ABSTRACT:
A nozzle arrangement in a blow box of a paper machine, comprising one or several nozzles (22a, 22b) placed in connection with the blow box (20) or pipe, through which nozzles a blowing of air can be applied to a moving member in a paper machine placed in their proximity, such as a wire, drying cylinder, guide roll, felt, or the equivalent. The blow box (20) and its nozzles (20a, 20b) are at a certain operational safety distance (C) from the moving member. In connection with the nozzle slots of the nozzles (22a, 22b) or nozzle, a respective nozzle flap (24a, 24b) pivotable around a respective transverse hinge shaft (P) is hinged. The nozzle flaps (24a, 24b) respectively guide the blowing of air (F.sub.a, F.sub.b) to the desired object and if necessary maintain a required difference in pressure. The nozzle flaps (24a, 24b) are hinged in such a way that, in their normal operating position, the outer edge of the respective flap is at a distance considerably shorter than the required operational safety distance from the moving member (10, 12), but the nozzle flaps (24a, 24b) can pivot to the required safety distance when a paper clod or some other obstacle passes by.
