FIELD: textile industry, applicable in spinning, roving and other machines. SUBSTANCE: the system has tie-rod and a springs, installed with catches on levers in fixed positions, depending on the necessary load on two pressure rollers on the opposite sides of the machine. The levers have stops limiting the decrease of spring tension, the arrangement of the decrease of spring tension, the arrangement of the stops provides for stability of load at removal of one of the rollers due to restriction of turning of the levers towards the decrease of spring tension. The spring is fixed in the preset points of the levers by the catches with constant values of tension and load. EFFECT: simplified design, enhanced stability of load on pressure rollers at a reduced labour input and saving of power resources. 3 cl, 1 dwg |
