Component of equipment used for fiber web production line

The utility model relates to a component of equipment used for a fiber web production line. The component comprises a scraping rod or scraping knife (21). The component particularly relates to a scraping rod seat or a scraping knife retainer or a retainer component of the scraping rod or scraping knife (21) of the equipment used for coating or gluing fiber webs, particularly paper or paperboard webs. The component comprises a retainer (25); in the retainer, the scraping rod or scraping knife (21) is supported in the front side of the retainer (25), and the component is provided with a loading device (24). The component further comprises a sensor, particularly a piezoelectric sensor (10), positioned between the scraping rod or scraping knife (21) and the loading device (24), and the sensor is used for partially measuring the loading pressure of the scraping rod or scraping knife (21). The dose distribution of a coating or gluing medium through the scraping rod or scraping knife is improved, partial peak value
