Two intermittently and oscillating driven feeding rollers (2; 3) are adapted to feed a strip-shaped workpiece (63). The bottom feeding roller (2) is supported in the frame (1) of the feeding device. The upper feeding roller (3) is supported in a rocker (30). The movement of the rocker (30) is controlled by a control disk (64) through a lever and a rod arrangement (40). The rocker (30) rests at one end (33) via a pressure spring (39) against the frame (1). At the opposite end (34) the rocker (30) rest against the frame (1) via a further pressure spring (36). The rocker (30) is supported in an overhung state on a cantilever which consists of a sleeve (70), a arm (71) projecting laterally from the sleeve (70) and a shaft (72) held clamped in the arm (71). The clamping bar (46) is firmly mounted to the shaft (72).
