ABSTRACT:
A cylindrical tube is inclined from the vertical below a sliver guide, the bottom end of the tube being mounted on a supporting element, and the upper part being accommodated in a bearing, the outer race of which is located in a horizontal plate. The horizontal plate has a gyratory motion imparted to it through two crankshafts, such that the tube would undergo a nutational movement. To improve the distribution of the sliver, the axis of the cycloidal loops of sliver passing from the tube is shifted by journaling the crankshafts on a second horizontal plate to which a gyratory movement is imparted by a second pair of crankshafts. The first pair of crankshafts is driven more slowly than the second pair.
