- the length of the chain assemblies 343 and 353 is extended while unfolding, and may be disposed on the upper side of the clothing and extended to a length capable of pressing the upper side of the clothing.
- the control unit 500 may move the first guide chain housing 341 and the second guide chain housing 351 downward by operating the sixth moving motor M6 and the eighth moving motor M8. Accordingly, while the chain assembly 343 of the first guide arm 340 and the chain assembly 353 of the second guide arm 350 descend, the clothing may be pressed with a predetermined pressure. Therefore, clothes can be supported by the first guide arm 340 and the second guide arm 350, and the cross-folding position can be guided. In this case, the cross-fold line of the clothing becomes clearer, and the clothing can be neatly folded.
- the controller 500 operates the first chain drive motor MC1 and the second chain drive motor MC2 to move the chain assembly 323 of the first folding arm 320 and the second folding arm 330.
- the length of the chain assembly 333 is extended. Accordingly, the chain assembly 323 of the first folding arm 320 and the chain assembly 333 of the second folding arm 330 are elongated along the first direction.
