The present invention relates to a release paper for sealing material formed with a cutout groove and a manufacturing apparatus for manufacturing the same, and more particularly to one or both sides of the release paper for sealing material used in a glass window of a vehicle or a building or a general assembly machine. The present invention relates to a release paper for a sealing material having a cutting groove formed therein so that the rubber sealing material can be bent freely even when the release paper is attached thereto, and a manufacturing apparatus for manufacturing the same.

In general, the sealing material prevents the inflow of water or wind through gaps between members or parts (hereinafter referred to as the adherend) in the windows of automobiles or buildings or general assembly machines, and prevents noise or vibration caused by collision between the adherends. Use for the purpose of prevention.

For example, an automobile side glass is fixed to a vehicle body by using a rubber sealing material. The rubber sealing material is a wire-shaped extruded foam having a large circular or rectangular cross section, and an adhesive applied uniformly to a certain thickness on the outer circumferential surface thereof. The layer and the tape-shaped release paper adhered longitudinally along the outer peripheral surface of one side of the said rubber sealing material.

In general, the rubber sealing material used in the side glass for automobiles is convenient to transport, store and use by winding a rubber sealing material having a length of 5 ~ 30m or more in the form of a coil or a roll. By attaching the release paper to the outer circumferential surface of the rubber sealing material it is possible to wind the rubber sealing material having a strong adhesive force in the form of a coil or a roll. In addition, the release paper not only prevents the worker's hand or tool from sticking to the rubber sealing material when attaching the rubber sealing material, but also prevents the adhesive layer from being contaminated by foreign matter.

1 is a perspective view showing an example of a rubber sealing material attached to a conventional release paper. As shown, the rubber sealing material 1 is wound in a coil shape, and a release paper 2 is attached between the neighboring rubber sealing materials 1. At this time, the release paper 2 has a width enough to completely cover the rubber sealing material 2 in the form of a tape. Therefore, the tape-shaped release paper 2 is inferior in bending property in the horizontal direction as compared with the wire-type rubber sealing material 1.

For example, when the rubber sealing material 1 is used for a glass panel for automobiles, the rubber sealing material 1 and the release paper 2 are cut to the required length, and the rubber sealing material 1 is formed by the release paper 2. In the attached state, adhere along the adhesive part of the glass panel. Then, the release paper 2 attached to the rubber sealing material 1 is removed, and the glass panel is tightly fixed to itself in the state where the pressure-sensitive adhesive layer is exposed.

As described above, in order to fix the adherend using the rubber sealing material 1, the rubber sealing material 2 should be adhered with the release paper 2 attached along one side of the adherend. (1) When the adhesive portion of the adherend to be bonded is severely bent or bent, the rubber seal 1 is made of a flexible rubber material, which is relatively easily bent, but the release paper 2 has a wide tape shape and thus is horizontally Since the rubber sealing material 1 is hardly bent to adhere to the bent portion of the adherend, when the release paper 2 is forcibly bent, the release paper 2 is detached from the rubber sealing material 1 or severely wrinkled, so that the defect is prevented. There is a problem that occurs. In addition, in order to solve this problem, a worker may make an incision groove in the release paper for each bent portion by using scissors or a knife. There was a problem falling.

The present invention is to solve the above-mentioned problems, in particular, the release paper for the sealing material formed with a cut groove that can be smoothly attached to the rubber sealing material by bending the release paper even when the portion to be bonded to the rubber sealing material is severely bent or bent. And it is an object to provide a manufacturing apparatus for manufacturing the same.

In order to achieve the above object, a release paper for a sealing material having a cut groove formed therein according to the present invention, in a tape-shaped release paper attached to a rubber sealing material, is spaced at regular intervals on one or both edges of the release paper, and a plurality of cut grooves are formed. It is characterized by.

In the release paper for sealing material formed with a cutout groove according to the present invention, the plurality of cutout grooves formed on both edges of the release paper, characterized in that the adhesive portion is formed to face each other or staggered with each other and the sealing material is attached therebetween.

In addition, the plurality of cutting grooves formed on one or both edges of the release paper is characterized in that it is formed orthogonally or inclined with respect to the longitudinal direction of the release paper.

And, in order to achieve the above object, the release paper manufacturing apparatus for a sealing material formed with a cut groove of the present invention, the supply unit for supplying a release paper of the tape shape; An incision having a rotary blade rotating in a horizontal direction to form an incision groove in one or both edges of the release paper; It comprises a tension unit for adding a constant tension to the release paper.

The cutting portion and the rotary blade portion is mounted to the rotary blade to rotate by a motor; It consists of a fixed blade portion disposed on the back of the release paper, the rotary blade is characterized in that forming a cut groove in the release paper while contacting the fixed blade portion.

In the release paper manufacturing apparatus for a sealing material formed with a cutout groove according to the present invention, the cutout portion further comprises an adjustment unit for adjusting the spacing or height of the rotary blades respectively installed on both sides around the release paper.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

Figure 2 is a perspective view showing a rubber sealing material attached to the release paper is formed with a cutout according to the present invention, Figure 3 is a schematic perspective view showing a release paper for sealing material of the present invention in which the cutout is formed in various forms.

As shown in FIG. 2, the rubber sealing material 10 is wound in a coil form, and a release paper 20 is attached to one side of the outer surface of the rubber sealing material 10. The release paper 20 is made of vinyl or paper material, and has a tape shape having a width enough to cover the rubber sealing material 10, and the release paper 20 is adhered to the pressure-sensitive adhesive layer of the rubber sealing material 10. Preferably, it is coated so that it can easily fall off from the pressure-sensitive adhesive layer.

Then, as shown in Figures 2 and 3, one or both edges of the release paper 20 is formed with a plurality of incision grooves 30 at regular intervals. 3 (a) to 3 (d) show various forms of cutouts 30 formed in the release paper 20. First, in Fig. 3 (a), the incision grooves 30 are formed only at one edge of the release paper 20 at regular intervals. The incision groove 30 is formed perpendicular to the longitudinal direction of the release paper. In addition, although the incision groove 30 is shown in the figure so that it may be seen by an eye, in reality, the incision groove 30 may not be seen well visually.

3 (b) is formed so that the incision grooves 30 formed on both edges of the release paper 20 to face each other. In addition, an adhesive part 34 to which the rubber sealing material 20 is attached is formed between the opposing incision grooves 30. In addition, when the adhesive portion 34 pulls the release paper 20 in the longitudinal direction, it is preferable to have a width sufficient to prevent the release paper 20 from being easily torn through the cutout groove 30.

In addition, in Fig. 3 (c), the cut grooves 30 formed at both edges of the release paper 20 are alternately formed. As such, when the cutting grooves 30 are alternately formed, the width of the adhesive part 34 is widened. That is, when pulling the release paper 20 in the longitudinal direction while increasing the depth of the incision groove 30, the width of the adhesive portion 34 can be sufficiently secured so that the release paper 20 is not easily torn.

In addition, the cutting groove 30 formed in the release paper 20 is inclined with respect to the longitudinal direction of the release paper 20 in FIG. As such, the inclined groove 30 may be more easily bent in the release paper 20 at the bent portion. For example, when the release paper 20 is bent in the horizontal direction, the wing portions 33 formed by the cutting grooves 30 overlap each other. As shown in this embodiment, the cutting paper 20 is cut in the traveling direction of the release paper 20. When the groove 30 is formed to be inclined backward, the release paper 20 is more easily bent because the wings 33 formed on the release paper 20 overlap more naturally.

As described above, when the incision grooves 30 are formed at one or both edges of the release paper 20, the release paper 20 is attached when the rubber sealing material 10 is attached to a severely curved section or an angled adherend. It can be bent freely, so that the rubber sealing material 10 can be easily attached to the adherend.

Therefore, when the first driving motor 204 is rotated and the driving roller 206 transmits the rotational force to the drawing roller 203, the release paper 20 surrounding the outer circumferential surface of the drawing roller 203 is in the vertical direction. Will be withdrawn.

In addition, the front surface of the main body 101 is provided with a guide member 207 for guiding the release paper 20 conveyed in the vertical direction by the take-out roller 203 is transported without being left and right. Preferably, the guide member 207 is installed on the upper and lower portions of the cutout 300, respectively. That is, an upper guide member 207 ′ is installed at the upper portion of the cutout 300, and a lower guide member 207 ″ is installed at the lower portion of the cutout 300. A guide groove for guiding the release paper 20 is vertically formed vertically in the center to allow the release paper 20 to pass through the center of the cutout 300.

Subsequently, as shown in FIGS. 4 and 5, the cutout part 300 cuts the groove 30 at a predetermined interval on one or both edges of the release paper 20 drawn out in the vertical direction from the release paper supply reel 201. Forming part. The incision 300 is installed on the front of the main body 101 and the rotating blade portion 310 made of a rotary blade 312 rotating in the horizontal direction, and the fixed blade 322 in contact with the rotary blade 312 It consists of a fixed blade portion 320 made.

It consists of a fixed blade 322 provided to have a car, and a bracket 323 for fixing the plate-shaped fixed blade 322 to the front surface of the main body 101 or the upper surface of the fixing case 313.

Therefore, while the release paper 20 is transported from the top to the bottom, when the rotary blade 312 rotates while contacting the fixed blade 322, the rotary blade 312 and the fixed blade 322 as scissors It acts to form the cutting groove 30 on the edge of the release paper (20). At this time, the length of the cutting groove 30 is determined by the depth of the rotary blade 312 for cutting the release paper 20, the interval between the cutting groove 30 is the rotational speed of the rotary blade 312 and the It is determined according to the conveying speed of the release paper 20.

In addition, the cutting grooves 30 formed at both edges of the release paper 20 to face each other or to cross each other is determined by the height difference of the rotary blades 312 provided on both sides of the release paper 20. That is, when the height of the rotary blades 312 provided on both sides is the same, the cutting grooves 30 facing each other are formed, and if the height difference is placed on the rotary blades 312 provided on both sides, they are formed to be offset from each other. As such, by changing the installation position of the rotary blade 312, the depth or angle of the cutting groove 30, and both the cutting groove 30 to face or stagger is achieved through the adjustment unit 500 to be described later.

On the other hand, the rotary blade 312 may be directly connected to the motor to be rotated (not shown), but as shown in Figure 4 includes a universal joint 340 which is installed perpendicular to the front of the body 101 It is preferable to rotate through the power transmission device 350.
