İKİ KATLI BİRLEŞTİRME İŞLEMİNİN ANA KARAKTERİSTİKLERİNE ISI İLE BİRLEŞTİRME İŞLEMİNİN ETKİSİ ÜZERİNE BİR ARAŞTIRMA

In the manufacturing process, the heat-sealed treatment is an important step, because it contributes to the shape of the product and to dimensional stability during its use. In the heat- sealed treatment it is important to choose the proper values of pressure and temperature, correlated with the time needed for each phase, because the adhesive temperature increases as the surface temperature of the base material rises. This paper presents some results concerning the correlation between the heat- sealed parameters and some characteristics of a doubled ensemble (the detachment capacity, wrinkling recurrence and rigidity) by taking into account the direction by which the adhesive material is attached to the base one
