摘要： A single facer machine is disclosed which comprises a first corrugating unit having a pair of upper and lower rolls, a second corrugating unit also having a pair of upper and lower rollw, and a common pressure roll disposed in operative association with both the first corrugating unit and the second corrugating unit. The single facer machine is characterized in that either of the combination of the first corrugating unit and the pressure roll or the combination of the second corrugating unit and the pressure roll is selectively operated to form a single-faced corrugated board.

摘要： A device for continuously measuring the thickness of a foil includes a radiation source opposite a radiation detector, and a movement member which moves the radiation source and detector synchronously in a width-direction of the foil. A signal generator generates a signal indicating a position of a portion of the foil whose thickness is being measured, and a counter having a plurality of integrating channels integrates detection signals output from the detector to generate an integrated count number for each channel. A signal switching member switches each of the plurality of integrating channels of the counter according to signals generated by the signal generator, and a calculator calculates a foil thickness from the integrated counted number for each channel of the counter. This structure allows continuous and precise measurement of the foil's thickness.
