In one embodiment, the welding module 100 according to the present invention may further include folding means 110, cutting means 120 and bonding means 130.

The folding means 110 forms a leaf element by interposing a supply spacer 2 between the incoming reverse osmosis membrane 1 and automatically or semi-automatically folding the reverse osmosis membrane 1 together with the supply spacers 2. At this time, the folding unit 110 can be folded by the hinge unit 111, thereby performing the function of folding the reverse osmosis membrane 1 located above the reverse osmosis membrane 1 with the supply spacers 2 interposed therebetween.

The adhesive application module 200 may be configured to apply an adhesive to at least one adhesive application area.

At this time, the adhesive application module 200 is similar to the method of applying the adhesive to the reverse osmosis membrane 1 or the supply spacers 2 when manufacturing the leaf elements 1 and 2 described above. That is, an adhesive is applied to the edges and cut portions of any one of the leaf elements 1 and 2 and the tricot filtration water path 3 to apply the leaf elements 1 and 2 and the tricot filtrate water (3) can be adhered. Here, the portion to be cut may mean the leaf element 1, 2 and the tricot filtrate water portion 3 corresponding to the portion to be cut by the cutting module 500, which will be described later.

The trimming means 42 cuts each of the reverse osmosis filter modules 10 to an appropriate length and then covers both ends with a protective member. However, the description thereof is omitted since it is a known technique.

The reverse osmotic pressure filter module of the conventional reverse osmosis filter module manufacturing apparatus can produce the leaf element by using the slitted reverse osmosis membrane after the width of the reverse osmosis membrane is slitted to the length of the reverse osmosis filter module in the future. However, when the width of the reverse osmosis membrane is preliminarily cut by the slitting process, the reverse osmosis membrane is cut in accordance with the length of the reverse osmosis filter module in advance, resulting in an unused area, resulting in economical loss.

However, the reverse osmotic pressure filter module 10 of the reverse osmotic pressure filter module manufacturing apparatus according to the present invention uses the reverse osmosis membrane 1 not subjected to the slitting process to manufacture the leaf elements 1 and 2, 2 and tricot filtered water 3 are wound on the tube 4 and then cut to the length of the reverse osmosis filter module 10 to remove unused leaf elements 1 and 2 and tricot filtered water 3 ) The area is not generated, and economic effect may occur.
