れた紗を剥がす必要があるが、多くの枠体は無機質な材
質から成るために、ボンド（商品名）などの接着力の高
い接着剤を用いており、印刷終了後に紗を剥がすことが
困難である。That is, as described above, it is necessary to peel off the gauze once adhered to the frame, but since many frames are made of an inorganic material, high adhesion such as a bond (trade name) is required. It is difficult to remove the gauze after printing is completed because of the use of an agent.

After the base adjustment treatment, air drying is performed (Claim 2). Preferably, the adhesive is composed of a hot melt adhesive and a diluent, and the mixing ratio of the hot melt adhesive to the hot melt adhesive 1 is adjusted. Using a diluent of 0.3 to 0.5, the adhesive is spray-coated on the surface of the frame at a pressure of 1 to 2 kg / cm 2 to form a coating film having a thickness of 1 to 3 mm.

慮して、上記圧力により行う。As the adhesive 30, a solution-type hot-melt adhesive containing methylene chloride (methylene chloride) as a main component is used. Adhesive 30 is obtained by mixing a diluent consisting of 0.3 to 0.5 or a hot melt adhesive with a diluent consisting of a solution type polyester thinner at a ratio of 50:50 to 70:30. A gun is blown at a pressure of 1 to 2 kg / cm 2 by an air compressor so as to uniformly apply the film to the frame surface 20 and not to exceed the boiling point of the adhesive. Here, when the adhesive 30 is blown by a gun with an air compressor, the temperature of the adhesive 30 rises depending on the air pressure due to the relatively low boiling point of the adhesive 30, causing the air to be sprayed, and It cannot be uniformly applied to the body surface 20. In order to form a coating film having a certain thickness on the frame body surface 20 by uniform coating, the above pressure is used in consideration of the composition of the adhesive 30.

な使用回数を得ることができない。In order to allow the frame frame to be reused about 100 times, the gauze is peeled off from the frame body 10 after printing is completed, and the frame body 10 is again stretched by the heating and pressing step described later. The thickness of the coating film is a natural drying process,
After the baking process described later, the thickness is set to 1 to 3 mm, preferably about 2 mm. Below this, the adhesive strength decreases with the number of uses, and a sufficient number of uses cannot be obtained.

After a natural drying process for about 10 hours or more, the adhesive 30 is baked on the frame surface 20 by heating at 110 to 130 ° C. for 30 to 50 minutes in a gas furnace or an electric furnace.
Thereby, even in the replacement of the gauze that the gauze is peeled off from the frame 10 to be described later and the gauze is again applied to the frame 10,
The frame 10 can be reused without the adhesive 30 peeling off from the frame surface 20.

て接着剤が架橋固化して紗が枠体に張着される。The material of the gauze generally used for screen printing is silk, nylon, polyester, tetron, etc., whose melting point is higher than the melting point of the adhesive 30, and therefore gauze applied to the frame 10. When pressed by the heating and pressing means 60 from the upper surface of the frame 40, the adhesive 30 on the frame body surface 20 is partially melted, and the mesh of the gauze 40 is slightly buried in the melted portion. Is dried and solidified, the adhesive is cross-linked and solidified via the adhesive on the frame and the gauze, and the gauze is adhered to the frame.

において押圧し、圧着させることが好ましい。Therefore, as shown in FIG. 3, the gauze 40 adhered to the frame 10 exhibits a strong peel strength in the extending direction, but the cross-linking in the non-extending direction, that is, the vertical direction. It is weak due to the action of the part, and the gauze 40 can be easily peeled off from the frame body 10 in the gauze refitting work described later. However, when the gauze 40 is bonded to the frame body 10, the gauze 40 is adhered over the entire surface of the frame body surface 20. Let's make it 40
Since it is not preferable in consideration of peeling off, the heating and pressing means which is partially heated and pressed on the outer periphery of the frame to the extent that the gauze 40 adheres to the frame 10, for example, a known temperature adjusting mechanism and a heat generating mechanism shown in FIG. It is preferable to press and crimp the electric iron 60 having it by a manual operation or an automatic machine.
