation sets from a split web consisting of two webstreams, each providing a series of collations of connected sheets. The method includes the steps of: alternately selecting the two webstreams and from the selected webstream drawing a sheet to a cutting or bursting station; cutting or bursting the sheet to separate it from the webstream; conveying the sheet to an accumulating station where sheets are accumulated; monitoring the sheet for determining whether the sheet is a beginning or an end of a collation; and ejecting the sheets accumulated from the selected webstream based on the determining of whether the sheet is the beginning or the end of a collation.
