FORMING ELEMENT FOR FORMING SEALED PACKAGES OF POURABLE FOOD PRODUCTS FROM TUBE OF PACKAGING MATERIAL

摘要

FIELD: machine building.;SUBSTANCE: forming element comprises wall having a first surface to interact with first part of pipe, and two lateral walls extending from wall on its one side and containing appropriate second surfaces to interact with appropriate second parts of pipe, wherein first surface is at least partially concave and has first concave area and second concave area extending from first on side of side walls. First concave area surrounds second concave area. Packing unit for producing sealed packages with fluid food products comprises first and second clamps, cyclically moving between closed state in which they are compressed and sealed pipe and open state in which they are taken aside from pipe, wherein first grip has a forming element described above, and second gripper has additional forming element. Additional forming element contains an additional wall with a third surface for interaction with a third part of pipe, opposite first part, and a pair of additional side walls, protruding at same side of additional wall and containing corresponding fourth surfaces to interact with corresponding fourth pipe parts adjacent to corresponding second parts of pipe.;EFFECT: group of inventions provides higher efficiency and quality.;15 cl, 10 dwg
