ABSTRACT:
Method and apparatus for forming continuous form sets comprising one or more individual form sheets joined to linearly attached bottom sheets in overlying relationship, the bottom sheets being processed from a continuous web supply and advanced sequentially through a processor with intermittent, unidirectional motion, the individual form sheets being secured to each bottom sheet in synchronism with the bottom sheet motion in aligned, overlying relationship at one or more form set assembly stations, the assembled form sets being folded and collected synchronously with the processing and assembly operations. Individual stock material supplies in the form of continuous length rolls or otherwise are provided in association with each assembly station, there being a stock supply for each individual form sheet in each form set, each form sheet of each set being cut from its own supply and accelerated towards its respective assembly station to enable the intermittent joining of individual form sheets to the bottom sheets while the stock supply is continuously and uninterruptedly fed to the sheet cutter. Suitable perforating, printing, glue line applying, indexing and advancing means are provided.
