Abstract:
1. A sheet material supplying device for use with a processing device that draws out a long sheet material from a raw-cloth roll, formed by winding the sheet material into a roll, by a drawing-out mechanism, and that processes the sheet material at a processing section, the sheet material supplying device rotatably supporting the raw-cloth roll with respect to a frame, the sheet material supplying device comprising: a tension detection device that detects tensions at both end portions of the unprocessed sheet material in a widthwise direction of the sheet material; an engaging roller located upstream of the processing section in a path of the sheet material that is drawn out from the raw-cloth roll in an upstream side towards the processing section in a downstream side, the engaging roller engaging at least a portion of the sheet material; a supporting mechanism that supports both end portions of the engaging roller and that is displaceably supported with respect to the frame such that an axis of the engaging roller is tiltable in a direction that crosses a sheet surface of the sheet material with which the engaging roller engages; an actuator that is connected to the supporting mechanism and that displaces the supporting mechanism; and a drive control device that controls driving of the actuator on the basis of the tensions detected by the tension detection device.
