ABSTRACT:
An automatic laundry sorting machine comprising separate sorting stations having individually driven conveyor units for feeding and sorting folded laundry articles according to size. Sorting and sensing means are associated with at least one of the conveyor units to actuate a release mechanism for articles of selected predetermined size. Articles of other sizes are not released but are passed to subsequent stations where further sorting may occur. Articles not fitting any of the predetermined size-sensing criteria can be passed or by-passed through the conveyor units and discharged outside the system. Alternative embodiments including counters strategically placed in subsequent stations and unique jam eliminating circuitry are described.
