Abstract
A filament winding payoff unit and process for applying strands of adhesive impregnated filament material arranged into a gap-free band to a rotating mandrel. A plurality of side-by-side slightly overlapped impregnated filament strands are passed over bars between tines of combs for positioning when leaving the payoff head. The payoff head is positionable toward and away from the rotating mandrel to allow for mandrel longitudinal dimension changes while maintaining the payoff head roller in contact with the mandrel at a predetermined pressure thereagainst. The payoff head is also freely pivotable horizontally to maintain a proper angle of filament application to any changing mandrel longitudinal configuration.
