Zusammenfassung:	A method and apparatus for a reusable resin distribution line for use in conjunction with a resin transfer molding apparatus is disclosed. The apparatus includes a soft tool and a hard tool (i.e., mold). In the illustrative embodiment, two inflatable bladders are disposed on a side of the soft tool, wherein a bridge spans the bladders. The soft tool is coupled to the bridge. When the bladders are inflated, the bridge moves away from the hard tool, drawing the soft tool away from the hard tool in the region between the bladders. This creates a temporary passage or reusable resin distribution line for distributing resin to a reinforcement constituent disposed between the soft tool and the hard tool.
