ABSTRACT:
A method of manufacturing a selective isolation screen includes steps of preparing for a tubular screen provided with spacer members and a wire on a base member, and supplying sealing material from a sealing material supply device which supplies sealing material at a location where sealing is required on the tubular screen while rotating the sealing material supply device relative to the tubular screen thereby filling the annulus between the spacer members which are adjacent to each other in the circumferential direction to form seal means. Difficulty in welding can thereby be avoided and location and state of mounting of sleeves can be visually checked.
