Abstract: A texturizing machine for false-twist crimping of synthetic yarns having a plurality of work stations at each of which yarn is drawn by feed rolls from supply bobbins and guided successively through a heating device, a cooling device and a texturizing unit to a group of superjacent bobbin winding units, with the bobbin winding unit groups being arranged in longitudinal succession along the length of the machine. A pair of opposed spaced longitudinaly extending support frames define an operator service passageway therebetween. The heating devices, cooling devices and texturizing units are disposed adjacent the passageway with the yarn being guided over the passageway. The bobbin winding units are mounted on the opposed frames on both sides of the passageway with the groups of bobbin winding units alternately mounted successively on opposite frames longitudinally of the machine with the yarns of successive bobbin winding unit groups being guided in opposite directions over the passageway.
