Abstract
A cloth spreading apparatus includes: a spreading unit having spreading clamps that spread an upper-side part of a fed cloth in a right-left direction; and an ejection unit having an intermediate movable body that releases the upper-side part of the cloth that the intermediate movable body has received from the spreading clamps in the forward position and held onto an upper surface by sucking, and a belt conveyor that receives the upper-side part of the cloth released by the intermediate movable body and ejects the entire cloth backward. The ejection unit has: a large number of suction holes that are dispersedly disposed in the intermediate movable body's upper surface; a negative pressure source that sucks out air inside the intermediate movable body to form a negative pressure region inside the intermediate movable body; and sucking force maintaining means that maintains a sucking force of the suction holes
