    摘要： In a single facer, the roll for applying pressure to the liner web forcing it against the glue containing flute tips of the corrugated web is moved between operating and retracted positions by double acting power cylinder means operated by relatively high pressure fluid. When the pressure roll reaches its operating position, it operates a control valve to automatically control application of an opposing pressure, at lower than said high pressure, to the double acting cylinder means so that the net force maintaining the pressure roll in its operating position is derived from the net value of the high and opposing pressures.

    摘要： A gluing unit for inside and outside glue laps is constructed with a single glue wheel on a frame mounted for vertical movement to selectively position the glue wheel above and below a sheet feeding path. The frame is also pivotable 180* about a vertical axis, so that the peripheral portion of the glue wheel which engages the sheet material moves in the same direction as the sheet material regardless of whether the glue wheel is applying glue to the upper or lower surface of the sheet. A single doctor means and a single glue nozzle, directing glue against the glue wheel periphery, are provided together with a single glue outlet in the movable frame.
