Abstract: Skin categorizing apparatus comprises a conveyor on which skins are categorized by automatic area scanning and thickness measuring means generating data for transmission to a remote location for control and data processing equipment. Displays at the conveyor location are driven by the control equipment to show data first transmitted thereto. The area and thickness means is capable of dealing with a single skin or two sides of split skins simultaneously. Thus two sets of displays are shown one at each side of the conveyor. Data entry means serves for a skin quality input and data generation with an associated display. The control equipment includes a supervisor's display unit and two printers one for logging work progress and the other for printing out batch labels or advices when a batch is complete for a particular order.
