Abstract
A weighbelt is conventionally placed in or associated with a production line for weighing material supplied during production. The weighbelt of the invention has a belt 10 which can be lifted by rollers 18 out of contact with a planar support plate 16 without stopping the belt 10. A known mass 24 is then lowered into a cradle 26 to provide a downward force on the plate 16 to calibrate output signals of a strain gauge 22. The strain gauge 22 provides output signals when the belt is supported by the plate 16 indicative of the material loading on the belt 10. The weighbelt can be calibrated without stopping the belt 10 and disrupting production.
