Technical Field
[0001] The utility model relates to the technical field of adhesive tape machinery, in particular to an adhesive base tape flattening and extending device. Background Art
[0002] Adhesive tape is made of paper, cloth, or plastic as the base material, and then glue is evenly applied to the aforementioned base material to produce adhesive tape. In this way, adhesive tape is divided into paper tape, cloth tape, and plastic tape. Conventional adhesive tapes with plastic as the base material generally use acrylic adhesives, silicone adhesives, rubber adhesives, or PU adhesives as adhesives, but these adhesives are basically difficult to effectively adhere to silicone rubber-like low surface energy objects. Even if modified silicone adhesives are used to adhere silicone rubber, very thick silicone adhesives are required. The thickness of the base material is thicker than that of paper and cloth base materials, and the ductility is greater, resulting in uneven application of the glue liquid, and a series of problems such as a thick adhesive tape.
