PURPOSE: A raw fabric punching apparatus is provided to guarantee punching time for melting a raw fabric by contact heated punching pins with the raw fabric, thereby preventing quality degradation of punched holes. CONSTITUTION: A raw fabric punching apparatus(100) comprises at least two transferring rollers and a punching device. The transferring rollers transfer raw fabrics. Heated punching pins(124) are descended so that can be moved by connecting with the raw fabric while punching holes on the raw fabric. If the punching work is finished, the punching pins are returned to the initial position. |
