Rolling apparatus of the metal sheet

To provide a rolling device which can accurately detect the rolling direction force acting on the work roll chock. A rolling apparatus for a metal plate having a pair of upper and lower work rolls 1 and 2, a pair of work roll chock 5 and 6 for holding the work rolls 1 and 2, a housing 10 for holding the work roll chock, rolling comprising a rolling direction force measurement devices 21, 22, 23 and 24 for measuring the direction force. Rolling direction force measuring device comprises a plurality of load detection device provided on the housing in the direction of rolling entry side or rolling direction exit side of the work roll chock, a plurality of load detection device, at least two load during rolling of the metal sheet as detecting device is opposed always to the side of each work roll chock are arranged side by side a plurality in the pressing direction. In this case, at least two load detection devices are arranged so as to sandwich the roll axis is power point of the rolling direction force in the pressing direction. .FIELD 7
