Abstract:
1. A method adopted for fabricating a plurality of double starwheel units in multiple rows with a multi-hole manner, the method comprising: (a) obtaining a plurality of strip-like tools parallel to each other and arranged increasingly closer to be combined with a plate-like assembly fixture, the strip-like tools each having a plurality of recesses formed in two opposing longitudinal sides thereof, and a plurality of module holes formed by each of the recesses and a next recess relating thereto; (b) retaining two sheet-like substrates against an upper surface and a lower surfaces of the plate-like assembly fixture, the two sheet-like substrates each having a plurality of starwheels respectively relating to the module holes, each of the starwheels having a gear-wheel hole and external teeth wherein each has a circumference ranging between that of the gear-wheel hole and that of external teeth of each of the starwheels; (c) covering the plate-like assembly fixture with an exterior mold, and closely pressing the external teeth arranged on the upper and lower surfaces of plate-like assembly fixture; (d) injecting a working fluid into an injection hole in the exterior mold and into the module holes therein, and transforming the working fluid into a sleeve to connect the starwheels of the two sheet-like substrates on the upper and the lower surfaces of the plate-like assembly fixture relating to each other for shaping a plurality of double starwheel units respectively oriented in the module holes; (e) removing the exterior mold; (f) removing a plurality of residents of the two sheet-like substrates; and (g) separating the strip-like tools from the double starwheel units.
