Abstract
A warp creel for a beam warping machine is disclosed which comprises a number of bobbins arranged in horizontal and vertical rows, a thread or yarn or the like being continuously withdrawn from such bobbins. At the region of a predetermined portion or section of the warp creel, at the rear region of such creel, there extend a multiplicity of rods which rise vertically over all of the levels or storeys of the warp creel and impart a deflection or turning motion to the threads of at least one vertical bobbin row. The rods are displaceably supported between a preparatory position orienting the individual rods in front of the thread tensioning and monitoring devices of the related bobbin rows and a bunched together or clustered terminal position located towards the creel delivery or outfeed side and serving to separate the threads. Due to these measures it is possible to adequately separate the threads practically without any additional friction, and the accessibility for drawing-in the threads during bobbin change operations or thread rupture is completely maintained.
