ABSTRACT:
A continuously running, band-formed or mat-formed material, such as mineral wool, is weighed continuously at a given point, and the sensed weight is used to control the speed of a conveyor arrangement along which the band of material is running. The material is supported and transported along a first driven conveyor and onto a second driven conveyor spaced a short distance from the discharge end of the first conveyor. The first and second conveyors are oriented to form an upwardly concave obtuse angle such that the band of material deforms and bends through an upwardly concave obtuse angle as it passes from the first conveyor to the second conveyor. The band of material is continuously weighed as it passes between the first and second conveyors by passing the deformed and bent band onto and along a third non-driven idler conveyor located between the first and second conveyors and arranged to continuously sense the weight of the band passing therealong. The first and second conveyors are driven at equal speeds, but the speeds are varied in response to weight changes sensed by the third conveyor means. The third conveyor means may be in the form of a roller mounted in the space between the first and second conveyors.
