ABSTRACT:
In the packaging of articles, especially brittle articles, such as biscuits or the like, a test must be carried out to ensure that the pack content is complete and intact. For this purpose, each pack (10) is tested, during its continuous conveyance via conveying means (17 to 20), by means of at least one mechanical feeler (21) taken along with it in the conveying direction. This feeler (21) is pressed onto the soft pack with a specific force by means of its feeler plunger (22) via a spring (26). A fault in the pack content is revealed when the feeler plunger (22) comes to rest outside a specific region monitored by light barriers (33) which check the position of an end portion of the feeler (21).
