Abstract
Tubular textile fabric passes through a singeing apparatus preferably vertically upwardly. A guide path including a circular spreader guides the tubular fabric past gas operated singeing nozzles which are position adjustable in parallel to the longitudinal travel direction and radially thereto. The circular spreader forms a conical zone in the tubular fabric and the singeing nozzles are located around the conical zone so that an axial position adjustment of the nozzles changes the spacing between the nozzles and the fabric and a radial adjustment of the nozzles centers the nozzles relative to the fabric. The conical zone may taper in a direction opposite to the travel direction or in the travel direction of the fabric. The taper and its direction is determined by the diameter and the location of fabric guide rings forming part of the spreader. Cooling devices are located downstream of the singeing nozzles as viewed in the travel direction of the fabric.
