A catalogue of integrated pulse profiles of 56 pulsars with observations at 102, 230, 408, 610, 1400, 4700, and 10500 MHz is presented. The profiles are aligned in time (phase) so that direct comparisons of changes in the profile shape and component composition can be made. Smearing due to interstellar scattering at low frequencies for pulsars with large dispersion measures was removed by means of a special "descattering" method (Kuzmin & Izvekova 1993).

Most pulsars show good alignment over the whole frequency range 0.1 to 10.5 GHz, if the dispersion measure is corrected slightly in comparison to the published value. We confirm a non-dispersive time shift of the integrated profile for PSR 0809+74 as presented by Bartel et al. (1981), Davies et al. (1984), and Kuzmin et al. (1986).

This paper presents the data in form of a catalogue of time aligned profiles. A detailed analysis of the change of pulse structure with frequency by means of a decomposition of the average pulse shape into gaussian components will be presented in a forthcoming paper.
