Title: Process and apparatus for the manufacture of a relief printing form
Inventor: SCHOUTE JOHANNES CORNELIS
IPC: G03F7/18
Filed: 1979-06-27
Granted: 1983-02-03
Abstract: A process is provided for making a relief printing form which is at least partially cylindrical from a liquid photopolymerizable molding material. In accordance with the process, a molding material is spread over the internal surface of the cylindrical wall by centrifugal force and hardened in the desired places with ultraviolet light to form an image corresponding to a printing design. The nonhardened portions of the molding material are then removed. The cylindrical wall is a transparent cylindrical tube. An exchangeable image-bearing film is placed on the inside of the tube. Photopolymerizing radiation of the printing form material is effected during rotation of the transparent cylindrial tube. An exchangeable image-bearing film is placed on the inside of the tube. Photopolymerizing radiation of the printing form material is effected during rotation of the transparent cylinder by means of one or more radiation sources distributed around the circumference of the transparent cylinder. The rays act on the molding material via the wall of the transparent cylinder and the image-bearing film. The radiation for hardening the printing form takes place in a continuous operation following the application of the molding material to the cylindrical wall by centrifugal force.

Title: Method for packing tubular bags in boxes, and device for carrying out the method
Inventor: BENZ GOTLIEB
IPC: B65B35/50
Filed: 1983-11-23
Granted: 1987-02-05
Abstract: The present invention is directed to a method and apparatus for packing tubular bags into boxes by machinery. The tubular bags to be packed are conveyed over various conveyor belts to a positioning belt and from the positioning belt to a positioning table. Layers of tubular bags are then moved onto a rake-like main base that is lowered in a stepwise fashion to receive consecutive layers of tubular bags. When the desired number of tubular bag layers is positioned on the main base, the main base is lowered to deposit the tubular bags onto an intermediate base which together with side walls makes up an intermediate container. Once the intermediate container is in a lower position, a box is pushed over the intermediate container and the intermediate container is swung through a 90 DEG arc onto a conveyor belt. The intermediate container is then removed from the box and by this process the tubular bags which were previously in the intermediate container are transferred into the box. The intermediate container then swings back to its lower position.
