DEVICE FOR APPLICATION OF POLYMER MELTS TO EDGES OF TEXTILE SHEETS

摘要

FIELD: devices for treatment of edges, mainly, of technical sheets; applicable in application of melts of polymers and polymer compositions to edges of textile sheets and articles, particular, edges of woven synthetic screens of paper-making machines. SUBSTANCE: melt supplying unit is made in form of two cylinders with pistons and connected with die head by means of detachable joint. Drive is made in form of crank mechanism and toothed clutch connected with it by means of gearing. Crank mechanism is connected with piston rods. Toothed clutch is installed for interaction with sheet. Gearing gear ratio is calculated by the formula given in the invention description. EFFECT: higher efficiency. 3 dwg
