Abstract
To provide a cloth spreading device capable of operating stably. The cloth spreading device includes: introduction chucksin a pair that grip corner portions of a cloth C; an up and down moving devicethat moves the introduction chucksin a pair up and down; extension chucksin a pair that receive the cloth C from the introduction chucksin a pair and grip corner portions of the cloth C; and a transversely moving devicethat moves the extension chucksin a pair transversely. The up and down moving deviceis driven by an actuator permitting speed control and position control. Thus, an external factor does not cause large change in the operation of the up and down moving deviceto achieve stable upward and downward moving operations of the introduction chucks. The introduction chuckscan be moved and stopped at will. This eliminates the need for a position sensor to achieve reduction in facility cost.
