无纺布制袋机是由给料机实期送粉料(胶体或液体)到包装机上方的料斗器内，引进速度由光电定位装置控制，成卷的封口纸(或其它包装材料)经导辊带动引进至翻领成型器，被折弯后再由纵封器搭接成为圆筒状，物料被自动计量后充填到制成的袋内，横封器在进行热封切割的同时将袋筒间歇地向下牵引，最后形成搭接纵缝三面封口扁平袋，完成一个袋的封口。
The non-woven bag making machine is a hopper which feeds powder (colloid or liquid) to the top of the packing machine in real time. The speed of introduction is controlled by photoelectric positioning device. The rolled sealing paper (or other packing material) is driven by the guide roll and introduced into the lapel shaper. After being bended, it is lapped by the longitudinal sealing device to form a cylinder. The material is automatically measured and filled into the bag. The horizontal sealing device is heated. At the same time, the bag cartridge is pulled downward intermittently. Finally, a flat bag with three overlapping longitudinal seams is formed to seal a bag.
