To make only one cloth piece corner end appear by a high probability when automatically spreading a rectangular cloth piece after being washed and dried in a laundry plant.

The corner end providing device for the rectangular cloth piece used in a spreading apparatus for automatically spreading the rectangular cloth piece Y carried in a rounded state into a rectangular shape includes a pair of rollers 31 and 32 for clamping the vertical middle position of the rectangular cloth piece Y lifted by holding an optional part from the horizontal direction on both sides thereof, a motor 35 for rotating both rollers 31 and 32 to the cloth piece advance side, and a detector 37 for detecting that a lower end Yc of the cloth piece is positioned at the lower surface close position of the joint part of both rollers 31 and 32. By stopping the rotation of both rollers 31 and 32 when a cloth piece lower end detection signal is put out from the detector 37, one cloth piece corner end Yc is made to appear near the joint part of both rollers 31 and 32 at a high probability.
