Polybag Seal Detection

To locate the perforations between plastic bags on a web

Description

Plastic bags are manufactured in a continuous web, with a seal and perforation between bags. To ensure the bag is properly separated from the web, a D10 Expert signals the location of the perforation to the separation mechanism, based on the location of the seal; in effect the seal acts as a registration mark. The low-contrast capability of the D10 Expert and the light-averaging ability of the PIL46U fibers combine to reliably sense the bag seal.
