PREFERRED EMBODIMENT OF THE INVENTION

[0028] In view of the mentioned drawings and according to the numbering used, there can be observed an example of adhesive tape with easily removable flaps at its ends obtained by means of the method object of the invention, and an example of a device for producing said flaps in the tape, which comprises the parts and elements indicated and described in detail below.

[0029] Thus, as can be observed in FIGS. 1 and 2, the method which allows the production of an easily removable flap (100) at the ends of any adhesive tape (1), both at the ends (10) of a segment of the adhesive tape used for fixing to a surface (2), as shown in FIG. 1, and at the end (10) of the tape (1) that is left to be dispensed on a roll, as shown in FIG. 2, comprises the application of a piece of non-adhesive paper (3) adhered to said ends (10) of the tape (1) and having a width (a) less than the width (A) of the tape (1) in which it is applied, such that at said ends (10) the tape (1) is stuck on both sides of the paper (3) located at the center of said end (10) acting like a flap (100) by allowing fingers to be inserted so as to pull on it.

[0030] Furthermore, said piece of non-adhesive paper (3) is preferably adhered to the ends (10) of the tape (1), being cut along with said tape (1) at the time of making each cut in the tape, being fixed to same such that one part of the piece of paper (3) is adhered to the end of the portion of tape (1) being removed as a result of said cutting and the other part of the paper (3) is adhered to the end of the tape (1) left on the roll.

[0031] Preferably, the piece of paper (3) that is adhered to the ends (10) of the tape (1) is a rectangle about three centimeters in length and its width (a) occupies about two thirds of the width (A) of the tape (1) for which it is intended.

[0032] Furthermore, the piece of paper (3) is preferably opaque, such that when the tape (1) is transparent, it is very easy to identify point at which any of the two ends (10) of a segment of tape (1) stuck on a surface (2), as shown in the example of FIG. 1, or the end (10) of the tape (1) left on the roll, as shown in FIG. 2, are located.

[0033] Finally, the method contemplates that the application of the piece of non-adhesive paper (3) adhered to the ends (10) of the tape (1) is preferably performed by using a mechanical device (4) which can optionally be adapted to dispensers already existing on the market for dispensing an adhesive tape (1).

[0034] Considering FIG. 3, it can be observed how, in one embodiment option, the mentioned device (4) comprises, housed along with the reel (5) of the standard roll of adhesive tape (1), the incorporation of: [0035] a second reel (6) of a roll of non-adhesive paper (3), [0036] a series of lower rollers (7) for introducing the web of paper (3) between which said paper (3) passes in a guided manner such that they conduct it to a narrow space or channel (8) defined between two facing support surfaces, an upper support surface (9) and another lower support surface (10) in the example depicted according to the observer's point of view, [0037] a first push button (11), associated in its initial path with a gear rack mechanism (12), and with a first blade (13) located at the end opposite the head of the push button (11), arranged such that each time the push button (11) is actuated, the gear rack (12) advances the web of paper (3) towards said channel (8) while at the same time the blade (13) cuts it, so that the cut rectangular piece of paper (3) can be adhered to the web of the adhesive tape (1) which, in turn, passes through said channel (8), [0038] a second series of upper rollers (14), among which a push roller (14) is contemplated, arranged such that they guide and press the web of the adhesive tape (1) after the channel (8) in which the roll of paper (3) advances, so that it is adhered to it once cut, and [0039] means for moving and cutting the adhesive tape (1), in this case, manual means, being moved upon being driven manually when the user pulls on the end of said paper, and a second push button (15) with a second blade (16) at the opposite end thereof, arranged such that, upon pressing same, it cuts the tape (1) along with the piece of paper (3) since it is placed in a coinciding manner so that there is a part of paper (3) adhered at each cut end (10) of the tape (1).

[0040] It must be understood that said device (4) is only one embodiment since its configuration and elements may vary, comprising, in any case, essentially the following: [0041] the second reel (6) of a roll of non-adhesive paper (3), [0042] the means (7) for introducing and means (12) for advancing the web of paper (3) to a space with means (13) for cutting the paper and means (14) for adhering the cut rectangular piece of paper (3) to the web of the adhesive tape (1), and [0043] the means (16) for moving and cutting the adhesive tape (1), along with the piece of paper (3) placed in a coinciding manner so that there is a part of paper (3) adhered at each cut end (10) of the tape (1).

[0044] FIG. 4 shows the rear part of a portion of the tape (1), with the paper (3) incorporated on both sides of the point of cutting of said paper, which allows obtaining flaps at the respective ends (10) thereof determining said cut.

[0045] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to expand on this explanation so that one skilled in the art will understand its scope and the advantages derived from it, hereby stating that within its essential nature, the invention may be carried out to practice in other embodiments which differ in detail from that indicated by way of example and which will likewise attain the protection that is sought provided that its fundamental principle is not altered, changed, or modified.
