摘要

PURPOSE: An apparatus for transferring a material is to effect an easy transfer and an accurate fixing of the material in a marking equipment, thereby improving its quality and productivity. CONSTITUTION: The apparatus comprises a transfer unit(B) for a material. The transfer unit comprises a guide rail(11), a conveyor belt(12) and a stopper(13). The guide rail guides both sides of the material. The conveyor belt is mounted in an inner side of the guide rail. The conveyor belt is operated by a step motor(15). The stoppers are symmetrically disposed about a centerline of the material. When one of the stoppers is operated, the other stands by. The guide rail has a ball screw(16) to adjust its width according to a change of width of the material. The stopper is moved by one pitch prior to the movement of the material. The material is then transferred by only one pitch on the conveyor belt.
