A fold type filter and a method for manufacturing the same

The invention provides a method for manufacturing a fold type filter. The method comprises the steps of soaking non-woven cloth or glass fiber non-woven cloth manufactured at high temperature or normal temperature in a heat-resisting resin water solution for dipping processing; taking the non-woven cloth or glass fiber non-woven cloth out and drying the non-woven cloth or glass fiber non-woven cloth at low temperature; folding the non-woven cloth or glass fiber non-woven cloth and then solidifying the same; winding a shape-maintaining band around and combining the shape-maintaining band to the periphery of the solidified folded non-woven cloth, namely the fold type filter bag; driving in U-shaped nails from the outside to fix the shape-maintaining band, wherein the shape-maintaining band is an annular band in the length direction and the inner side surface thereof is coated with adhesive. 本发明的褶式过滤器的制造方法，包括：将高温或常温下制成的无纺布或玻璃纤维无纺布浸入耐热性树脂水溶液中进行浸渍加工，将其取出后低温干燥，再将其折叠后进行固化；以及在被固化的折叠无纺布即褶式滤袋上沿着其外周缠绕结合保形带，并从外部钉入U形钉来固定保
