Description:- To achieve consistent high quality carding, proper maintenance of both Metallic card clothing and Tops are essential. Unlike rigid metallic wires ,tops are more prone to loading with impurities like fibre fragments, seed coats, micro dust while processing cotton and spin finish, dye/tint particles etc. While processing synthetic fibres. Consistent performance of the tops is greatly affected due to this. Commonly used practice of cleaning of tops with hand cleaning cards, compressed air and rollers with cleaning fillets can perform cleaning only to a certain extend, however throught cleaning of wire points in tops is not possible As performance of tops greatly depend on this, Sharprite-tops has been developed to address this issue .The innovative system of cleaned both at tips and sides to enable the tops to perform as good as new.

At the time of manufacturing of flat tops the tip of wire points are made very fine with a back off so that it becomes extremely sharp. This sharpness is crucial for improved carding performance. With the working of material wire tips in tops starts wearing. To retain sharpness int the wire point grinding is an essential operation. While grinding tops with conventional tops grinding machine a land is created on the wire points of tops. This land on the wire tips go on increasing with subsequent grindings resulting in lower carding efficiency. In order to maintain the wire tips share similar to the original wire tip shape, which is a key factor in achieving good carding, a new resharpening concept is employed in sharprite tops.

In Sharprite tops a high speed rotating wheel with special abrasive fillet mounted on it traverses the full width of the tops. A patented feeding mechanism allows precise adjustments of the grinding roller to the flat wire tips, so that a grinding depth upto one thousands of an inch is achievable. The precise grinding load over a smaller area on the flat tops helps in cutting the back edge of the wire points, so as to retain wire tip shape very similar to the original shape OF THE WIRE POINTS.

Until now the initial leveling of the flat tops after mounting is done off the card with conventional flat grinding machines. The process is time consuming and slow. In Sharprite tops thanks to its precise feed adjustment mechanism, the initial leveling is possible on card.

During maintenance grindings with conventional on card grinders as the feed is adjusted by observing the sparks, the perfect setting on card grinders as the feed is adjusted by observing the sparks, the perfect setting of the grinder depends on the skill of the operators. Frequent correction of the setting during operation is a common problem leading to uneven setting between the flat and the cylinder. With Sharprite tops this problem is eliminated due to its cam feeding system.

Both the operation of cleaning as well as resharpening of wire points in tops can be done using a unique single device.
