Abstract

1426814 Seaming non-metallic sheet material WAVIN BV 7 March 1973 [15 March 1972] 11212/73 Heading B5K In the manufacture of thermoplastic bags, longitudinally spaced transverse seals are made in a tubular thermoplastic film 3 by feeding the film 3 longitudinally in a substantially untensioned condition past a heating member 10 to plasticize the film in zones where the transverse seals are to be formed and passing the film 3, after leaving the member 10, between two pressure rollers 12, 13 to effect sealing. The film 3 is fed from a roll 1 bearing on rotatable rubber rollers 2 by driven rollers 4. Transverse perforations are made by a rotatable drum 5 having projections thereon and cooperating with a backing roller 6. The sealing members 10 are mounted in a metal surface drum 8 and are thermally insulated therefrom. Preferably, each member 10 is made of copper covered with polytetrafluoroethylene. Foam rubber rollers 7, 9 maintain the film 3 in contact with the roller 8 but do not compress it thereagainst. The roller 12 is provided with a cooling spiral 18 and a lever 19 is provided to press the roller 13 against the roller 12. The rollers 4 rotate slightly faster than the rollers 12, 13 so that the film 3 is not tensioned as it passes around the drum 8. A tension roller 20 acted on by a spring 21 draws the film slippingly from between the rollers 12, 13 and then the film passes between rollers 14, 15 driven at the same speed as the rollers 4. Subsequently, the film 3 passes through a printing machine 18a, is doubled longitudinally by a folding triangle 16 and is wound on a device 17.

Description

разм гчаютс  и кажда  нагреваетс  до темпе- , ратуры, достатошой дл  их сварки прессованием . Поверхность валка 7 имеет температуру на бО С ниже температуры разм гчени  пленки .They are softened and each heated to a temperature that is sufficient to be compressed by welding. The surface of the roll 7 has a temperature of C C below the softening temperature of the film.

Прижимные валки 9-11 выполнены из пористой резины. Наименьшее рассто ние меЖ ду поверхностью валка 7 и валками 9-11 соответствуют общей суммарной толщине рукавной пптк . Контактные валки не создают давлени  на рленку.Clamping rolls 9-11 are made of porous rubber. The shortest distance between the surface of the roller 7 and the rollers 9-11 corresponds to the total total thickness of the tubular septum. The contact rolls do not create pressure on the roll.

Далее пленка поступает к Ьхлажденно- у валку, закрепленному на рычаге. Валки 3 и 4 подают пленку быстрее, чем вращаютс  валки 12 и 13. После того, как рукавна  пленка отойдет от сварочного элeкtpoдa 8, в интервале до следующего контакта электрода с пленкой, последн   воздействием нат жного валка 14 и пружины 15 протаскиваетс  сквозь валки 12 и 13. Валки 16 и 17 перемещают рукавную плрнку со скоростью вращени  валков 3 и 4. После этих валков плейка проходит через печатающую машину 18 на складывающее устройство 19, где она сдваиваетс , а затем закручиваетс  в рулон 20.Next, the film goes to the coolant at the roll fixed on the lever. The rolls 3 and 4 feed the film faster than the rolls 12 and 13 rotate. After the tubular film has moved away from the welding electrode 8, in the interval until the next contact of the electrode with the film, the latter is pulled through the rolls 12 and the spring 15 13. The rollers 16 and 17 move the sleeve plate with the speed of rotation of the rolls 3 and 4. After these rolls, the player passes through the printing machine 18 to the folding device 19, where it is doubled and then twisted into a roll 20.

Изобретение позволит осуществить изготовление мещков из тонкой рукавной пленки без ослаблени  ее в ioHe шва.The invention will make it possible to manufacture small cells from a thin tubular film without weakening it in the ioHe seam.
