ABSTRACT:
A device for checking that the base of packets of cigarettes or the like, has been properly sealed down in production lines of the type comprising at least one wrapping machine, at least one overwrapping machine, a conveyor for conveying packets from the wrapping to the overwrapping machine, a memory or retard line for storing signals, working in conjunction with an injection replenishment station for ejecting faulty packets from the production line and for replenishing said production line with products kept in reserve. The checking device is positioned along the conveyor and comprises structure for rendering a faulty base on a wrapped product conspicuous, feeler means for detecting the fault that has been made conspicuous, and structure for restoring the faulty base back in the condition it was originally in prior to being made conspicuous. The feeler sends a signal to the memory system which activates the ejection/replenishment station when the faulty packet reaches such station.
