Determining your Web Feed Rate!
Do you know your web feed rate? We can help you determine it. In this paper, a measurement method is described and demonstrated for accurately measuring nip roller feed rates.
- Data is presented for asymmetrical nip systems consisting of a rubber-covered nip roller loaded against a metal roller
- Results are shown for a conventional nip roller covering and a second nip roller covering engineered with the ability to control nip roller feed rate while retaining desirable nip pressure characteristics
- Results from a troughing and wrinkling study using two pairs of end-loaded symmetric nip rollers of each design are also presented
- Results are used to compare and contrast the performance of nip rollers systems where differences in nip roller feed rate significantly alters system behavior
