ABSTRACT:
A machine for manufacturing garlands comprising a device for producing a tube from filament-like or strip-like material on two conveyor screws arranged at a distance from one another, which are mounted on one side, driven at the same speed in opposite directions, and have opposite threads by using two parallel pairs of threads, each of said pairs of threads consisting of a core wire or thread extending through a longitudinal bore of said conveyor screws, and an outer wire or thread, and means for twisting said pairs of wire or thread around sections of said winding material, said sections being formed by severing said tube, and with means for drawing off the pairs of wire or thread. The conveyor screws are located at two corners of an imaginary polygon which is symmetrical around the center of the line connecting said corners. Additional conveyor screws are arranged at the remaining corners of said polygon driven at the same speed, so that the number of conveyor screws having one direction of rotation is equal to the number of conveyor screws having an opposite direction of rotation. A cutting device is arranged at each side of the intersecting lines for centrally severing the corresponding half of the tube.
