<p>PURPOSE:To make it possible to glue two kinds of blank webs together by accurately registering them without being deviated from each other by such an arrangement wherein rolls of 2 kinds of blank webs are mounted on shafts which can be controlled by means of a brake, and marks on both rolls are detected while they are being unwound therefrom, and braking force applied to both shafts is properly controlled so that each mark on one roll coincides with a corresponding mark on the other roll. CONSTITUTION:Rolls 1, 2 of 2 kinds of blank webs are mounted on shafts 3, 4 which can be brake controlled respectively, and marks displayed on the blank webs are detected by detectors 14, 15 while rolls 1, 2 are being unwound, and braking force of each of shafts 3, 4 is properly controlled so that marks on both rolls coincide each other. This system can be used for a sealant labeling device, in other words it can be used for such a device wherein a roll of blank web of bag to be fed into a bag making machine can be laid over on a roll of printed matter such as a label and they are glued together.</p> |
