Abstract
Air channels (11) are provided in a needle strip for the removal of contaminants that are deposited in the open passageways (F) between the needle points (4), which air channels can be connected to a compressed air source or a vacuum source via an air chamber (15). With die-cut and swaged needles (1), the air channels (11) are preferably formed by an extension of the swaging (10) into the region between the cover plates (2,3). Pursuant to the cleaning process, compressed air, preferably pulsed, is directed at the point region for cleaning purposes.
Claims13
Needle strip, in particular a top comb, for textile machinery and the like, comprising at least one row of needles and first and second cover plates, said first and second cover plates holding in place said row of needles, wherein the points of the needles extend to a certain distance past the bottom edge of said cover plates, thus forming open passageways between the needles, and wherein a cleaning appliance for the removal of deposits that have settled in the open passageways is associated with the needle strip, characterized in that the needle strip comprises at least one air channel (11) in order to conduct a flow of air (17) through or past the open passageways (F) to clean them.
Needle strip comb for textile machinery, comprising at least two rows of needles, characterized in that an air chamber (15') is disposed between the two rows of needles (1), and further comprising means for blowing air through said air chamber and between said two rows of needles.
Process for cleaning a needle strip which forms part of a combing machine, the needle strip having at least one row of needles held in place especially between first and second cover plates, wherein points of the needles extend a certain distance past the bottom edge of the cover plates, thus forming open passageways between the needles, the needle strip further having at least one air channel in order to conduct a flow of air through or past the open passageways to clean them, comprising cleaning the needle strip by compressed air.
