The present invention relates to an abrasive paper coated with an abrasive applied to a surface of a substrate made of paper or textile paper and an apparatus for manufacturing the same. More specifically, the abrasive paper is wound in rolls a plurality of times and formed in parallel at a predetermined interval. The present invention relates to a rolled abrasive paper and a cutting line manufacturing apparatus, wherein a cutting line is provided and a plurality of through holes are formed along each cutting line.

In general, abrasive paper is a kind of abrasive tool that is applied by applying abrasive to the surface of the substrate made of paper or textile paper, and it is used to polish the parts, grooves, and circular parts where air bubbles are generated during painting or mold such as wood, lacquer, furniture, and automobile. Used to remove metal rust.

Silicon carbide is mainly used as the abrasive constituting the abrasive paper, and the silicon carbide is pulverized into powder and then bonded to a certain mesh according to the specification of the abrasive paper, meaning that as the standard part number increases, the high mesh powder polishing material is applied. Fine grinding work is possible.

Such abrasive paper has a predetermined thickness as shown in FIG. 1, and its shape forms a square including a square. On the reverse side, a printing surface indicating the manufacturer's specification, etc., including the specification of the abrasive paper is formed, and an abrasive is coated on the surface. .

The abrasive paper as described above does not escape the rectangular shape of the thin plate and occupies a lot of storage volume, and has been used by cutting the abrasive paper using a cutting tool such as scissors or a knife according to the use or range. Therefore, when using the cutting tool, there was a problem causing damage to the cutting tool due to the coarse friction and strong strength of the abrasive. In addition, the conventional abrasive paper is sold in the form of a square of thin plate, so it has to be purchased beyond the intended use or range, which causes economic losses. The introduction of the list price was difficult.

Therefore, the present invention has been devised to solve the above problems, and because it is a roll-shaped abrasive paper, it takes up less storage volume, and is provided with a tear line in the roll-type abrasive paper, so that the abrasive paper can be easily cut out without using a cutting tool. The bar code is provided in between so that only the amount needed for polishing can be purchased, and the purpose is to improve workability and economic efficiency.

Roll-shaped abrasive paper with a perforated line according to an embodiment of the present invention for achieving the above object is wound in a roll form a plurality of times, provided with a perforated line formed in parallel at a predetermined interval, a plurality of along each perforated line Characterized in that the through-hole is formed. In addition, the rolled abrasive paper is provided with a bar code on the back surface of the base between the cutting line, characterized in that the V-shaped groove is provided on at least one end of the cutting line.

In another embodiment of the present invention, the rolled abrasive paper is formed of an abrasive part surface coated with an abrasive in a longitudinal direction at a center portion formed at regular intervals from both ends, and a non-abrasive part surface on which no abrasive material is applied to both sides of the abrasive part surface. It is characterized by. In addition, the rolled abrasive paper is characterized in that at least one or more double-sided adhesive member is provided between the non-polishing portion surface and the back surface of the substrate.

Hereinafter, the configuration and operation of the present invention will be described in more detail with reference to the accompanying drawings.

2 is a perspective view illustrating a rolled abrasive paper provided with a cutting line 10, a barcode 11, and a V-shaped groove 12, which is an embodiment of the present invention.

As shown in FIG. 2, the abrasive paper is wound a plurality of times in the form of a roll, and has a perforated line parallel to the substrate surface 13 and the substrate back surface 14 formed of a paper or textile paper coated with an abrasive and spaced at regular intervals. (10) is provided. The cutting line 10 is easily cut without a cutting tool because it is cut into a plurality of through holes along the cutting line. The interval between the perforations can be varied in various ways depending on the use and shape of the abrasive paper. For example, 10cm, 40cm, 50cm, 1m, etc. can be spaced apart. It is also possible to provide a cut line by forming a groove in the surface of the base body 13 instead of the cut line 10 formed by a plurality of through holes.

The rolled abrasive paper is preferably provided with a bar code 11 containing specific information printed by a bar code printer on the back surface 14 between the perforations 10. Since the barcodes 11 are provided one by one between the perforated lines 10, the barcodes 11 can be sold in units of one or more by the barcode detector according to the working purpose or range.

Preferably, the rolled abrasive paper is provided with a V-shaped groove 12 at at least one end of each cut line 10. By providing the V-shaped grooves 12, the abrasive paper can be cut more easily. Although the V-shaped groove 12 may be provided only at one end, the V-shaped groove 12 is provided at both ends, which is more preferable since it can be easily cut regardless of the direction. In addition, the length of the abrasive paper can be confirmed by checking the number of the V-shaped grooves 12 even in the state of being wound in a roll form. For example, if the interval between the perforations 10 is 1 m and the number of V-shaped grooves 12 is 10, the length of the abrasive paper is 10 m.

Roll-type abrasive paper provided with the cut line of the present invention may be used by cutting along the cut line 10 immediately, but as shown in FIG. 4, since the roll-type abrasive paper has a through hole 20 in the center, the holder 21 in the through hole 20 is provided. ) It can be easily stored and cut off when connected.

3 shows that the abrasive surface 13a and the non-abrasive surface 13b, which are another embodiment of the present invention, have a cutout line 10, a barcode 11, a V-shaped groove 12, and a double-sided adhesive member 15. A perspective view showing rolled abrasive paper provided.

As shown in FIG. 3, the rolled abrasive paper is not formed by applying an abrasive to the entire surface of the substrate, and has an abrasive portion surface 13a coated with an abrasive in a longitudinal direction to a central portion formed at regular intervals from both ends. It is formed with the non-abrasive part surface 13b in which the abrasive | polishing agent was not apply | coated to both sides of the grinding | polishing part surface 13a. The width of the polishing surface 13a and the non-abrasive surface 13b is adjusted according to the use or range of the abrasive paper. The reason for distinguishing the abrasive surface 13a and the non-abrasive surface 13b is to prevent safety accidents that may occur when the abrasive paper is directly gripped in the normal polishing operation, and improve the working efficiency. This is because the abrasive paper can be bonded together with the abrasive aid 22. That is, the back surface 14 of the substrate opposite to the polishing surface 13a is located under the polishing aid 22, and the back surface 14 of the substrate opposite to the non-abrasive surface 13b is formed of the polishing aid 22. It will be located to the side or top. In addition, the abrasive can be saved by applying the abrasive only to the polishing part surface 13a necessary for polishing. It is also possible to form bends on the polishing surface 13a and the non-abrasive surface 13b, respectively, to facilitate engagement with both bottom edges of the polishing aid 22.

In addition, as shown in FIG. 5, the rolled abrasive paper is preferably provided with at least one double-sided adhesive member 15 between the non-abrasive portion surface 13b of the substrate and the back surface 14 of the substrate.

In other words, the back surface 14 of the substrate opposite to the polishing surface 13a is positioned below the polishing aid 22, and the back surface 14 of the substrate opposite to the non-abrasive surface 13b is located up to both sides or the top thereof. Since the abrasive paper and the polishing aid 22 are coupled by the double-sided adhesive member 15 attached to the 14, workability can be improved to prevent the back surface 14 from slipping from the polishing aid 22. It becomes possible. In addition, since the roll-shaped abrasive paper of the present invention is wound in a roll form, a predetermined elastic force may be generated and a predetermined release may occur, so that the non-abrasive part surface 13b and the back surface 14 of the substrate are formed by the double-sided adhesive member 15. Because of this combination, it is also possible to prevent a predetermined loosening.

On the other hand, the rolled abrasive paper configured as described above may be provided with a cutting line 10, a bar code 11 and a V-shaped groove 12, like the rolled abrasive paper according to an embodiment of the present invention described above.

The manufacturing apparatus according to an embodiment of the present invention for forming the tear line of the rolled abrasive paper provided with the tear line of the present invention described above is as follows.

As shown in FIG. 6, a device for forming a perforation line includes an abrasive paper strip 30 having an abrasive applied to a surface of a substrate made of paper or textile paper, and a steel blade 42 coupled to a frame, respectively. It is composed of a first roller 40 provided, and a second roller 41 located above the first roller 40.

The steel blade 42 is a device for forming the cutting line 10 is coupled to the groove formed in the longitudinal direction of the first roller 40. Therefore, since the interval of the cutting line 10 is determined by the circumferential length of the first roller 40, the interval of the cutting line 10 can be adjusted by changing the length of the circumference of the first roller 40. In addition, grooves may be formed in the circumference of the first roller 40 at a plurality of equal distances, and a plurality of steel blades 42 may be coupled to adjust the distance between the perforations 10. For example, the length of the first roller 40 window is 1 m, and when two steel blades 42 are combined, the distance between the perforations 10 is 50 cm.

 The steel blade 42 is preferably a saw blade-shaped steel blade 42 that can form a plurality of through holes. Of course, instead of the saw blade-shaped steel blade 42, it is also possible to form a cutting line by attaching a steel blade (not shown in the figure) without a saw blade to form a groove in the abrasive paper strip 30.

The surface of the second roller 41 is an elastic material and acts as a buffer while applying pressure to form a plurality of through holes by the steel blade 42. It is preferable to use a rubber-based material as the elastic material.

Looking at the operation relationship of the cut line manufacturing apparatus components are as follows.

Between the first roller 40 and the second roller 41, the pre-manufactured abrasive paper strip 30 proceeds, and the first roller 40 is formed on the back surface of the substrate of the abrasive paper strip 40 ( 14) and rotates by the motor in the same direction as the traveling direction of the abrasive paper at the same speed as the progress of the abrasive paper strip 40. The second roller 41 rotates in a direction opposite to the rotational direction of the first roller 40 and applies pressure to the steel blade 42. Thus, a plurality of through holes are formed in the abrasive paper strip 30 by the steel blades 42, and the cutting lines 10 at equal intervals are formed by the first roller 40 rotating at constant speed.

The abrasive paper strip 40 having the cutting line 10 manufactured by the above-mentioned cutting line manufacturing apparatus is cut to a certain width by a separate cutting device and produced in various standards, and is wound in a roll shape by a separate roller. This provided abrasive paper is completed. In addition, it is also possible to form the V-shaped groove 12 at least at one end of the perforated line through a separate V-shaped groove cutting device.

In addition, before or after the process of forming the perforated line 10, it is also possible to manufacture by forming a bar code 11 containing information such as the size and price of the abrasive paper on the back surface 14 of the substrate with a bar code printing device.

The present invention described above can be embodied in many different forms without departing from the spirit or main features thereof. Therefore, the above embodiments are merely examples in all respects and should not be construed as limiting.

According to the embodiment of the present invention having the configuration as described above, because it is a roll-shaped abrasive paper, it takes up less storage volume, and the cutting line is provided on the roll-type abrasive paper so that the abrasive paper can be easily used without using a cutting tool, and between the cutting lines. The bar code is provided so that it can be purchased only as needed for polishing, thereby improving workability and economic efficiency.
