Title: Uwe Kohn: Innovator in Packaging Technology
Introduction
Uwe Kohn is a notable inventor based in Osnabruck, Germany. He has made significant contributions to the field of packaging technology, holding a total of 11 patents. His innovative designs have improved the efficiency and functionality of packaging systems.
Latest Patents
One of Uwe Kohn's latest patents is a bag-in-bag packaging system. This system features an inner bag made of two layers of polyethylene, which is surrounded by an outer bag consisting of three layers of polyethylene. Each bag is designed with a closed bottom and an open top prior to filling. After the inner bag is filled, it is sealed with a first heat seal, which can be performed through the outer bag without sealing the two bags together at that point. The outer bag is then closed with a second seal, located between the first seal and the top of the bag. A frangible zone is positioned between the first and second heat seals, allowing the outer bag to be removed from the sealed inner bag by cutting or tearing along this zone.
Another significant invention is a device for eliminating defective flat objects and forming stacks of flawless items. This device is designed to eliminate defective flat objects, such as tubular segments or sack workpieces, during the production of sacks. It features a twin belt conveyor that conveys the objects individually and at a distance from each other. The system includes a scanning mechanism to identify defective objects and a shunt that eliminates these objects. Additionally, the device has a stack shaft with an intermediate stacker plate to organize the flawless objects.
