PURPOSE: An expander for preventing crease of a fiber fabric is provided to prevent product quality reduction due to crease and to obtain a fiber fabric with improved quality. CONSTITUTION: An expander for preventing crease of a fiber fabric comprises: a base part(10) formed in a base block(11); a driving stage(20) which is mounted at the upper portion of the base part and vertically and horizontally moves, and adjusts a position for expanding; a driving cylinder(30) which is mounted at the upper portion of the driving stage has a left and right reciprocating cylinder(31) and forward and backward reciprocating cylinder(32); a buffering device which is coupled at the front end of a piston rod of the forward and backward reciprocating cylinder and is formed between the forward and backward reciprocating cylinder and an expanding roller(50); the expanding roller which is coupled to the front end portion of the buffering device, and spreads the fabric; and a control unit for controlling the driving cylinder. |
