Description

  The present invention relates to a tape measure tape.

  Conventionally, a tape tape manufactured using a glass fiber woven fabric as a thin plate base material which is a main body of a tape measure tape has excellent flexibility on the surface of the tape for the purpose of preventing fraying and reinforcement of the glass fiber. A vinyl chloride (vinyl chloride) resin is coated, but in order to strengthen the adhesion of the vinyl chloride resin, a vinyl chloride sol as an adhesion improver is applied to the core material formed of glass fiber, and then the vinyl chloride resin is applied. Yes. That is, the vinyl chloride sol functions as an adhesive between the vinyl chloride resin and the glass fiber, and the vinyl chloride resin can be sufficiently adhered to the base material formed of the glass fiber.

  However, since it is indispensable to apply a vinyl chloride sol in order to sufficiently adhere the vinyl resin to the glass fiber base material, the cost of the vinyl chloride agent and the cost of the vinyl chloride coating process are reflected in the commercial price, and the commercial price is high. The market competitiveness was weak.

  The object of the present invention is to provide a tape measure tape that can be applied directly to a base material (the main body of the tape tape) with a coating material such as a vinyl chloride resin, thereby reducing manufacturing costs and increasing market competitiveness. There is in doing so.

  In order to solve the above-described problem, a tape for a tape measure according to the present invention is a tape for a tape measure in which at least both front and back surfaces of a base material are covered with a covering material. The dimples are covered in a filled state.

  Further, the base is made of a fiber woven fabric.

  Further, the base is made of a synthetic resin material.

  Further, the base is a film member made of a synthetic resin material.

  Further, the base is made of a metal material.

  Further, the coating material is characterized in that a soft resin is a main component.

  In addition, the covering material is mainly composed of a vinyl chloride resin.

  Moreover, the said base material is arc-shaped in the tape width direction for tape measures, It is characterized by the above-mentioned.

  Further, the present invention is characterized in that a large number of notches are provided on the sides in the longitudinal direction of the base material.

  Moreover, the scale for a measurement is printed on the base material as what can see through the said coating | covering material.

  In addition, a material having an antibacterial action is added to the covering material.

  Moreover, the scale for a measurement is printed on the said coating | covering material, It is characterized by the above-mentioned.

  In addition, a material having an antibacterial action is added to the paint for displaying the scale.

  According to the tape measure tape of the present invention, since the coating material can be directly applied to the base material which is the main body of the tape measure tape, at least the cost of the vinyl chloride sol agent and the cost of the vinyl chloride sol coating process can be reduced, and the market competition A tape with high strength can be provided.

  And, when a film made of a synthetic resin material is used for the base material, there is also an advantage that the thickness can be made thinner than the base material of fiber fabric such as glass fiber, which makes it flexible even though it is a solid tape. It has excellent effects, and the case can be downsized.

  In addition, if you select the width and thickness of the base material that will be the main body of the tape measure tape, you can fully adapt it to the tape measure of a conventional steel tape. Since the mainspring spring for winding the tape can also have a low torque, the weight of the tape and the mainspring spring, which greatly affects the weight of the tape measure, can be reduced so that the weight of the tape measure itself is determined. It is possible to provide a very light tape measure like never before.

  In addition, the tape measure of the steel tape has a risk of electric shock depending on the place where it is used, so we are careful about the extension of the tape and the handling of the extended tape, but it is non-conductive so that it can be applied to the specifications of the steel tape. If the tape for tape measure of the present invention is configured using the base material of the present invention, it is difficult to bend compared to the conventional non-conductive tape which is easy to bend without bending, so the risk of electric shock can be reduced to zero and measurement work Can be easily and safely performed.
