In a dynamic scale and control method for flat goods transported on their sides, use an input-side first assembly for thickness measurement, a transport device having transport belts arranged on a weighing plate. A control processor starts a length measurement and the driving of the transport belts, and starts a thickness measurement and implement a dynamic weighing process during the transport of a first flat good. A next flat good is supplied to the input of the dynamic scale if a valid weight measurement result is present for the predecessor good, and ejection of the predecessor good or end of the weight measurement occur if a third sensor at the input of a takeoff device of the dynamic scale detects the leading edge of the predecessor good, and a check yields that no valid weight measurement result is present for the predecessor good.

A weigh module (10) for a belt conveyor apparatus is disclosed. Said module (10) comprises a support means, in the form of a plurality of shafts (30) to support a conveyor belt. The module also includes a means to measure rotation of the shaft, which means is preferably a rotary encoder. The shafts are support on elongate supports. In order to determine the mass of material on a conveyor belt, the module includes a load cell engaging a load plate to determine the load on a belt. The shafts are generally cylindrical and can have a plurality of spaced apart rings along the outer surface to engage a conveyor belt.

Automatically adjusting the amount of material delivered by a conveyor belt includes measuring the speed of a drive pulley that drives the conveyor belt and determining the weight of material dispensed onto the conveyor belt from at least one material dispenser on a real-time, ongoing basis. Based at least in part upon such speed and weight measurements, an electronic controller repeatedly adjusts the speed of the conveyor belt by dictating the output of at least one motor that drives the drive pulley.
