Description

[Detailed Description of the Invention] This invention relates to an apparatus for manufacturing a masking tape having a non-adhesive portion on the adhesive surface.

The masking tape manufactured by the present invention is expected to be used as described below, for example.

In general, interior materials for automobiles include a core material made of hardboard or the like formed into a predetermined shape and covered with a vinyl skin sheet. Then, when covering the skin sheet,
In recent years, a method called vacuum forming method has been adopted.
This vacuum forming method is a method in which the air between the core material and the skin sheet is suctioned and discharged, so that the skin sheet is brought into close contact with the core material and follows the shape of the core material. In recent years, this has been often done to give interior materials a sharp shape.

Now, in some cases, the core material is previously penetrated with openings at appropriate locations during its molding stage. This is because a resin clip is used, for example, when attaching an interior material to the body of an automobile, and the above-mentioned opening is provided for attaching this clip.

However, in the case where the core material s has an opening k as described above, when the above-mentioned vacuum forming method is performed,
The skin sheet hs will be sucked into the opening k, causing the product to wrinkle. Therefore, one idea to avoid this is to close the opening k with an adhesive tape t or the like prior to vacuum forming (see FIG. 1).

However, if the opening is closed using ordinary adhesive tape t or the like, it will be difficult to attach the clip c. This is because the normal adhesive tape t is completely adhered to the surface around the opening k, and the clip c is stuck between the core material s and the adhesive tape t.
This is because there is no gap for inserting the mounting base C1. In addition, adhesive tape t is used on the closed side of opening k.
This is because the adhesive surface of the clip C will be exposed, and if the clip C is inserted, it will stick to it, making attachment of the clip C cumbersome.

Separately, as shown in Figure 2, masking tape mt is prepared by pasting paper tape or the like to the center of the adhesive surface of adhesive tape t to form a non-adhesive part hn there.
According to this method, the above-mentioned problem regarding attachment of the clip c can be solved. In other words, the non-adhesive part hn of this masking tape mt makes the opening k
When the non-adhesive part hn is not adhered to the core material s, a gap is formed between the core material s and the masking tape mt, thereby securing a space for inserting the clip c into the mounting base C1. Ru. Also, since the non-adhesive part hn made of paper tape is exposed at the opening k, the clip c
The clip C can be easily attached without sticking to the surface (see Fig. 3).

An object of the present invention is to provide an apparatus that can easily and efficiently manufacture such a masking tape having a non-adhesive portion on the adhesive surface.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is the base, 2 is the base 1
This is a tape stand erected above, and a tape reel 3 around which a tape with release paper is wound is attached to the stand 2 so as to be rotatable and detachable.
And the tape with release paper is adhesive tape 4 from here.
and release paper 5, and are fed out. Also,
Each transport path of the adhesive tape 4 and release paper 5 includes
A pair of tension rollers 6A, 6B, 7A, and 7B supported by the side wall 1A of the base 1 are interposed to transport the adhesive tape 4 and the release paper 5 under tension. Further, in the transfer path of the release paper 5, a cutter mechanism 8 is interposed between the tension rollers 7A and 7B. The cutter mechanism 8 includes a drive gear 9 that is connected to a drive source (not shown) via a speed reduction mechanism and rotated at a slow speed, and a cutter roller 10 that is connected to the drive gear 9 and rotated at a slow speed in the direction of the arrow shown in the figure. The cutter roller 10
is equipped with a pair of flanges for guiding the transfer of the release paper 5, and a driven gear 11 meshed with the drive gear 9 is fitted on the outside thereof,
The roller shaft 12 has two cutters 13 shown in the figure,
13 are fitted at predetermined intervals (fifth
(see figure). A sharp cutter blade is formed on the outer peripheral edge of both cutters 13, 13, and each slides on the lower surface of the release paper 5, so that both sides of the release paper 5 can be cut off by a predetermined width.

In addition, each of the tension rollers 6A, 6B, 7
Among A and 7B, the one 7B closer to the pinch roller PR in the transfer path of the release paper 5 is a roller with a guide groove that can guide the transfer of the release paper 5 whose width has been reduced, and the other tension rollers 6A, 6B, 7A
is a roller with flanges on both sides so as to guide the transfer of the adhesive tape 4 or the release paper 5.

The pinch roller pair PR consists of a drive roller 14, one side of which is connected to the aforementioned drive source (not shown) and is rotationally driven in the direction of the arrow in the figure, and a driven roller 15, which is disposed opposite thereto. The release paper 5 can be fed out while being bonded to the adhesive tape 4 again. In order to cut the reapplied tape with release paper to a desired length, a cutter stand 17 on which a cutter 16 is supported upward is provided at the frontmost portion of the base 1.

Subsequently, the operation and effect of this example configured as described above will be specifically explained.

A pair of pinch rollers PR is driven by a drive source (not shown), and the tape with release paper is separated into the release paper 5 and the adhesive tape 4 and fed out from the tape reel 3. Then, the adhesive tape 4 is transported under tension via both tension rollers 6A and 6B, while the release paper 5 is reduced in width as it passes through the cutter mechanism 8 during its transport. That is, the drive gear 9 is driven by a drive source (not shown).
When the cutter roller 10 is rotated via the driven gear 11, both cutters 13, 13 are rotated together at a slow speed, so the release paper 5 is guided by both flanges of the cutter roller 10,
The width is reduced at intervals set at 3 and 13. Then, both sides of the release paper 5 are cut off onto the base 1, while the central part remains as it is on the tension roller 7.
It is transferred to the pinch roller pair PR via A and 7B. Then, at the pinch roller pair PR, the adhesive tape 4 and the release paper 5 whose width has been cut are pasted together again, and then cut to a desired length by the cutter 16 of the cutter stand 17. Thus, the adhesive tape 4 as shown in FIG.
A masking tape mt is obtained in which a release paper 5 of a predetermined width is attached to the center of the adhesive surface of the masking tape mt.

In this way, according to the apparatus of this example, a desired masking tape mt can be easily obtained using a commercially available tape with release paper. Furthermore, the device itself is compact and can be carried around.

Although this example shows an example in which the operator tears off the tape after passing through the pinch roller pair PR, it is also possible to automatically cut the tape to a fixed size instead of this, or cut the tape at this stage. If not required, a winding reel or the like may be used to wind up the windings one after another.

As described in detail above, the present invention is provided with a transfer path for separating the tape with release paper into the adhesive tape and the release paper, feeding it out, and then bonding the adhesive tape and the release paper together again, as well as transporting the release paper. The gist is that a cutter mechanism is installed in the middle of the path to cut the release paper by a predetermined width. With this configuration, the present invention can efficiently produce a desired masking tape even if a commercially available tape with release paper is used. Moreover, the device itself may have a simple structure;
From these facts, it can be said that the device of the present invention has high practical value.
