摘要：A device for processing a concrete layer by water jets, comprising a jet tube ona carriage moveable to and fro along a guide. The jet tube is pivoted in planessubstantially parallel to the guide and oscillates in planes making an angle with theguide. The jet tube is inclined in one direction along the extension of the guide during themovement of the carriage along the guide, and a control unit ensures that pivoting of thejet tube with an angular velocity leading to movement of a nozzle of the jet tube alongthe guide with a velocity substantially equal to the velocity of the carriage is initiated atthe same time as the carriage is stopped in an end position, and the control unit startsthe movement of the carriage in an opposite direction when the jet tube has finished itspivoting movement.
