FIELD: textile, paper. ^ SUBSTANCE: method refers to manufacture of bond paper protected from forgery, using polymer thread with figured edge as a protective element. The thread consists of central core and side elements shaped as wings. The polymer metallised thread with figured edge is implemented into the paper during the process of its manufacturing in the mold of the papermaking machine. Then follows dehumidification of the product along with layer forming and its pressurising. The thread is strained during implementing into paper. The thread strain provides creation of fibers on the surface of central core in the wings area. This provides voluminosity of the protective element. ^ EFFECT: bond paper protection enhancement. ^ 9 cl, 3 dwg
