FIELD: process engineering. ^ SUBSTANCE: proposed device comprises two sets of drive elements, arranged at regular intervals so that elements of one set face gaps between elements of another set. Pulsating lengthwise strains in wire are generated per one revolution of the drive thanks to that the base moving lengthwise accommodates the first set of said drive elements and bell crank hinged thereto. Second set of drive elements is arranged on first arm of bell crank. Second arm of said bell crank is furnished with inertia load and arranged across feed direction so that delay of inertia element fitted thereon, when drive elements move in feed direction, makes sets of drive elements approach. Inertia element is arranged on second arm to move and be adjusted thereon. Above described drive of aforesaid sets of drive elements cab reciprocate. ^ EFFECT: simplified design. ^ 3 dwg |
