APPARATUS FOR STOPPING FEEDING OF ROVING INTO DRAWER OF WEAVING MACHINE UPON RUPTURE OF YARN Russian patent published in 2006 - IPC D01H13/18 

FIELD: textile industry.

SUBSTANCE: apparatus has yarn checking probe connected to pawl and mounted on bracket pin for periodic contacting with yarn during contacting of probe through pawl with cam freely put on feeding cylinder, controlling lever connected to pawl, and column freely mounted on feeding cylinder. Torsion spring is located within cylindrical bore of column, one end of said spring being fixed within column and other end being fixed within cam. Inner diameter of torsion spring in its free state is smaller than diameter of feeding cylinder for rotating of column and cam in conjunction with feeding cylinder. Cam for controlling of yarn rupture probe is equipped with protrusion which abuts against pawl upon rupture of yarn, said cam rotating relative to column. Axial movement of column, cam and torsion spring over feeding cylinder is restricted by stop rings.

EFFECT: simplified construction of apparatus due to absence therein of parts having complicated profiled slots.
