Abstract:
1. A method of manufacturing a waterproof wire harness, comprising the steps of: providing a plurality of wires; providing a coating position at which an water sealing agent in an unsolidified condition is coated on an outer periphery of each wire; providing a first mold formed with a groove; providing a second mold configured to be inserted into the groove, the second mold having a molding face which defines a space between a bottom portion of the groove, the space having a cross section which is identical with a cross sectional shape of a through hole of a grommet through which the wires are inserted; conveying the wires separately and individually one by one so as to pass through the coating position while individually coating the outer periphery of each wire with a predetermined amount of the water sealing agent in an unsolidified condition, wherein the sealing agent is caused to drop onto each wire; throwing the wires individually coated with the water sealing agent into the groove of the first mold, wherein the coated wires are thrown sequentially into the groove of the first mold; inserting the second mold into the groove; pressing the wires in the groove such that the unsolidified water sealing agent fills interstices of adjacent wires while solidifying the water sealing agent; and releasing the second mold from the first mold after the water sealing agent is solidified.
