Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cord fabric manufacturing, in particular to a full-width anti-folding tool for cord fabric impregnation. BACKGROUND

[0002] Tire cord fabric is a special material, mainly used in the inner layer (cord layer) in tire manufacturing. It is a composite material made of fiber and rubber mixture, usually made of nylon, polyester, aramid, polyester, etc. Tire cord fabric usually has excellent properties such as high strength, high durability, high elasticity and corrosion resistance, and can withstand the effects of high pressure, high temperature and high speed in vehicle driving under extreme conditions.

[0003] In the production process of cord fabric, there is a large difference between the width of the normal cord fabric and the width of the connecting joint between the guide fabric during start-up, and the width of the connecting joint between different varieties and specifications of cord fabric roll. In the process of sewing machine sewing, the wider fabric head needs to be folded and connected with the narrower fabric head. The width of the connecting joint after connection is consistent with the width of the narrower fabric head. However, this often causes the warp of the wider cord fabric to fold with the folded fabric head after the joint is completed. If not handled in time, the entire roll will be folded, resulting in waste fabric. Even if handled in time, at least 50-100 meters of waste fabric will be produced.

[0004] At present, the following treatment methods are commonly used during elongation. The width of the wider fabric head is uniformly folded and distributed in multiple times during the joint process by using the expander on the tension frame and manual assistance. After the joint, the operator tracks the fabric head and uses a wooden rod to separate the folded part to the two sides, so that the folded part is separated. Since the expander is in a fixed position, the cord fabric passes through the oven for high-temperature treatment between the expanders, the weft yarn shrinks due to heat, and the folding is more serious. The expander cannot fundamentally solve the folding problem. After the folded part is expanded by the expander, there is an obvious thinning of the road, i.e. the phenomenon of uneven arrangement of warp. Since the speed is relatively fast during the production process of cord fabric, this operation has safety risks and requires high operating skills. UTILITY MODEL CONTENTS
