Abstract: A method for manufacturing adhesive tape that pattern and mark are easily formed thereon which includes the steps of placing a felted surface of a felt portion on the bearing portion of a lower mold, alter closing the upper mold, injecting a plastic material via high pressure to merge to the back side of the felted surface, thereby the plastic board can be integrally combined wit the back side of the felted surface to obtain the best combined strength. The plastic board can be formed with specific patterns or marks as desired, such that the adhesive tape can have a hard strip to make it easier for the user to detach, even if the user is wearing heavy gloves. In addition, a logo or mark can be formed on the adhesive tape to enhance the aesthetic effect.
