The present invention relates to a continuous roll-to-roll material joining method, and more particularly to a joining method which enables a roll manufacturing apparatus to smoothly join old materials and stock materials to improve productivity.

In the conventional technology, in general, a roll manufacturing equipment (such as a coating line) processes a whole roll of material (such as a plastic film) through a process (such as a plastic film) and then winds it into a roll. Finished product (such as tape). However, when the old material in the production process will be used, the roll manufacturing equipment should be shut down first, and the edges of the old material A and the material B are joined by the adhesive material C or other means, as shown in Fig. 1. . Such a conventional material joining method is time consuming and time consuming, and further, due to the bonding method using the adhesive material C, the joint quality is poor, for example, the joint thickness is increased and the edge is lifted, resulting in the inner joint. The finished product cannot be used as a normal product, so the productivity is low and it is not ideal.

In view of this, the inventors have continuously researched, experimented, and improved a continuous roll-to-roll material joining method, which makes the joining of the old material and the preparation of the roll manufacturing equipment more convenient and more efficient, and the joining method can be used.
