ABSTRACT:
A method of folding laundry sheets and like articles is provided wherein a single operator drapes one edge across a carriage which is made to retreat from the operator while the latter locates the opposite sheet edge, causes the carriage to return, and drapes said opposite edge over the carriage similarly, repeating the process with the partially folded sheet until a complete set of primary or parallel folds is effected. The sheet is then optionally cross-folded once over a bar which can be removed bearing the thus draped sheet for removal from the bar and manual completion of folding. Apparatus provided for use in the process comprises a horizontally reciprocable carriage capable of retaining a sheet draped thereover, with appropriate drive and control means, and an optional cross-folding bar pivotable down upon the carriage after primary folding, and pivotable away and aside from the carriage with the primary folded sheet folded once across said bar.
