Abstract
The invention relates to apparatus for inflating a continuously moving length of tubular material, in which the nozzle tube is rotatable and an arrangement is provided which locks the nozzle tube in an angular position in which the nozzle is in contact with the length of material during the discharge of gas from the nozzle. Such apparatus is distinguished during the greater part of the production time by a considerable reduction in the friction between the length of material and the nozzle tube.
