Device for controlling a flexible rapier and shuttle loom including at least one such device

摘要

Device for controlling a flexible lance for a weaving loom comprises a toothed drive wheel that engages with a pinion; a toothed part that cooperates with the pinion to rotate the toothed wheel; a crown wheel that executes one turn per weft pick to drive the toothed part by means of a connecting rod linked to the crown wheel and to the component with the toothed part. The rotational axis of the crown wheel is located between upper and lower parts of the tooth structure of the toothed wheel. Device for controlling a flexible lance for a weaving loom comprises a toothed drive wheel whose rotational axis is parallel to the warp axis and which engages with a pinion; a toothed part that cooperates with the pinion to rotate the toothed wheel; a crown wheel that executes one turn per weft pick about an axis perpendicular to the rotational axis of the toothed wheel to drive the toothed part by means of a connecting rod linked to the crown wheel and to the component with the toothed part about two axes parallel to the weft insertion axis. The rotational axis of the crown wheel is located between upper and lower parts of the tooth structure of the toothed wheel. An independent claim is also included for a weaving loom equipped with a control device as above.
