Claims (5)

1. Устройство для индукционной сварки упаковочного материала, покрытого слоем термопласта, включающего в себя по меньшей мере один слой металлической фольги, предпочтительно алюминиевой фольги ("Аlifoil"), причем устройство содержит индуктор, подсоединенный к источнику высокочастотного тока и имеющий по меньшей мере два параллельных, слегка разнесенных друг от друга проводника и электрически изолированную часть держателя, отличающееся тем, что оба проводника соединены друг с другом и с источником тока посредством поперечных проводников, размещенных в верхней поверхности индуктора таким образом, что они совпадают с наружными определяющими линиями упаковочного материала.1. A device for the induction welding of packaging material coated with a layer of thermoplastic comprising at least one layer of a metal foil, preferably aluminum foil ("Alifoil"), the device comprising an inductor connected to a high-frequency current source and having at least two parallel , slightly spaced apart conductor and an electrically insulated part of the holder, characterized in that both conductors are connected to each other and to the current source through transverse conductors, p located in the upper surface of the inductor in such a way that they coincide with the outer defining lines of the packaging material. 2. Устройство по п. 1, отличающееся тем, что наружные определяющие линии упаковочного материала совпадают с центральной линией поперечных проводников с допуском ± 1,5 мм. 2. The device according to claim 1, characterized in that the outer defining lines of the packaging material coincide with the center line of the transverse conductors with a tolerance of ± 1.5 mm. 3. Устройство по п. 1, отличающееся тем, что ширина и глубина поперечных проводников такие, что потребляемая выходная мощность для сварки кромочной зоны упаковочного материала равна потребляемой выходной мощности для сварки центральной зоны упаковочного материала. 3. The device according to claim 1, characterized in that the width and depth of the transverse conductors are such that the consumed output power for welding the edge zone of the packaging material is equal to the consumed output power for welding the central zone of the packaging material. 4. Способ индукционной сварки упаковочного материала, содержащего по меньшей мере один слой термопласта и слой металлической фольги, предпочтительно алюминиевой фольги, расположенный смежно с ним, причем сварку осуществляют посредством устройства, так называемого индуктора, имеющего два параллельных проводника, соединенных друг с другом и с источником высокочастотного тока, посредством которого наводят электрический ток высокой частоты в слое металлической фольги упаковочного материала, из которого тепло, образованное током, передается слою термопласта для его расплавления, при этом взаимно соединенные и спрессованные слои упаковочного материала связывают друг с другом за счет оплавления взаимно обращенных слоев термопласта и образуют непроницаемое и прочное сварное соединение, отличающееся тем, что поперечные проводники размещают в верхней поверхности индуктора так, что они совпадают с наружными определяющими линиями упаковочного материала, и тем, что поперечные проводники проводят ток между двумя главными проводниками. 4. The method of induction welding of packaging material containing at least one layer of thermoplastic and a layer of metal foil, preferably aluminum foil, located adjacent to it, and welding is carried out by means of a device, the so-called inductor, having two parallel conductors connected to each other and to a high-frequency current source by means of which a high-frequency electric current is induced in a layer of metal foil of the packaging material, from which heat generated by the current is transmitted They are molded by a thermoplastic layer to melt it, while the mutually connected and compressed layers of packaging material are bonded to each other due to the fusion of the mutually reversed layers of the thermoplastic and form an impermeable and durable welded joint, characterized in that the transverse conductors are placed in the upper surface of the inductor so that they coincide with the outer defining lines of the packaging material, and the fact that the transverse conductors conduct current between the two main conductors. 5. Способ по п. 4, отличающийся тем, что сварку осуществляют по прямоугольной схеме, где короткие стороны прямоугольника состоят из наружных определяющих линий упаковочного материала. 5. The method according to p. 4, characterized in that the welding is carried out according to a rectangular pattern, where the short sides of the rectangle consist of the outer defining lines of the packaging material.
