Sheet press acc. to TAPPI and SCAN

For the de-watering and pressing and hand-sheets produced on sheet formers acc. to TAPPI or SCAN. The sheet press consists of two parallel plates, which are pressed against each other by pneumatic cylinders. Two timers are located on the control module to set the first pressing and second pressing. A channel around the lower plate allows problem free drainage of the liquid pressed out to the rear of the device. Opening the acrylic glass cover activates a safety switch, which immediately stops the pressing process and secures against the unit starting again, to prevent injury.

Test description

The sheet press is used to press sheets that have been manufactured on a sheet machine according to TAPPI and SCAN. The sample (consisting of blotters and hand sheet) is covered with the mirror polished plates, stacked and laid in the sheet press. The first stage is a first pressing of five minutes. Then the mirror polished plates are removed, the hand sheets given new blotters and the second pressing is started. A pressure of 245 kPa is applied for two minutes. Then the paper stack is removed and the hand sheets are ready for drying (e.g. with a speed dryer or drying rings) and conditioning.
