METHOD AND DEVICE FOR MANUFACTURING SEPARATION MEMBRANE ELEMENT

To provide a method for manufacturing a separation membrane element which does not cause a sealing failure due to an adhesive filling failure to a step part of a separation membrane unit tip near a water collecting pipe.SOLUTION: In winding a laminate 11 around a water collecting pipe 5, the occurrence of a leakage defective due to a sealing failure of an adhesive near the water collecting pipe, a poor winding form and a winding diameter failure due to a wrinkle, and a deterioration in filtration performance are avoided, and the adhesive is prevented from being adhered to the device by applying movement resistance only to a lower side surface of the laminate 11 on a guide plate 62 of the laminate 11 at a relatively close position of a distance within 50% from the water collecting pipe 5 with respect to a width dimension of a permeation side flow passage material 4b, giving or magnifying tensile force to the permeation side flow passage material located at the bottom layer of the laminate with the water collecting pipe 5 joined to a tip when wound around the water collecting pipe 5, and by holding pressing force during winding.SELECTED DRAWING: Figure 5 【課題】集水管近傍の分離膜ユニット先端の段差部への接着剤充填不良による、シール不良を生じることない分離膜エレメントの製造方法を提供する。【解決手段】積層体１１を集水管５に巻付ける際に、積層体１１の案内板６２上で、集水管５から、透過側流路材の幅寸法に対し、５０％以内の距離の比較的近傍な位置で積層体１１下側面のみに移動抵抗を付与し、積層体最下層に位置し、集水管５と先端部が接合された透過側流路材４ｂに対し、集水管５への巻き付け時に張力を付与または増幅させ、かつ、巻き付け中にその押圧力を保持することで、集水管近傍の接着剤のシール不良によるリーク不良品の発生および、シワによる巻き形態不良や巻き径不良、濾過性能悪化を回避し、装置への接着剤付着を回避する構成とする。【選択図】図５
