    摘要: Means and method for spreading cloth on a moving support surface from a roll or bolt of cloth with a negligible amount of tension on the cloth to cause the cloth to lie flat. The cloth is rolled off the bolt into a slack loop where sensing means determine the extent of the loop and generate signals to control the dispensing of cloth off of the roll into the loop. The cloth is then pulled out of the slack loop over a smooth surface onto the surface of a belt by the mere friction between the cloth and the belt, the tension in the cloth on the belt being minimal, thereby avoiding forming of tension wrinkles in the cloth.
