fiber purity and straightness by providing for a more efficient method of short fiber removal application_number US 25220294 A description an improved carding machine for high voltage short fiber removal is provided the mechanism utilizes a number of small rollers arrayed in a semicircular configuration positioned near the pylon roller that are driven synchronously along the conveyor belt furthermore the conveyor belt can be constructed out of a metallic or non metallic material that conducts electricity short fiber elimination has a major influence on yarn quality and short fiber elimination is mainly handled by carding machines the amount of short fiber removed is dependent on the quality sought and the raw material utilized generally 15 25 however due to the design of a carding machine the carded strands are often damages during straightening lapping and other preparation processes including the removal of short fibers from an economic point of view this is a wasteful process there are some new types of devices such as that disclosed in the u s pat no 08 049 499 shown in fig1 such systems utilize a high voltage field produced axially across long and short fibers wherein the debris removal function differs in that a vacuum device is utilized to remove the short fibers and debris the entire device is installed at the front of the carding machine while the originally installed doffer and stranding equipment are removed a.
