  • CATCH BASE FOR ATTACHING CATCH OF SNAP FASTENER
    Publication number: 20090113678
    Abstract: To provide a catch base capable of firmly attaching a catch of a snap fastener to a cloth. The catch base includes six claws for attaching the catch formed at regular intervals. The catch is put on one side of the cloth, and the claws are fitted into catching portions formed at the backside of the catch from the other side of the cloth. The catch base and the catch are then swaged together. With this, the strength in attaching the catch is increased by 20% due to the effect of the six claws, and the catch is not removed during the use, resulting in an improved safety.
