Wincling-off and measuring machine. the long sides of which correspond to the lengthto be given to the folds of the piece, and theshort sides to the width of the piece itself. If a MACHINES EMPLOYED IN FINISHING. 275 piece be unrolled, doubled by hand, and placedon the table, the first metre or the first lengthwill cover the surface contained between the fourrods; if a rod be placed beyond and across oneof the sides in the direction of the width and thefabric be folded upon itself a second fold will beformed and kept in place by a second transversalrod, placed at the other extremity of the rectangle,and by continuing to place rods on each side of therectangle, the whole piece, already doubled, will befolded and the rods are then withdrawn. This methodis much used for heavy goods. Other cottonfabrics are doubled by doubling machines of whichthere are a number of systems.
