    Hot melt polyester adhesive tape and method for its preparation Technical field of the invention
    The present invention relates to a hot melt polyester adhesive tape and its method of preparation.
    State of the art
    The thin wires inside the market using the data lines are wrapped with several finer wires. These thinner wires are compactly wound apart by only a very thin layer of insulation or wire. If the local casing is machined in case of negligence during use, it is easy to cause the problem for the whole son even to be blown. In order to avoid the above problems, when producing these yarns, it is necessary to wrap a layer of protective film by the finer threads. This type of protective film is usually the insulation wire. When producing this type of film, the rolled disc diameter is large enough to cause inconvenience to production. At the same time, it is necessary to prepare the rewinding machine to process the winding of the badly formed protective film or rewind this winding film to wind in a portable type.
