Method and device for connecting two ends (304, 309) of foil (8-12, 106, 308) by means of tape (250). Foil (8-12, 106, 308) is supplied and processed, e.g. buffered. One or more tape applicators (103, 104) are configured for applying tape (250) to and connecting the ends of foil (304, 309). The tape applicator (103, 104) comprises a tape receiving surface (153, 154) having one or more tape holders arranged to, when switched on, fix the position of the tape (250) on the tape receiving surface (153, 154). A tape dispenser (93) is arranged to supply tape (250) onto the tape receiving surface (153, 154). The tape (250) is dispensed to a remote part of the tape receiving surface (153, 154) and a blower blows the tape (250) onto the tape receiving surface (153, 154) while being dispensed.

摘要:
A method of splicing laminated films, comprising the steps of splicing extended base film layers (3, 4) to each other in a principal rafter shape at a connection part between the rear end portion and top end portion of the laminated films (1, 2) having the extended base film layers (3, 4) and sealant layers (5, 6) to make the interconnected part of the laminated films sufficiently contribute to the manufacture of a packaging bag and provide excellent airtightness and sealability to the connection part itself, and providing a tensile strength necessary for the laminated films to the connection part to eliminate the need of temporary stop of a packaging device when the connection part of the laminated films passes the packaging device so as to increase a working capability and a working efficiency and also increase the yielding of material.
摘要:
The invention relates to a method for joining an initial section (3) of a strip-type tubular film (2) to an end section (4) of a second tubular film (5) extending in an at least partially strip-type manner over successive processing stations, especially a packing installation. According to said method, the strip-type initial and end sections (3, 4) respectively have two superimposed outer lateral surfaces (10, 11, 15, 16) that respectively turn into two inner, inwardly folded, lateral surfaces (17, 18, 19, 20) in the edge regions thereof, said lateral surfaces forming an inner folding axis (S, T). According to the invention, a tongue (7, 27) is formed by cutting the two outer edge regions of the initial or end sections (3, 4), said tongue being connected to the opposite section (3, 4) in a tensile-proof manner. The initial section (3) overlaps the end section (4).

Um die Enden von flachliegenden und mit Seitenfalten (2) versehenen Schlauchfolienbahnen (1,8) aus thermoplastischem Kunststoff in der Weise miteinander durch eine Querschweißnaht (10) zu verbinden, daß die Innenfalten von außen her auch im Verbindungsbereich durchgängig bleiben, wird ein Ende mit die Innenkanten der Seitenfalten auftrennenden Schnitten versehen. Das andere Ende wird in den aufgeschnittenen Bereich in der Weise eingeschoben oder eingelegt, daß die beiden Wände mit je einer Lage (4,6) jeder Seitenfalte des Endbereichs der einen Schlauchfolie (1) das andere Ende zwischen sich einfassen. In die Seitenfalten des eingefaßten anderen Endbereichs werden Trennschichten (9) eingeschoben oder eingelegt und die Enden werden sodann durch eine Querschweißnaht (10) miteinander verbunden.
摘要:
A coupled portion of mutual laminate films sufficiently contributes to the formation of a packaging bag, and the coupled portion itself has excellent airtightness and liquid tightness, and a tensile strength required for the laminate film is given to the coupled portion, whereby a temporary stop of a packaging apparatus is useless when a connecting portion of the laminate film is passed through the apparatus and the operation efficiency and efficiency are enhanced and the yield of the material is improved, wherein oriented base film layers (3, 4) are joined in a mitre form at the coupled portion between a rear end portion and a front end portion of laminate films (1, 2) comprising oriented base film layers (3, 4) and sealant layers (5, 6).
摘要:
Device (1) and method for connecting two ends of foil (304,309) by means of adhesive tape (250, 270). A continuous foil (106, 308) is obtained by connecting the end (304) of already supplied foil (106) to a new beginning (309) of a further foil (308) at a second position. The end of the old foil (304) is formed at a first position. The device (1) comprises foil supplies (2-6) supplying foil (8-12, 106, 304). A carriage sub frame (101) is mounted movably on a frame between at least the first position and can be guided towards the second position. The carriage sub frame (101) supports at least a foil end holding unit arranged for holding an end of the foil (304, 308) supplied from the foil supply (2-6). The device (1) further comprises a connection unit for connecting the ends of foil (304, 308), and a tape dispenser (120) for dispensing tape (250) to connect the foil ends. The tape dispenser (120) is mounted on the carriage sub frame (101).
摘要:
A method for butt joining a band of flexible material, heat-sealing on at least one side and pre-printed on the opposite side, the band being unwound from a parent reel, cut longitudinally into strips and rewound into reels or rolls, the method consisting in overlaying the tail edge (L1) of a finished parent reel on top of the leading edge (L2) of a new parent reel, so that the printing of the one coincides with that of the other, cutting the band transversely along a line in the area of overlaying of the edges (L1, L2), removing the ends trimmed from the edges (L1, L2) and heat sealing on the heat-sealing side of the band, along said cutting line, a strip of heat-sealing material (S).
