Abstract
A method of gripping corners of a strip of cloth, which may be applied to, for example, systems for spreading strips of cloth, including a first step of suspending a rectangular strip of cloth by gripping one corner thereof, a second step of gripping the lowermost corner portion of the strip suspended in the first step, a third step of raising substantially vertically either one of the gripped points of the strip gripped in the first and second steps, a fourth step of applying braking force to the other gripping point in order to apply tension to the strip, and a fifth step of holding substantially horizontally one side of the strip having a corner portion which is adjacent to the gripped points and gripping the corner portion of the strip which is adjacent to the gripped points of the strip gripped in the first and second steps, respectively. The method enables a strip of cloth discharged from a drier to be automatically spread, thus relieving operators from the operation in the inferior environment and automating the operation in laundry works. Also disclosed is an apparatus which may suitably be employed to carry out the above-described method.
