Abstract: The crimper has a pair of feed rollers to supply fiber traveling therebetween. The feed rollers rotate at a first speed. A pair of outlet rollers receive fiber from the feed rollers and rotate at a second speed slower than the first speed. A pair of side walls sandwich the feed rollers and the outlet rollers. A pair of floating scrapers are supported by move with the feed rollers, the outlet rollers and the side walls. Fluid is supplied to and ejected from the scrapers such that a fluid bearing is created at least between the scrapers and the feed rollers. There are two pairs of outlet rollers with a belt rotating about each pair of outlet rollers. For each pair, a first of the outlet rollers is adjacent to the scraper and a second of the outlet rollers is displaced from the scraper. A space between the scrapers defines a crimping chamber. The first outlet rollers are moved toward and away from one another, thereby causing the crimping chamber to open and close.
