Double twisting spindle with a pneumatically operated threading device |
摘要 |
A double twisting spindle is equipped with a pneumatically operated threading device. An injector nozzle is provided in the spindle rotor, an air stream through which nozzle sucks a thread into a hollow spindle axle and moves the thread through a thread channel in the storage plate. A compressed-air supply device is arranged below the spindle rotor for supplying compressed air to a central connecting channel provided in the spindle rotor and in communication with the injector nozzle. A common operating lever is provided which first operates a spindle brake and then opens a valve of the compressed-air supply device. The connecting channel has at its open lower end a funnel-shaped enlargement. The compressed-air supply device is stationary and has a blow nozzle which is fixedly arranged a small distance from the lower end of the spindle rotor and has an outlet opening which is coaxial with the funnel-shaped portion, the diameter of the outlet opening being smaller than the inlet diameter of the funnel-shaped portion.
