Abstract
A thread delivery device, particularly for use with a texturing device, is described wherein an endless belt runs over two freely mounted rollers on a pivotable support. In the operative position of the support, the belt between the rollers contacts a power driven cylinder over a predetermined wrap angle. In this position, an adjustable abutment keeps a spring loaded belt guide element out of contact with the belt. However, when the support is swung to an inoperative position in which the belt is withdrawn from the driving cylinder, the abutment ceases to be effective so that the guide element, which is carried by a pivotally mounted arm to which the spring is applied, engages the belt and takes up the slack that would otherwise appear due to the elimination of the wrap on the cylinder. The spring may be connected either to the support or to a fixed part.
