Filament winding apparatus and method

Patent ·
OSTI ID:5361792
This patent describes a method of simultaneously winding thermally-softened filament reinforced thermoplastic strips onto a mandrel. It comprises: supplying the thermally-softened strips; winding the strips onto the mandrel; and ceaselessly urging the strips into generally parallel, contiguous juxtaposition and fusion at a point prior to the strips' first contact with the mandrel and after the strips have been thermally-softened. This patent also describes an apparatus for simultaneously winding thermoplastic-impregnated-filament strips onto a mandrel. It comprises: a rotatable mandrel for receiving the strips; winding means for rotating the mandrel and winding the strips onto the mandrel; feeder means for feedings the strips to the mandrel as the mandrel rotates; and joining means, located between the feeder means and the mandrel, for deflecting the strips from a linear path of travel between the feeder means and the mandrel and for ceaselessly urging the strips into generally parallel contiguous juxtaposition the juxtaposed strips having a width about equal to the added width of the individual strips, the joining means comprising: a heating source for heating the joining means independently of the strips so that the joining means will thermally soften the strips as the joining means deflectively contacts the strips.
