ABSTRACT:
A continuous stream of tobacco leaves is equalized on the endless belt of a weighing device which receives an unequalized stream from a carded conveyor forming part of a tobacco feeding device. The belt is pivotable with an arm of the weighing device in response to changes in the weight of successive increments of tobacco thereon. Such changes in weight are ascertained by a potentiometer and signals denoting the weight are transmitted to a function generator by way of an adding circuit as well as to a multiplying circuit which further receives signals denoting the speed of successive increments on the belt. Signals which are transmitted by the multiplying circuit are used to regulate the speed of the belt so that the product of signals denoting the weight and of corresponding signals denoting the speed of successive increments of tobacco on the belt remains constant. The speed of the conveyor in the feeding device is regulated in response to signals which are transmitted by the function generator and denote the extent and duration of deviation of changes of the signals denoting the weight of successive increments from a given value. Signals denoting the speed of the conveyor can be modified in dependency on signals denoting the speed and/or weight of successive increments to regulate the operation of one or more devices for the processing of tobacco in the equalized stream which leaves the belt of the weighing device.
