Abstract

Въздушен филтър, състоящ се от лента от филтърен материал с хармоникообразна форма, при която са образувани съседни камери, съединени една с друга по протежение на горния си ръб и залепени по протежение на страничните си ръбове посредством адхезивен материал, характеризиращ се с това, че има форма на паралелепипед, а адхезивният материал е горещ и разтопен. Метод за производство на въздушен филтър, съгласно който адхезивният материал се полага по протежение на ръбовете на лентата от филтърен материал, след което тя се нагъва хармоникообразно, като се образуват съседни камери, характеризиращ се с това, че лентата от филтърен материал първо се деформира по протежение на надлъжни линии на прегъване, при което се образуват издатъци и вдлъбнатини на листа филтърен материал, след което се нанасят две ивици от горещия адхезивен материал по страничните му ръбове, създава се контакт върху плоските зони на листа, последният се нагъва хармоникообразно при намалена скорост на подаване на лентата, по предварително деформираните надлъжни линии на прегъване, като нагънатата лента се поддържа компактна в продължение на определено време, при което горещият адхезивен материал напълно изсъхва, след което нагънатата хармоникообразно лента се нарязва на части, съдържащи определен брой камери, като към горната страна на тези части се поставя съответен материал, който се втвърдява и образува херметизиращ уплътнител за горния периферен ръб на въздушния филтър. Машина за осъществяване на метода, включваща ролка, върху която е навито руло с лента от филтърен материал, и устройство за хармоникообразно нагъване на лентата, характеризираща се с това, че след ролката, върху която е навито рулото с лента от филтърен материал, са установени последователно контролно устройство, устройство за деформиране на лентата, устройство за полагане на горещия адхезивен материал върху ръбовете на лентата, подаващо устройство, устройство за хармоникообразно нагъване на лентата и отвеждащото устройство за нагънAn air filter consisting of a band of filter material having an accordion shape in which adjacent chambers are formed, joined together along their top edge and bonded along their side edges by means of an adhesive material characterized by having parallelepiped shape, and the adhesive material is hot and molten. A method of manufacturing an air filter in which the adhesive material is applied along the edges of the strip of filter material, then folded harmonically to form adjacent chambers, characterized in that the strip of filter material is first deformed along along longitudinal fold lines, in which protrusions and depressions are formed on the sheet of filter material, then two strips of the hot adhesive material are applied along its side edges, contact is made on the flat areas of the sheet, the latter is folded harmonically at a reduced speed of feeding the tape, along the pre-deformed longitudinal fold lines, keeping the crimped tape compact for a certain time, during which the hot adhesive material is completely dry, after which the crimped accordion-shaped tape is cut into parts containing a certain number of chambers, as to a suitable material is placed on the upper side of these parts, which hardens and forms a sealing gasket for the upper peripheral edge of the air filter. A machine for carrying out the method, including a roll on which a roll of filter material tape is wound, and a device for harmonically crimping the tape, characterized in that after the roll on which the roll of filter material tape is wound, sequential control device, strip deformation device, device for placing the hot adhesive material on the edges of the strip, feeding device, harmonic strip crimping device, and crimp removal device
