Technical Field

The invention relates to production equipment of clothing accessories, in particular to a spiral forming device for a composite strip of plastic and cloth.

Background

A composite strip of plastic and cloth is formed by extruding molten plastic to a cloth belt, folding and folding the left side and the right side of the cloth belt to wrap the plastic, and cooling. The composite strip can be applied to the fields of clothes, cloth decoration and the like, and can be used as a substitute for some supports. For different applications, the composite strip may have different shapes, such as a steel ring on a brassiere product, and may be replaced with the composite strip described above, which is required to form an arc of a predetermined arc length. In view of production efficiency, the composite strip is generally produced continuously by the composite strip production equipment, and how to perform arc forming on the continuous strip composite strip is a difficulty in manufacturing the arc composite strip.
