Adjustable wire guide ceramic positions keep the filament bundle vertical in polyester FDY, reducing lousiness and loose loop yarns.

A wire-core thermoplastic shell enables FDM heatsinks with better heat dissipation while cutting metal part cost and delivery delays.

Combines FDM thermoplastic shells with flexible-mantled conductive wires to improve heat dissipation without costly metal printing.

A P(VDF-TrFE) formulation with surfactant and adhesion promoter creates uniform 5–100 μm coatings without high-voltage electrowetting.

Aldehyde treatment adds reactive groups to PAEK surfaces, enabling covalent coatings that support cell adhesion and osseointegration.

A cylindrical roller cover minimizes air disturbance around a yarn guide roller, reducing power consumption by stabilizing airflow.

A fiber width adjustment device uses a conical guiding path to constrain tape material width during feeding.

A fiber guide uses anisotropic surface roughness to enable smooth sliding and reduce contact area.

Detecting splice positions allows a fiber splitting means to stop thrusting, preventing breakage during continuous conveyance.

Internal Joule heating eliminates external heat losses and prevents localized fiber damage during sizing removal.

An electrolyte bath and PTFE blades split high filament count carbon fiber tows, preventing tangling and tearing while maintaining uniform mass distribution.
