The utility model relates to a modified semi-automatic spreading device. The modified semi-automatic spreading device comprises a spreading table, cloth holders, an automatic spreader and two cutting machines fixed at two opposite ends of the spreading table. A piece of cloth is supported on the cloth holders, and expanding cloth material of the cloth is spread on the spreading table in a multilayer plane shape. Each cloth holder comprises a frame body, a first support frame, a second support frame and a plurality of fixing shafts. The automatic spreader comprises two parallel guide rails, two sliding blocks, a spreading rod and two spreading motors. Each cutting machine comprises a lifting table, a guide rod, two locating parts, a sliding part and a blade. The modified semi-automatic spreading device has the advantages that two operators only need to coordinate spreading respectively at two ends of the spreading table, so that running back and forth for spreading is avoided and labor intensity of the operators is reduced; the labor intensity of the operators is further reduced due to the fact that the operators can pull a plurality of pieces of cloth one time; and the cloth is prevented from dropping from the cloth holders during the process of pulling.
