Description

Technical Field

[0001] The invention relates to the technical field of warp yarn regulating devices, in particular to an automatic warp letting-off device for producing steel skeleton composite tubes. Background Art

[0002] The tensile force exerted on the warp threads inside the steel skeleton composite pipe is crucial to the stability of product size production. However, the existing warp feeding mechanism only realizes the transmission of the warp threads, and does not consider the influence of the tensile force exerted on the warp threads. It is impossible to adjust the tension of the warp threads according to production conditions. At the same time, during the production process, the resistance exerted on the warp threads at different positions is also different. Extruding warp threads with different tensile forces will cause certain bending deformation of the composite pipe used in production, affecting product quality and being unfavorable for production and processing. Summary of the Invention
