ABSTRACT:
A device for retransporting a thread end of a take-up coil to a withdrawal tube of a spinning machine, includes a two-armed suction tube with a suction nozzle, the suction tube being pivotally mounted and being formed with a bend in a plane wherein it is pivotable, the suction tube having a longitudinally extending slot formed on the inside of the bend for passage of a thread therethrough and into the suction tube under suction, the suction tube having a suction-air flow path extending from the suction nozzle at an end of one of the suction-tube arms through the one suction-tube arm and through the other of the suction-tube arms to the end of the other suction-tube arm and therefrom through an air guidance part to a union for a negative-pressure suction source.
