Splice Detector
Industrial filling processes for beverage containers made from cardboard sandwich often use polyethylen tapes for sealing at the welded seams. The 5 to 50 μm thick and 10 km long tapes are furled on spools. As the tapes can not be extruded in one piece of this length, 
they are spliced together from shorter runs. These splices are problematic for the filling process, since they could cause leakages or process interruptions.
Our system quickly and reliably detects the splices within the tapes so that affected beverage containers can be dropped in time during the filling process. This increases the process stability and the product quality (reduced leakage risk, increased shelf life).
The splice detector uses a robust capacitive sensor principle and can easily be adjusted to different tape widths and thicknesses. The data interface is compatible with industrial automation bus systems.
