    • Sheet handling apparatus comprises an input hopper (2); one or more output hoppers (105); a transport system (15, 19, 24) for conveying sheets singly from the input hopper to the or one of the output hoppers; and a detection system (50) passed which the sheets are conveyed for detecting one or more characteristics of the sheets. A microphone (220) is arranged to respond to noise produced by a sheet as it is being bent around a roller (19) of the transport system. A control system is connected to the detection system (50) for controlling operation of the transport system. The roller (19) has a substantially constant radius so that the curvature imparted to the sheet by the roller is substantially constant along the dimension of the sheet parallel to the axis of the roller, the control system being connected to the microphone (220) to determine the stiffness of the sheet.
    • 纸张处理装置包括输入料斗(2); 一个或多个输出料斗(105); 用于将片材单独地从输入料斗输送到输出料斗或其中一个输送料斗的运输系统(15,19,24); 以及检测系统(50),通过该检测系统,纸张被输送以检测纸张的一个或多个特性。 麦克风(220)布置成响应于当纸张绕传送系统的辊(19)弯曲时产生的噪声。 控制系统连接到检测系统(50),用于控制运输系统的运行。 辊(19)具有基本上恒定的半径,使得通过辊施加到片材的曲率沿着平行于辊的轴线的片材的尺寸基本上恒定,该控制系统连接到麦克风(220)至 确定片材的刚度。
