TAPPI TIP0404

The objective of this procedure is to provide guidelines for press testing under production conditions. The following procedures are most appropriate for straight through presses. Other types of presses such as bi-nip or tri-nip are difficult to sample, particularly on wide machines. Each individual press can be evaluated by subtracting the exiting water from the entering water. The moisture profile across the machine is easily visualized by graphing data at each press position. Detailed analysis of press operation is possible when a history of test data is developed.
