Abstract
A process and device are provided to introduce a fiber fleece through the nip of a pair of calendar rollers. Pressurized air is directed to a cylindrical segment of a sliver guiding system down stream from a tapered conical section so that the pressurized air draws the fiber fleece through the sliver guiding system without requiring lateral venting or expansion of the pressurized air. The pressurized air vents from the front end of the cylindrical section adjacent the nip of the pair of calendar rollers.
