Zusammenfassung:	A first exemplary aspect is a press roll apparatus including: a first roll and a second roll configured to hold a workpiece therebetween to press the workpiece; a mobile unit configured to move the second roll; a detection unit configured to be able to detect a load that acts between the first and the second rolls; and a control unit configured to control the mobile unit. The control unit moves the second roll in a direction in which the second roll approaches the first roll in a state in which the workpiece is not held between the first and the second rolls, and sets a position of the second roll where the load detected by the detection unit has become equal to or greater than a predetermined value as an origin position.
