The iron core roller tube 10 has a perforated air inlet 12 at one end thereof to allow air to be injected into the iron core roller tube 10, and an inner circumference of the iron core roller tube 10. In the periphery of the outer periphery formed a plurality of air outlet holes 13 (in the present invention, a plurality of air outlet holes 13 are formed in the middle portion of the iron core roller tube (10).) Air injected through the 12) to be introduced into the air outlet (13).

The rubber tube 20 is open at both ends and has a tubular shape having a ring cross section, and is rubberized in the longitudinal direction on the outer circumference of the iron core roller tube 10. That is, the rubber tube 20 is fitted in the longitudinal direction on the outer periphery of the iron core roller tube 10 to form an integral with the iron core roller tube 10. (To this end, it will be obvious that the rubber tube 20 should have a relatively larger inner circumferential diameter than the iron core roller tube 10.)

Such a rubber tube 20 may be tensioned and compressed by having a rubber material having an elastic material as its name. If the tension and compression are possible according to a user's selection, other materials may be used.

As described above, when the rubber tube 20 is installed in the outer periphery of the iron core roller tube 10, the iron core roller tube except for the interruption portion of the iron core roller tube 10 in which a plurality of air outlet holes 13 are formed perforated. Adhesive (A) is applied to and attached to both ends of the outer circumference of (10) so that the iron core roller tube 10 and the rubber tube 20 are locally bonded at both ends where the air outlet hole 13 is not formed. do.

This will be possible.

The metal pipe 30 is protruded in the longitudinal direction on the outer periphery of the rubber pipe 20, and has a tubular shape of a ring cross section with both ends open and empty inside.

That is, as the metal tube 30 is fitted to the outer periphery of the rubber tube 20 to form an integral, for this purpose, the size of the inner circumferential diameter of the metal tube 30 should be larger than the inner circumferential diameter of the metal tube 30. will be.

Of course, by attaching and applying the adhesive (A ') between the metal tube 30 and the rubber tube 20, it is possible to increase the mutual adhesion.

Such a metal tube 30 may be an iron or nonferrous material (Al (aluminum), Stainless Steel (SUS), Fe (iron), etc.) may be used.

In addition, the surface of the metal tube 30 may be plated or coated with various paints to form a protective layer 40 to prevent corrosion and abrasion.

Hereinafter will be described a manufacturing method of a preferred embodiment of the present invention having the configuration and structure as described above.

1. In the inner circumference of the iron core roller tube 10 having a tubular shape, forming a plurality of air outlet holes 13 communicating with the outside (S100): at one end to inject air into the tubular body Perforations are formed in the air inlet 12, and a plurality of air outlet holes 13 are formed in the periphery of the inner circumference so that air introduced into the air inlet 12 may be discharged to the outside.

Here, the air injected into the iron core roller tube 10 is not completely discharged to the outside, but serves to inflate the rubber tube 20 externally formed on the outer circumference of the iron core roller tube 10 to the outside.

2. Insulate the rubber tube 20 in the longitudinal direction of the iron core roller tube 10, but apply an adhesive (A) to both ends of the outer periphery of the iron core roller tube 10, the air outlet hole 13 is not formed Step of adhering the iron core roller tube 10 and the rubber tube 20 to each other (S200): while the rubber tube 20 in the outer periphery of the iron core roller tube 10, the iron core roller tube 10 and the rubber tube (20) as a step of joining each other, the remaining portion except the formation position of the air outlet hole 13 perforated in the inner periphery of the iron core roller tube (10), that is, at both ends of the outer periphery of the iron core roller tube (10) The adhesive A is applied or adhered to a predetermined thickness.

As a result, the rubber tube 20 fitted to the outer circumference of the iron core roller tube 10 may have an adhesive portion ① bonded to each other on both end portions of the iron core roller tube 10. (For convenience of explanation, the part to be bonded is called an adhesive part (①), and the part that is not bonded is called a non-adhesive part (②).)

3. The step of externally iron or non-ferrous metal tube 30 in the longitudinal direction of the rubber tube 20 (S300): by fitting the metal tube 30 to the outer periphery of the rubber tube 20, the rubber tube In order to bond the 20 and the metal tube 30 to each other, an adhesive A 'may be attached or applied to the outer circumference of the rubber tube 20.

At this time, the air injected into the iron core roller tube 10 is introduced into the air outlet hole 13 between the iron core roller tube 10 and the rubber tube 20 while expanding the rubber tube 20, the iron core roller tube 10 The adhesive strength can be adjusted by adjusting the amount of adhesive (A ') attached or applied to the outer circumference of the rubber tube 20 in proportion to the pressure between the rubber tube and the rubber tube 20.

4. Plating the surface of the metal tube 30, or coating with a paint (S400): to prevent corrosion and abrasion of the metal tube (30) or plated with various materials or coating with a variety of paint materials such as primers By doing so, the protective layer 40 is formed.

5. Injecting air into the inside through the air inlet 12 formed in one side of the iron core roller tube 10, the rubber tube 20 to the outside by the high pressure of the air discharged to the plurality of air outlet holes (13) Step of expanding (S500): After forming the roller as described above, if continuously injecting air into the iron core roller tube 10, the air in the iron core roller tube 10 is not discharged out and gradually high pressure The high pressure air is introduced between the iron core roller tube 10 and the rubber tube 20 (between the iron core roller tube 10 outer circumference and the rubber tube 20 inner circumference) through a plurality of air outlet holes 13. The rubber tube 20 capable of tension and compression is inflated outward.

That is, since the iron core roller tube 10 and the rubber tube 20 are bonded to each other only by the adhesive (A), due to the high pressure of the air discharged through the plurality of air outlet holes 13, the iron core The suspension of the rubber tube 20, which is a non-adhesive portion (②) of the roller tube 10 and the rubber tube 20, swells and expands.

6. After injecting air so that the rubber tube 20 is expanded to a predetermined level desired by the user, sealing the air inlet 12 (S600): a plurality of rollers are opposed to each other, and a plurality of rollers are used. The transfer member (P), such as a functional film to the compression to be able to transfer, according to the thickness and type of the transfer member to be compressed between the plurality of rollers, the user is injected amount of air into the iron core roller tube (10) It is possible to control, thereby adjusting the injection amount of the air is the same as saying that can adjust the high pressure of the air for expanding the rubber tube (20).

Accordingly, the user injects air so that the rubber tube 20 is expanded to a predetermined level desired by the user, and when the rubber tube 20 reaches a predetermined level, the user seals the air inlet 12 so that the iron core roller tube 10, that is, inside the roller Due to the high pressure of the air of the rubber tube 20 is expanded, and consequently to keep the roller in an expanded state.

Of course, due to the expansion of the rubber tube 20, the metal tube 30 of the iron or non-ferrous material that is fitted to the outer periphery of the rubber tube 20 can also be bent to a predetermined level at the same time as the rubber tube 20, such In proportion to the pressure to expand the rubber tube 20, the metal tube 30 to be bent together with the rubber tube 20 is applied between the rubber tube 20 and the metal tube 30 so as to be firmly bonded to the rubber tube 20 It will be necessary to adjust the amount and thickness of adhesive A 'attached. Of course, when the pressure of the air applied between the rubber tube 20 and the metal tube 30 is low, the adhesive (A ') may not be used. In other words, when air is continuously injected into the iron core roller tube 10 to become a high pressure and the rubber tube 20 expands, due to the expansion force of the rubber tube 20, between the rubber tube 20 and the metal tube 30. Even if there is no adhesive (A ') in the contact is fixed to each other, when the adhesive (A') between the rubber tube 20 and the metal tube 30 is used to expand the rubber tube 20 to the outside The rubber tube 20 and the metal tube 30 through (A ') will be more securely bonded.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Various modifications and changes may be made without departing from the scope of the appended claims.
