Rigid and Flexible Rapier Systems
topic
Rigid rapier systems use a solid rod or tube that extends from the loom frame into the shed, with a gripper head at the tip that holds the weft yarn during insertion and releases it at transfer or selvedge, operating across narrow to medium fabric widths up to 220 centimetres where the rigid rod length is mechanically feasible, while flexible rapier systems use a flat steel band that can be wound onto a storage wheel at the loom side, enabling wider fabric widths up to 540 centimetres by accommodating the longer rapier length required on a compact wheel.
Role
Represents two distinct engineering solutions to the rapier length management challenge that determines the maximum practical fabric width, with rigid rapiers being mechanically simpler and providing more positive yarn control but limited in width by rod deflection at length, while flexible rapier bands enable wide-width weaving by storing the excess band length on a compact wheel at the cost of the more complex band guide and tension management required for band straightness during shed traversal.
