Abstract: A running carriage (33) delivers, spreads, and piles a sheet material to be spread to form a piled sheet material (24), while running on a spreading table (22) of a cloth spreading machine (21). The piled sheet material (24) is placed on an underlay sheet (25) which has a larger area than that of the piled sheet material (24). At the bottom of the running carriage (33), a foot presser (27) is provided. The foot presser (27) is designed to be vertically displaced by a cylinder (28). A blower motor (29) drives a fan (30) to blow air through nozzles (31) towards the surface of the spreading table (22), thereby reducing the load of the piled sheet material (24). The underlay sheet (25) is pressed by the foot presser (27) and the running carriage (33) starts running, whereby the piled sheet material (24) is delivered.
