Abstract

PURPOSE:To shorten the required time in masking work using a masking tape, by making it possible to continuously and efficiently form the masking tapes each partially having a pressure-sensitive adhesive surface to front and back surfaces. CONSTITUTION:When pressure-sensitive adhesive tapes 7a, 7b are passed between press bonding rolls 11 while unwound from winding cores 13a, 13b in such a state that said cores 13a, 13b are supported by a feed-out shaft 10, both tapes 7a, 7b are unwound in such a state that pressure-sensitive adhesive surfaces thereof are opposed and the pressure-sensitive adhesive tape 7a is contacted with a lap roll 12 and pushed downwardly by said lap roll 12 of which the rotary axis is inclined with respective to a frame 9. Therefore, the pressure- sensitive adhesive surfaces of the tapes 7a, 7b are partially laminated between the press bonding rolls 11 to form a masking tape 8.

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, etc., use masking tape made of paper, film, cloth, etc. to separate the painted parts from the non-painted parts. temporary fixing is being carried out.

FIG. 6 is a sectional view showing a state in which a masking material is fixed to an object to be coated with masking tape. In the figure, 1 is the object to be painted, 2 and 3 are the painted and non-painted parts of the object 1 to be painted, 4 is the boundary between the painted part 2 and the non-painted part 3, and 5 is one end 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 masking tape 5 is pasted in advance on the edge of the mask material 6 with the adhesive side protruding, and then the masking tape 5 is pasted onto the non-painted area 3. Be taken. On the other hand, if the boundary 4 is long, first, one side of the masking tape 5 in the width direction is lifted, and then the other side of the masking tape 5 is attached along the boundary 4, and then the mask material 6 A method is used in which the masking material 6 is pasted on the floating side of the masking tape 5, but in this case, the masking material 6 is pasted between the object to be painted 1 and the masking tape 5.
Since it is necessary to paste the mask while inserting it, the masking work is difficult and takes a lot of time.

Therefore, as shown in FIG. 7, two pieces of adhesive tape 7a,
A masking tape 8 is used in which a part of the masking tape 7b is pasted with the adhesive surfaces facing each other, that is, the masking tape 8 has partial adhesive surfaces on the front and back surfaces. 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 done easily and in a short time.

[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, when spraying 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. (1) A masking tape having partial adhesive surfaces on the front and back sides can be continuously produced easily and in a short time. The purpose is to provide a creation device for.

[Means for solving problems]

In order to achieve this object, in the present invention, while unwinding an adhesive tape that is wound around a core and has a skirting agent surface on one side, the adhesive surfaces of two adhesive tapes are placed facing each other, and In an apparatus for making a masking tape in which parts are bonded together, a delivery shaft for supporting the core is attached to a frame, a pressure roll is provided on the frame, and a pressure roll is provided between the delivery shaft of the frame and the pressure roll. Provide a wR adjustment roll to be in contact with the adhesive tape.

[Effect]

When the core on which the adhesive tapes are wound is supported on the delivery shaft and the adhesive tape is passed through the pressure roll while being unwound, at least one of the two adhesive tapes comes into contact with the adjustment roll,
A masking tape is created by pasting parts of two pieces of adhesive tape together with their adhesive surfaces facing each other.
