FIELD: textile, paper.
SUBSTANCE: device includes a flat lattice forming device, an apparatus to feed a paper mass to a forming lattice, a thread-feeding device and a facility to create open sections on the protective thread in the form of a system of nozzles connected to a line of water supply and with an electronic device to adjust head and time of water supply to nozzles. The facility to create open areas on a protective thread is a system of two parallel rows of nozzles arranged so that the first row of nozzles along with the motion of the paper web ensures water supply at the angle of 85-110° to the paper web, and the second row of nozzles ensures water supply at the angle of 100-130° to the paper web.
EFFECT: invention makes it possible to improve quality of produce by increasing of stability in process of making open areas on a protective thread during paper making.
