Tension control system for fiber bundles in filament winding apparatus |
摘要 |
A filament winding apparatus detects that a fiber bundle is likely to break and prevents generation of defective products. The filament winding apparatus applies a prescribed winding tension to the fiber bundle unwound from a fiber bundle feeding package and winds the tension-applied fiber bundle around a mandrel. A tension applying portion applies the winding tension to the fiber bundle at a position that is immediately before a side of the mandrel between the fiber bundle package and the mandrel. A tension sensor detects the tension of the fiber bundle between the fiber bundle feeding package and the tension applying portion. A determination means determines a tension abnormality of the fiber bundle by comparing pre-set reference information with the tension measured value measured by the tension sensor. |
