Abstract
A method and apparatus are provided for forming textile pads from a textile batt. The method includes the steps of splitting an incoming single textile batt and forming partial thickness textile batts, applying an adhesive to outer surfaces of the partial thickness textile batts, and adhering vapor barriers to the partial thickness textile batts. The apparatus comprises a pair of feed rollers for receiving a textile batt, a splitting knife downstream of the pair of feed rollers, adhesive appliers positioned downstream of the splitting knife and capable of applying an adhesive to outer surfaces of the partial thickness textile batts, vapor barrier supply positioned downstream of the adhesive appliers and capable of supplying vapor barriers that contact the outer surfaces of the partial thickness textile batts, pressure rollers positioned downstream of the pair of vapor barrier supply rollers.
