Preferably, the halves may be pressed on the waterproof layer by the pressing device at a pressure range from 10 kg/cm2 to 30 kg/cm2 and in a temperature range from 40° C. and 140° C. to secure the waterproof layer and the releasing layer together - S905: Removing the releasing
layer 4 from thewaterproof layer 31, i.e., only thewaterproof layer 31 secured to thehalves 30. - S906: Drying both the
waterproof layer 31 and thehalves 30 in the oven again. - S907: Cooling both the
waterproof layer 31 and thehalves 30, removing same from the continuous flow production line, and placing same in an environment to provide a finished waterproof zipper. Preferably, the environment may be a room environment with room temperature, or may be a predetermined temperature lower than the room temperature. Both the waterproof layer and the halves are placed in the room environment for five to seven days to produce a finished waterproof zipper. As a result, a complete zipper is finished. - The invention has the following advantages: Electroplating step is eliminated. Manufacturing process is simplified. Thickness of the zipper is relatively low. The zipper is sufficiently flexible.
- In another process of manufacturing the waterproof zipper of the present invention, such as the waterproof zipper depicted in
FIG. 6 , including the following steps: - Guiding the waterproof layer to a position above two half tape members on a continuous flow production line;
- Coating a waterproof layer on a releasing layer;
- Drying both the waterproof layer and the releasing layer in an oven;
- Pressing the two half tape members on the waterproof layer by a pressing device to secure the waterproof layer and the releasing layer together;
- Removing the releasing layer from the waterproof layer;
- Drying both the waterproof layer and the half tape members in the oven again;
- Cooling both the waterproof layer and the half tape members for a predetermined period of time;
- Removing both the waterproof layer and the half tape members from the continuous flow production line;
- Placing both the waterproof layer and the half tape members in an environment; and
- Connecting the two half tape members to two rows of protruding teeth to produce a finished waterproof zipper. In this embodiment, the
water proof layer 31 provides excellent waterproof effects at a portion where thehalf tape member 300 connecting to the row of protrudingteeth 301. - While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
