Description

Manufacturing method of laminated mat

The present invention relates to a manufacturing method of a laminated mat used in cushions, car seats, pillows and the like.

In general, the mat is woven into the shape of a royal fabric and is manufactured in the form of a wide plate, and then used for the production of seats, cushions, or seats for vehicles. When making these products with only mats, there is no cushion at all. There was a problem that was uncomfortable to sit down for a long time.

Due to such a problem, a laminated mat made of a mat-sponge-lyrex is newly proposed by attaching a sponge and a relex to the bottom of the mat.

The conventional method of manufacturing a laminated mat is a process of attaching a mat and a sponge by applying an adhesive to the bottom surface and spreading the sponge on the bottom surface in a state where the bottom surface of the mat faces upward, and then pressing It consists of a Relex attachment process that applies adhesive to the surface of the furnace sponge, spreads Relex on it, and presses it to attach Relex.

Since the conventional method for manufacturing a laminated mat is manufactured by attaching a mat of a certain size, a sponge, and a Lyrex sequentially using an adhesive, a uniform adhesion cannot be made and a problem arises that the adhesive part is pushed or lifted during use. And, it takes a lot of time to apply and pressurize the adhesive, there is a problem that the productivity is very low because the manufacturing of the laminated mat is produced by being divided into each step.

The present invention is to heat-sealed in the process of passing through the pressure roller and Relex-sponge after manufacturing the Relex-sponge laminated body in the form of a roll, and in the process of passing the mat supplied through a separate line through the pressure roller By presenting a new method for manufacturing a Lyrex-sponge mat laminate by heat-sealing with a Lyrex-sponge laminate, it is possible to continuously manufacture a laminated mat, which greatly shortens the manufacturing process and improves manufacturing efficiency. It is designed to increase the durability of the mat, sponge, and Lyrex by attaching them in an integrated state by heat.

The present invention comprises a Relex-sponge laminate manufacturing process and a Relex-sponge-mat laminate manufacturing process.

In the Lyrex-sponge laminate manufacturing process, the roll-shaped sponge 1 and the Lyrex 2 are supplied to the pressure rollers 3a and 3b through separate supply lines, but uniform heat is applied to one surface of the sponge. The sponge and Lyrex are heat-sealed by passing between the pressure rollers in the applied state, and the manufacturing process of the Lyrex-sponge-matte laminate (6) is in the form of a roll-like Lyrex-sponge laminate (4). The mat 5 in the folded state is supplied to the pressure rollers 3a and 3b through separate lines, but is pressurized with uniform heat applied to the surface of the sponge 1 of the Lyrex sponge laminate 4. Passing between the rollers has a configuration such that the Lyrex sponge laminate 4 and the mat 5 are heat-sealed.

In the above, the sponge 1 has a property of melting by heat, and the melting portion exerts a strong adhesive force, and thus the surface portion becomes molten at the moment of contact with the flame of the burner 7.

In this state, when contacted with Lyrex, it is adhered with Lyrex with strong adhesive force, and the supply of Lyrex and sponge, operation of burner and operation of pressurized roller are continuously made by a mechanical device. The Lyrex-sponge laminate 4 is subsequently produced.

After the manufacture of the Lyrex sponge laminate is finished, the Lyrex sponge laminate 4 is passed between the pressure rollers 3a and 3b so that the sponge side is exposed to the flame of the burner, and the mat 5 is By passing through a separate supply line and passing through a pressure roller, a sponge and a mat in a molten state are attached to each other to prepare a Relex-sponge-mat laminate 6.

Fig. 1 shows a Relex-sponge laminate manufacturing process according to the present invention, in which the sponge 1 is exposed to the flame of the burner 7 before passing the pressurization portion of the pressure rollers 3a and 3b. It is seen that the Relex (2) supplied through a separate line and the pressurizing portion of the pressure roller, the Relex and the sponge is attached in the process of passing through the pressure roller.

The cross-sectional structure manufactured by the Lyrex-sponge laminate manufacturing process has a cross-sectional structure in which Lyrex is attached to and integrated with one surface of the sponge as shown in a.

Figure 2 illustrates a process for producing a Rex-Sponge-Cart mat laminate according to the present invention, the sponge surface of the Reex-Sponge laminate is separately supplied in a state where it is exposed to the flame of the burner before passing through the pressure part of the pressure roller. It is seen that the mat and the sponge in the process of passing through the pressure roller, the mat and the sponge is attached in the process of passing through the pressure roller.

The cross-sectional structure produced by the Lyrex-sponge-mat laminate manufacturing process is that as shown in b, Lyrex is attached to one surface of the sponge, and a mat is attached to the other surface, so that the Lyrex-sponge-mat is sequentially stacked. To have a cross-sectional structure that is integrated.
