An electrically operated shop towel vending machine for dispensing a clean shop towel only in response to the proper input of a satisfactory dirty towel inspected as to length, strength or texture and bulk. The machine cabinet is locked in an effort to prevent lost and wasted shop towels and has an input opening for the dirty shop towel and an output exit for a clean shop towel. The input section of the machine includes a continuous, endless chain with protruding towel pick-up members on which a dirty towel is hung. An inspection procedure includes a rotatable towel contact wheel contacting the towel to determine the proper length of the towel and a switch positioned to determine the proper bulk. The input section of the machine is electrically related to the output section so that the clean shop towel is dispensed only if a dirty shop towel passes inspection. Clean shop towels are simply stored by piling in the cabinet near a towel dispensing conveyor system including a pick-up belt and a shedding arrangement whereby clean towels are constantly being conveyed to the shedding or separating arrangement and by means of a special relationship of relative motion of conveyors only one is fed through and dropped to the dispensing exit each time one dirty one is put in the machine. Other details include the electro-mechanical arrangement of the input section and the electro-mechanical arrangement of the output conveyor section and the details of the shedding arrangement.
