<p>In order to clean a soiled square cloth, it has to be subjected to washing, dehydrating, drying, spreading, ironing and packaging but the spreading step has been carried out manually since it has not yet been automated. Some spreading methods and apparatuses have been proposed in which one corner portion of a square cloth and another corner portion thereof diagonally opposite to the first-mentioned corner portion are gripped and hung so that the square cloth is in the shape of an inverted pyramid, the resultant square cloth which has non-twisted straight edges being gripped at an arbitrary corner portion thereof and one point, which is a predetermined distance away from this corner portion, of one edge of the cloth or a corner portion adjacent to the first-mentioned corner portion, whereby the square cloth is then spread. By such methods and apparatuses, the spreading step is automated, so that all of the steps of a soiled square cloth cleaning method are automated.</p> |
