Embodiment 1
[0029] For a scotch tape with a width of W=12mm, a winding reel radius of R0=18mm, and a tape thickness of d=50um, a five-ring color alternating oblique stripe pattern is used as shown in Figure 4(b), and the colors of the five oblique stripes are red, green and blue in turn. Orange gray, oblique line width 0.2mm, the structure of the manufactured tape is shown in Figure 1, where 1 is the adhesive layer, 2 is the pattern layer, 3 is the BOPP substrate, and d is the thickness of the tape. The pattern is loaded onto the substrate plastic using color inkjet printing technology. The implementation of this color inkjet technology is to install a thin rod perpendicular to the conveying direction of the tape at the position before the traditional adhesive tape production line. Adjustment of θ; two thin rods can be set, two nozzles are loaded on one thin rod, which spray red and green respectively, and three nozzles are loaded on the other thin rod, which spray blue, orange and gray r...
Embodiment 2
[0032] For a yellow non-transparent adhesive tape with a width of W=60mm, a winding reel radius of R0=40mm, and a tape thickness of d=80um, the alternating pattern of red and dark blue as shown in Figure 4(a) is used, and the loading method is the electrostatic fixation method of fiber filaments: adding red And dark blue elongated fibers (diameter 0.1mm), add electrostatic charges to the elongated fiber filaments through the electrodes, use the electrostatic effect to fix the elongated fibers on the substrate, and then coat the viscose layer. Realize the line width of oblique stripes is 0.1mm; the distance between oblique stripes is T=50mm, and the inclination angle θ is 15 degrees. Then it can realize no overlap between adjacent layers, no interference between non-adjacent layers, and achieve a good effect of easy identification of the starting point of the tape, and the tape pattern is beautiful and generous.

Embodiment 3
[0036] For the yellow non-transparent adhesive tape with width W=60mm, winding reel radius R0=40mm, tape thickness d=80um: select the pattern as shown in Figure 2 (c) double sinusoidal pattern (hinge type); use the green viscose glue of the shape shown in the pattern The layer is coated on the tape substrate 3 (coating different color adhesive layer method), and then covered with the yellow adhesive layer 1 . The size parameters are: the radius of the winding reel is 40mm, the single period length of the sinusoidal pattern is T=80mm, the height of the sinusoidal peak and valley is 20mm, and the width of the sinusoidal line is 0.2mm. There is basically no overlap between adjacent layers. In this embodiment, because the yellow adhesive layer is yellow, it is made into a non-transparent tape, so the freedom of choice of the size of the sinusoidal pattern is relatively large. The sinusoidal parameters of this embodiment are based on the principle of beautiful appearance, and it is...
