Description
Изобретение относитс к способам соединени листов и пленок из иолихлорвиниловой пластической массы. Оно предусматривает замену сшивани нитками тонких пленок из полихлорвинила точечной сваркой н отличаетс тем, что сварку выполн ют прокалыванием пленок полихлорвинила гор чей металлической иглой.The invention relates to methods of joining sheets and films of iichloro vinyl vinyl plastic. It provides for the replacement of cross-linking of thin PVC films with spot welding and is not characterized in that welding is performed by puncturing PVC films with a hot metal needle.
На фиг. 1 по сн етс подготовка пленок дл сваривани ; на фиг. 2 дана схема приспособленной дл сварки швейной машины.FIG. 1 shows the preparation of films for welding; in fig. 2 is a diagram of a sewing machine adapted for welding.
Перед сваркой кра обеих соедин емых пленок / и 2 снабжают загибами 3. Эти загибы, наложенные друг на друга, подают под лапку 4 швейной машины 5. Размер лапки должен соответствовать размеру загибов 3. Игольница машины имеет несколько игл, например п ть, без нити и снабжена электронагревательной коробкой 7. Иглы б, опуска сь и поднима сь, прокалывают загибы 3 пленок и выход т из них. При вводе игл в пленки пластическа масса расплавл етс и под нажимом лапки заполн ет проделанные иглами отверсти и скрепл ет пленки между собою.Before welding, the edges of both connected films I and 2 are supplied with bends 3. These bends, superimposed on each other, are fed under the foot 4 of the sewing machine 5. The foot size must correspond to the size of the bends 3. The machine needle has several needles, for example, five, without a thread and is equipped with an electric heating box 7. The needles b, down and up, pierce the bends of 3 films and leave them. When the needles are inserted into the films, the plastic mass melts and, under the pressure of the foot, fills the holes made by the needles and holds the films together.
Предмет изобретени Subject invention
Способ соединени листов и пленок из полихлорвиниловой пластической массы методом точечной сварки, отличаюш,ийс тем, что последнюю выполн ют при помощи прокалывани полихлорвинила гор чей металлической иглой.The method of joining sheets and films of polyvinyl chloride plastic mass by the method of spot welding is distinguished by the fact that the latter is performed by piercing polyvinyl chloride with a hot metal needle.
