Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment technical field, concretely relates to a production equipment of composite non -woven fabric self -adhesive bandage. BACKGROUND

[0002] The base material of the self-adhesive elastic bandage is usually non-woven fabric or other fabric with certain elasticity. However, due to the poor elasticity and self-adhesion of non-woven fabric itself, most self-adhesive elastic bandages with non-woven fabric as the base material are made by weaving spandex in the non-woven fabric base material to make the non-woven fabric base material have elastic effect, and then coating adhesive fiber agent to make the non-woven fabric base material have self-adhesion, so as to obtain a bandage with self-adhesion and elasticity. However, the self-adhesion and elasticity of such self-adhesive elastic bandage mainly come from the additional materials, for example, the non-woven fabric base material is made elastic by adding spandex in the non-woven fabric base material, and the non-woven fabric base material is made adhesive by coating adhesive fiber agent on the non-woven fabric. Therefore, the process is relatively complex, resulting in relatively high cost of materials, equipment and process. In addition, the inner and outer sprayed dressings and adhesives are difficult to be synchronized during the production of the existing self-adhesive bandage, and the shaping effect is not good.

[0003] In order to solve the problems existing in the prior art, people have carried out long-term exploration and put forward various kinds of solutions.
