Abstract: Process for the manufacturing of wood chips as raw material in the production of mechanical pulp in order to reduce the energy consumption in the production of pulp, characterized in that the wood fibres, including the summerwood fibres, are irreversibly deformed across the grain, i.e. in a direction perpendicular to the longitudinal axis of the fibres. Preferably this is done through mechanical treatment with one or several tools, arranged so that the forces created in the treatment act in a direction substantially perpendicular to the longitudinal axis of the fibres.
