Patent number: 5013511Abstract: A method of making a slider for use in a slide fastener, which slider is provided with bearings for a pull tab on an upper surface of a slider body on its opposite side to pivotably hold a pintle of the pull tab. By making use of only one slide core, a slider body mold cavity in a mold is blocked from a pull tab mold cavity and at the same time, hollow space portions in the bearings for the pull tab are formed by means of the slide core. After molding the slider body, by retreating this slide core, the hollow space portions in the already molded pull tab bearings are used as a mold portion for a pintle of the pull tab. By injecting an amount of molten synthetic resin having a larger thermal contraction coefficient than the synthetic resin used previously for molding the slider body, into the pull tab mold cavity, the pintle of the pull tab and the pull tab are integrally molded.Type: GrantFiled: December 4, 1989Date of Patent: May 7, 1991Assignee: Yoshida Kogyo K. K.Inventor: Shunji Akashi
