FABRIC BROADENING APPARATUS Russian patent published in 2001 - IPC

FIELD: textile industry. SUBSTANCE: fabric broadening apparatus has chains defining entrance field with divergent chain guides at fabric broadening station providing broadening of fabric to required width. Guides are diverging in curved lines in accordance with parabola law characterizing changing of fabric broadening force. Maximum steep curvature path is formed at head end of broadening station, where fabric exercises low broadening force, and minimum steep curvature path is formed at tail end of broadening station. Such construction of guides provides uniform changing of fabric broadening force and minimum length of entrance field in high-speed broadening units. EFFECT: simplified construction and increased efficiency. 1 dwg
