Abstract

In a conveyor for continuously conveying linens or like materials one by one as gripped at a plurality of points by chucks moving along a rail, a first sensor for detecting passage of the chuck is disposed at a predetermined position along the rail, and two or more second sensors for detecting existence of a linen are disposed at two or more predetermined positions. Means is provided for expanding a distance between adjacent chucks being moved continuously in the proximity of the first sensor. In response to detection signals issued from the sensors, the condition of the chucks gripping the linens can be recognized whether a given chuck is gripping a front corner, a rear corner or a middle point on an upper edge of a linen, it is gripping only one point of a linen, or it is gripping nothing (that is, idle).
