METHOD OF PRODUCING WORKPIECE FROM PACKING LAMINATE, WORKIPIECE THUS PRODUCED AND PACKING CONTAINER

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to fabrication of workpiece from thermally sealed and foldable laminate for packing container resisting SHF heating. Endless ribbon (1) of starting laminate (10) moves in packing laminate conversion line. Endless workpieces for aforesaid packing containers are directed from top to bottom and across machine processing direction in conversion line and top-to-bottom interface (51). Starting laminate (10) is made with bents and cuts for workpieces (50a, 50b). Endless ribbon (2) from heat and electrically conducting material is applied along machine processing direction above aforesaid interface (51) and in combination with stage (a). Elongated indication (53) of hole is effected prior to or after applying ribbon (2). Hole indicator stays within the limits of aforesaid ribbon. Packing container is formed by folding, is filled and sealed by workpiece (50a, 50b). ^ EFFECT: higher density, reliability and tightness. ^ 23 cl, 8 dwg
