Method and device for separating a wrapping web of double width into two partial webs

摘要

The device for separating a commencement casing material into two part strips for fed to a twin strip cigarette processing machine, uses a longitudinal rotary cutting device. Two measuring units (26,27) monitor the width of the part strips (3,4) and a positioning component (29) undertakes a relative adjustment between the commencement casing material strip (1) and the longitudinal cutting device (6). A control unit (28) is brought into contact with the center line of the longitudinal cutting devicec dependent upon width deviations of the part strips andn is in effective connection with the width measurement units.
