Chromosphere fibrils oriented along the neutral line in close vicinity of solar filaments create typical characteristics of the filament channel. From systematic Doppler velocities measurements made at Kanzelhöhe Solar Observatory with the Magneto Optic Filter (MOF) we derived the horizontal velocity fields. Horizontal velocities were determined in areas strongly connected with filament channels and also outside these regions. Close along the filament axis in the direction of the polarity inversion line a strong shear of the mean horizontal velocities was detected.
