Description
(54) СПОСОБ ПРЕССОВАНИЯ ВОЛОКНИСТОГО МАТЕРИАЛА(54) METHOD OF PRESSING FIBER MATERIAL
риалом в зону прессовани , образованную двум рабочими поверхност ми - прессовыми валами, которые, враща сь навстречу друг другу, одновременно транспортируют обрабатываемое полотно и подкладной материал , обеспечива их непрерывную подачу в зону прессовани . При этом полотно и подкладной материал сжимаютс между указанными рабочими поверхност ми, только одна из которых контактирует с прессуемым материалом.The rial is in the pressing zone formed by two working surfaces - the pressing rolls, which, rotating towards each other, simultaneously transport the processed web and backing material, ensuring their continuous supply to the pressing zone. In this case, the web and backing material are compressed between said working surfaces, only one of which is in contact with the compression material.
Затем при выходе обрабатываемого материала из зоны прессовани давление снимаетс и происходит его отделение от рабочей поверхности, далее полотно транспортируетс на подкладном материале.Then, when the processed material leaves the pressing zone, the pressure is removed and it is separated from the working surface, then the web is transported on the backing material.
Отделение вышедшего из зоны прессовани , т. е. отпрессованного волокнистого материала от контактирующей с ним рабочей поверхности (от поверхности прессового вала), осуществл ют посредством сообщени ей высокочастотных колебаний.Separating the extruded zone, i.e., the extruded fibrous material from the working surface in contact with it (from the surface of the press roll), is separated by means of high-frequency vibrations.
Полотно силой адгезии удерживаетс на рабочей поверхности - на поверхности прессового вала - и некоторое врем находитс с нею в контакте. Именно в эту зону контакта и подаютс высокочастотные колебани .The web is kept on the working surface by the force of adhesion — on the surface of the press roll — and has been in contact with it for some time. It is in this contact zone that high-frequency oscillations are applied.
Поскольку величина силы отрыва полотна от поверхности прессового вала за счет. подачи высокочастотных колебаний минимальна , полотно при отделении от рабочей поверхности не выт гиваетс и не обрываетс , не наблюдаетс выщипывани с его поверхности отдельных волокон. В результате повышаетс производительность и качество обработку полотна волокнистого материала прессованием.Since the magnitude of the force of separation of the blade from the surface of the pressing shaft due to. the supply of high-frequency oscillations is minimal; the web does not stretch and cuts off when separated from the working surface; no separate fibers are plucked from its surface. As a result, the productivity and quality of processing the web of fibrous material by pressing is improved.
