Abstract
A method for spreading a laundered rectangular cloth including picking up a portion of the cloth so that the cloth is suspended from the picked portion, and trailing the cloth on a support to position one corner portion, being the trailing end of the cloth, at a predetermined location on the support. After the corner portion has been gripped, the cloth is supported horizontally. The cloth is regripped at two, horizontally spaced apart positions transferred to a conveyor so that a length of one edge of the cloth is straightened and positioned in the downstream end of the conveyor. The straightened edge is grasped and displaced toward a horizontal support bar extending in a direction parallel with the displacing direction to hang the cloth thereon with the opposing short edges being straightened. One of the straightened short edges is fixed to suspend the cloth therefrom in a spread state. A spreading apparatus includes a combination of various gripping, conveying and suspending mechanisms to perform the above method.
