Parts Designation of barb

Fiber is pushed forward by barbs through fiber mesh material, therefore it is critical to determine the shape, quantity and array style of barbs on the edge of functional section as well as the length, depth, height and undercut angle of barbs. 3D formeal barbs in G and GB style can lengthen the service-life of prickers. Commonly used prickers are with 3 barbs on each edge, and for special use of substrate cloth material, it is with barbs only on one or two edge The direction of bending crank can be inclined left(-) or right(+), which will protect the substrate cloth material lengthwise and sidelong, and reduce the damage to the minimum. The direction of prickers can be determined through the location of barbed-edge.
