PROBLEM TO BE SOLVED: To provide a drawing/contraction selective drawing machine for sheet materials which can execute selectively a longitudinal-direction drawing treatment and a lateral-direction drawing treatment of a sheet-like material and a longitudinal-direction contraction treatment and a lateral-direction contraction treatment of a sheet-like by using a single drawing machine for sheet-like materials.SOLUTION: A drawing/contraction function selective drawing machine for sheet materials can execute selectively a longitudinal-direction drawing treatment and a lateral-direction drawing treatment of a sheet-like material by feeding a sheet-like material from one end of a path while causing the carrying side of equal-length links 201 to run in the running direction from the one end to the other end and a longitudinal-direction contraction treatment and a lateral-direction contraction treatment of a sheet-like material by feeding a sheet-like material from the other side of a path while causing the carrying side of equal-length links 201 to run in the running direction from the other end to the one end. |
