Abstract
The invention involves a slide assembly for a zipper, and a method for manufacturing a zipper slide assembly. The slider assembly is formed in a single die cast operation to include the slider and the pull member being formed simultaneously. At least one side shifting slide is incorporated into the die, which allows the bridge and pull loop to be formed with their full geometric shape and without the converging flat surfaces required in the prior art.
