DEVICE AND METHOD FOR MANUFACTURING PACKAGES WITH WELDED SEAM ALONG PERIMETER Russian patent published in 2021 - IPC B65D75/54 B65D75/30 B32B37/14 

FIELD: packaging.

SUBSTANCE: invention relates to a method for manufacturing a package with a welded seam along the perimeter with layered composite placed in it, to a device for manufacturing a package with a welded seam along the perimeter using the specified method, as well as to a package with a welded seam along the perimeter manufactured by the specified method. A method for manufacturing package (160) with a welded seam along the perimeter with layered composite (141) placed in it, device (10) for manufacturing packages with a welded seam along the perimeter using the specified method, as well as package (160) manufactured by the specified method are claimed. Layered composite is separated from web (140) consisting of layered composites, which includes film substrate (110) with substrates (130) placed on it, which are respectively covered with covering film (136). Intermediate body (165) is brought to the web of layered composites or to layered composite, or intermediate body (165) is formed in film substrate, wherein intermediate bodies(y) at least locally surround(s) all free substrate surfaces (133). Layered composite (141) and all intermediate bodies are inserted between two webs (61, 62) of packaging material. Webs of packaging material are welded to each other. Finally, packages (160) with a welded seam along the perimeter are separated.

EFFECT: specified method and device are developed for the automated manufacture of packages with a welded seam along the perimeter described in the claim.
