A conventional inner cylinder roll 10 in which protrusions 11 are formed on the outer peripheral edge and step edges 12 are formed on both sides of the protrusions 11; First and second outer cylinder rolls (30, 40) one end of which is fitted outside the step (12) and which forms an inner space (13) between the outer cylinder roll and the inner cylinder roll (10); A pressure regulating roll (20) inserted and fitted in the interior space (13); An envelope roll (50) coupled to the outer periphery of the inner barrel (10); .

The first and second outer cylinder rolls 30 and 40 are coupled to each other by interference fit while being firmed outside the step 12.

The first and second outer cylinder rolls 30 and 40 are formed such that a groove 14 is formed on both sides of the protruding portion 11 with one end of each of the first and second outer cylinder rolls 30 and 40, 14 are brazed to fix the first and second outer barrel rolls (30, 40) to the inner barrel roll (10).

The pressure regulating roll 20 absorbs the pressing force concentrated on both sides of the pressure regulating and horizontal holding rolls to uniformly apply a pressing force in the longitudinal direction of the film member moving between the plurality of press regulating and horizontal holding rolls So that it can be provided with an elastic member.

The pressing roll 20 may be made of rubber or silicone.

The sheath roll 50 may be made of any one of metal, paint, rubber, silicone, urethane, ceramic, and epoxy.

The prior art also includes a step S100 of forming a protrusion 11 at a middle portion of the inner barrel 10 and forming a step 12 on both sides of the protrusion 11; A step (S200) of fitting the pressure regulating rolls 20 whose hardness is adjusted in accordance with the pressing force applied to the rolls, into the both inner side spaces 13 of the projections 11; A step (S300) of heat shrinking and engaging one end of each of the first and second outer rolls (30, 40) outside the step (12); (S400) brazing both sides of the protruding portion (11) fitted at one end of the first and second outer barrel rolls (30, 40); (S500) of fitting the outer skin roll (50) to the outer periphery of the inner barrel roll (10).

The inner barrel roll 10 is a circular tubular body having an empty interior. Both end portions of the inner barrel roll 10 are fitted into a shape protruding from the rotary shaft 15, and both end portions are sealed.

In addition, a protruding portion 11 protruding toward the outside is formed in the outer periphery stop portion of the inner barrel roll 10 so that the diameter of the intermediate portion is larger than both ends of the outer periphery, 11 are formed with stepped portions 12 on both sides thereof in a step-like manner.

In other words, protruding portions 11 are formed on the outer peripheral edge portion of the inner barrel roll 10, and diameters of the protruding portions 11 are smaller than the maximum diameter of the protruding portions 11, So that the step 12 having a larger diameter than the outer peripheral diameter is formed. As a result, a stepped shape is formed from the projecting portion 11 toward the outer circumferences on both sides of the inner barrel roll 10.

The first and second outer cylinder rolls 30 and 40 are fitted to the outer periphery of the inner cylinder roll 10. The first outer cylinder roll 30 is fitted on one side of the inner cylinder roll 10, The outer cylinder rolls (40) are fitted on the other side of the inner cylinder roll (10). (Of course, since the first and second outer cylinder rolls 30 and 40 have the same shape and both sides of the inner cylinder roll 10 are symmetrical on both sides, even if the directions of the first and second outer cylinder rolls 30 and 40 are changed It will not matter.)

The first and second outer barrel rolls 30 and 40 have the same shape as each other. The first and second outer barrel rolls 30 and 40 have a pipe shape in which the inside is empty and both ends are opened.

One end of the first outer barrel roll 30 is fitted to one side of the inner barrel roll 10 and the inner circumferential edge of one end of the first outer barrel roll 30 contacts the outside of the step 12 formed on one side of the inner barrel roll 10 One end of the second outer cylinder roll 40 is fitted to the other side of the inner cylinder roll 10 and the inner circumference of the one end of the second outer cylinder roll 40 is fitted to the other side of the inner cylinder roll 10, So as to be brought into contact with the outer side of the formed step 12 and to be prevented.

When the first and second outer cylinder rolls 30 and 40 and the interference fit portion of the inner cylinder roll 10 are cooled (air cooling or the like), they have a coupling structure that never fails to mutually exist. (The length D of the step 12 on both sides of the inner barrel roll 10 is 200 to 300 mm in the present invention. Therefore, the first and second outer rolls 30 and 40 are each shrunk outside the step 12 The constrained length will also be the same as the step 12 length.)

Brazing is performed for more reliable coupling between the first and second outer tube rolls 30 and 40 and the inner tube roll 10 in addition to the interference fit through the heat shrinking.
