A base material processing apparatus includes a transport mechanism, a force detection part, a meandering prediction part, a processing part, and a controller. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path aimed by a plurality of rollers of the transport mechanism. The force detection part detects a force applied to a sensing roller in an axial direction of a rotation shaft thereof, the sensing roller being at least one of the plurality of rollers. The controller predicts the meandering state of the base material to output meandering prediction information, based on the force applied to the sensing roller in the axial direction of the rotation shaft thereof. The meandering prediction part corrects the widthwise position of the base material relative to the processing part, based on the meandering prediction information. Thus, the base material processing apparatus is capable of sensing the meandering state of the base material through the use of the existing rollers of the transport mechanism in the processing part, and is capable of correcting the widthwise position of the base material relative to the processing part.

A method for manufacturing an electrode assembly includes a first combination step of combining a first electrode with an upper portion of a first separator to form a first combination, and a second combination step of combining the first combination so that a second electrode faces the first electrode with the first separator therebetween after the second electrode is stacked on a second separator, wherein the first combination step comprises a first electrode cutting process of moving the first electrode in an X-axis direction that is a progress direction to cut the first electrode to a predetermined size, a first electrode transfer process of transferring the cut first electrode, a first first-electrode position detection process of measuring a Y-axis position of the first electrode, a first separator meandering correction process of moving the first separator, a first stacking process of stacking the first electrode on the first separator.

A metal strip is guided on transportation rollers through a strip treatment installation. The installation includes successive strip movement control devices along a transportation direction. The strip movement control devices detect and adjust the position of the strip transverse to the transportation direction. A method for operating the installation includes: detecting the position of the strip transverse to the transportation direction by sensors of upstream strip movement control devices; identifying properties that influence the position of the strip transverse to the transportation direction of the strip by the sensors; assigning the identified properties of the strip to corresponding points or segments of the strip; and proactively adjusting the position of the strip transverse to the transportation direction at downstream strip movement control devices based on the properties for the corresponding points or segments of the strip identified by the upstream strip movement control devices.

A roll medium transport apparatus includes a feed roll medium support unit that feeds a roll medium, a takeup roll medium support unit that winds up the roll medium that has been fed, a position acquiring unit that acquires a position of a side end portion of the roll medium that is to be fed, a radiating unit capable of radiating light with a position of the side end portion being used as a reference point. The radiating unit is held by the feed roll medium support unit and allows the light to be radiated to a takeup roll that winds up the roll medium.
