Abstract: The powder-rolling device (1) includes: a pair of rolling rolls (2) to attach powder material (Y) to a sheet-shaped base material (X) by pressure; a preliminary press roll (8) to press the powder material (Y) to a circumferential surface of a rolling roll (2) before the powder material (Y) is attached to the base material (X) by pressure; and a support device (10) supporting the preliminary press roll (8) movable, so that a load applied to the preliminary press roll (8) becomes equal to a set value which has been set beforehand.

Abstract: The invention provides a production management system and a production management method which are applied to an optical display device production system which can more precisely carry out a production management. A memory stores a panel information allocated per an optical display unit, and a roll information including a positional information of optical films in a material roll before the optical films bonded to the optical display unit are cut so as to coordinate. A position in the material roll before the optical films bonded to the optical display unit are cut is specified based on the panel information corresponding to the optical display unit of the optical display device determined by an inspecting apparatus that a defect exists, and the roll information coordinated to the panel information. If it is possible to recognize what position in what material roll the defect exists, as mentioned above, it is possible to carry out a production management more precisely.
