  • Patent number: 4061326
    Abstract: A system with an ironer and a folder for pressing and folding flatwork and having a controller for sequentially actuating a folding mechanism for making folds at selected intervals in the flatwork. The controller includes a pulsing network for generating clock pulses which occur at a basic rate and for generating clock pulses which are derived from the basic rate clock pulses and which occur at rates that are multiples of the basic rate. Counters are provided for processing the derived clock pulses and for generating command wisgnals which define fold position signals. The command signals sequentially actuate the folding mechanism for making folds in the flatwork at selected intervals.
