Abstract
A microprocessor is used to control at least one conveyor in a system linking a delivery device (e.g. a cigarette maker) and a receiving device (e.g. a cigarette packer). The conveyor may be controlled in accordance with the calculated deviation in a detected value (e.g. corresponding to stack height) from a target value. Where an analogue signal is produced by the detector device this is converted to digital form and is preferably operated on by a program function so that a linear digital representation or signal relating to the detected value may be produced. For example, the angular displacement of a pivoted sensor arm is used to provide a direct indication of stack height by use of cosine look-up tables held in memory.
