Abstract
A feeding device for preneedle punching of nonwoven fabrics that includes a stripper plate, a bed plate, a linear belt conveyer and a plurality of needles. The linear belt conveyer passes through a space between the stripper plate and the bed plate and conveys fiber batt to the space. Then, the needles punch and tangle the fiber batt in the space.
