Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an apparatus for producing a masking tape used for so-called masking in painting operations and the like.

[Conventional technology]

When painting the exterior of a house, paper, film, or
2. Description of the Related Art A masking material made of paper, film, etc. is temporarily fixed to an object to be painted using a masking tape made of cloth or the like.

FIG. 6 is a sectional view showing a state in which a masking material is fixed to an object to be painted using masking tape. In the figure, 1 is the object to be painted, 2 and 3 are the painted and unpainted parts of the object 1 to be painted, 4 is the boundary between the painted part 2 and the unpainted part 3, and 5 is one end that is aligned with the boundary 4. A masking tape 6 is attached to the non-painted portion 3, and a mask material 6 has one end attached to the masking tape 5.

Here, if the boundary 4 is short, the best method is to attach the masking tape 5 to the edge of the mask material 6 in advance with the adhesive side protruding, and then attach it to the non-painted area 3. It will be done. On the other hand, if the boundary 4 is long, first, one side of the masking tape 5 in the width direction is raised, and then the other side of the masking tape 5 is pasted along the boundary 4, and then the mask material 6 The masking tape 5 is pasted on the floating side of the masking tape 5, but in this case, it is necessary to insert the masking material 6 between the object to be painted 1 and the masking tape 5 while pasting it, so the masking work is difficult. The disadvantage is that it is difficult and takes a lot of time.

Therefore, as shown in FIG. 7, a masking tape 8 is made by pasting together parts of two adhesive tapes 7a and 7b with their adhesive surfaces facing each other, that is, having adhesive surfaces partially on the front and back sides. It is being used. In this case, first align one end of the adhesive tape 7a of the masking tape 8 with the boundary 4, apply the adhesive tape 7a to the non-painted area 3, and then apply the masking material 6 to the adhesive tape 7b from the front side. Therefore, the work of fixing the mask material 6 can be easily and quickly performed.

[Problem that the invention seeks to solve]

However, when the masking tape 8 shown in FIG. 7 is used, there is a problem in that the masking tape 8 is created manually at the painting work site, and this creation work requires a lot of time. By the way, in the case of spray painting work that requires masking work, about two-thirds of the painting work time is spent on masking work.

This invention was made in order to solve the above-mentioned problems, and is a masking tape that can continuously, easily and quickly create a masking tape having partial adhesive surfaces on both the front and back sides. The purpose is to provide a device for creating.

[Means for solving problems]

In order to achieve this object, in the present invention, while unwinding an adhesive tape wound around a core and having an adhesive surface on one side, the adhesive surfaces of the two adhesive tapes are placed opposite each other, and a part of the adhesive tape is unwound. In the device for making masking tape pasted together, a delivery shaft to support the core is attached to the frame,
A pressure roll is provided on the frame, and an adjustment roll to be in contact with the adhesive tape is provided between the delivery shaft of the frame and the pressure roll.

[Effect]

When the core on which the adhesive tape is wound is supported on the delivery shaft and the adhesive tape is passed through the pressure roll while unwinding, at least one of the two adhesive tapes comes into contact with the adjustment roll, and the adhesion of the two adhesive tapes increases. A masking tape is created in which parts of the tape are pasted together with the agent surfaces facing each other.
