る。Prior art and problems When transporting rubber compounds, a container assembled from plywood or wood is sometimes used, but it is necessary to prevent the fibers from fuzzing at the edges of the plywood, or to use small split boards as the wood. Single-sided adhesive tape is sometimes applied to seal the joints of the boards. In such a case, the adhesive tape will come into contact with the rubber compound with a pressure equivalent to the compound's own weight, and even if the contact surface of the adhesive tape is the support surface, the pressure sensitivity of the rubber compound and the large contact The contact surfaces eventually become strongly bonded due to pressure and the like.
このため、コンテナーからゴムコンパウンドを
取出すときに、粘着テープがゴムコンパウンドに
接着したままで取出されることがある。 Therefore, when the rubber compound is removed from the container, the adhesive tape may remain adhered to the rubber compound.

叙上の通りゴムコンパウンドに強力に接着してい
るので、その剥離除去は至難である。 Furthermore, the support for the above-mentioned adhesive tape includes polyethylene laminate paper, polypropylene film,
If a polyethylene-polypropylene blend film is used and the rubber compound is kneaded with the adhesive tape still attached, the unmelted adhesive tape support will be mixed into the rubber molded product as foreign matter. It is essential to completely remove the adhesive tape, as this will lead to a decrease in the strength of the molded product. However, as mentioned above, this adhesive tape strongly adheres to the rubber compound, so it is extremely difficult to peel and remove it.
考案の目的
本考案の目的は、ゴムコンパウンドから除去せ

ことにある。Purpose of the invention The purpose of the invention is to provide an adhesive tape for rubber compounds that allows the rubber compound to be kneaded directly without being removed from the rubber compound.

を特徴とするものである。Structure of the invention The adhesive tape for rubber compounds according to the invention uses a thermoplastic plastic film that can be melted during kneading of the rubber compound as a support for the adhesive tape that is used in contact with the rubber compound when the rubber compound is conveyed. It is characterized by being constructed as follows.
実施例の説明 以下、図面により本考案を説明する。Description of examples The present invention will be explained below with reference to the drawings.

る。 In the figure, reference numeral 1 denotes a support made of thermoplastic plastic film, which can be melted during kneading of the rubber compound. for example,
A low-density polyethylene film, or a film containing low-density polyethylene as a main component to which high-density polyethylene or a modified product thereof or polypropylene is added within a range whose softening point does not exceed 130°C can be used.

ともできる。 As mentioned above, the adhesive tape according to the present invention is used for covering the ends of plywood boards and for sealing between the small boards in a rubber compound container made from plywood boards and small boards. Furthermore, when the rubber compound is transported in a folded sheet form, it can also be used as a label sheet that is attached to the surface.

ができる。 However, when taking out the rubber compound from the rubber container, even if the adhesive tape is still attached to the rubber compound, when molding the rubber compound, anti-aging agents, fillers, etc. are added and the rubber compound is mixed with a Banbury mixer or kneader. Since the kneading temperature during kneading is 150° to 180°C, the adhesive tape is melted and dispersed in the rubber compound. Therefore, no foreign matter remains in the molded product, and a molded product with sufficient strength can be obtained.
