Abstract: The method for electrochemical treatment of goods (1) as section, comprises conveying the goods in transport direction with mutual distance as a gap (15) through continuous flow system by means of rotating or moving transport and/or contact means (3), where the respective contact means is rolled on each goods with reduced flow strength or totally disengaged contact flow or is rolled on end of each good. The nominal current of each contact means is first adjusted and/or enabled towards the complete rolling or sliding on the good and is reduced or deactivated before rolling the good. The method for electrochemical treatment of goods (1) as section, comprises conveying the goods in transport direction with mutual distance as a gap (15) through continuous flow system by means of rotating or moving transport and/or contact means (3), where the respective contact means is rolled on each goods with reduced flow strength or totally disengaged contact flow or is rolled on end of each good. The nominal current of each contact means is first adjusted and/or enabled towards the complete rolling or sliding on the good and is reduced or deactivated before rolling the good. The beginning and the end of each goods and/or the beginning of the end of each space is globally calculated and pursued for each contact position (17) of the continuous plant of a central control system by the data of sensors that are arranged at the inlet area of the continuous plant. The momentary layer of each desired large space and/or each goods in the continuous plant with its respective beginning and ending is measure-technically detected by step-like change of the current or the voltage in or on circuit of the contact means. The spaces globally pursued by the control system is compared with the space individually measured on each contact position and is actualized and/or corrected in control system, where each contact means is individually deactivated during approaching the space through electric switching means and is turned on again towards the space. The treatment current of a rectifier is reduced that is associated to a group of contact means so that the space is reduced on contact means. The current or the voltage is exactly determined in the circuit of the contact means that is measured by the electrical measuring means during reaching the end of the running goods. The treatment current or voltage of the rectifier is controlled on nominal current and/or nominal voltage towards the space during reaching the beginning of the goods by the change of reduced current or voltage in the circuit of the contact means that is measured by the electrical measuring means. A sensor detects at existence of electrically conductive layer on the surface of the goods. An independent claim is included for a method for electrochemical treatment of goods as section.
