ABSTRACT:
Wooden members are joined with sheet metal connector plates having integrally struck teeth projecting from one side. The wooden members are placed between first and second pressheads. A coiled composite of connector plate stock has first and second lengths of connector stock in juxtaposition and with intermeshing teeth. The first and second lengths of connector stock are unwound separately and oriented so that the teeth thereof point toward the wooden members to be joined. A cutting means associated with the pressheads cut connector plates from the stock and the plates are positioned on opposite sides of the wooden members and at the junctures to be joined. The pressheads press the plates into the wooden members. The connector stock is provided as a free coil and has the advantage that no spool, reel, or like supporting device is required. Further, the composite of connector stock has no teeth projecting from outer surfaces thereof.
