ABSTRACT:
A hand-held clipper for removing entangled fibers from the surface of fabrics has a grip handle with a cutting head. The cutting head comprises a perforated shear foil and cutter blades rotating in shearing engagement with the interior face of the shear foil. The shear foil is curved into a generally semi-cylindrical configuration having a longitudinal axis and define first and second side faces on the opposite sides of a curved top portion. The cutter blade has a cutting edge extending along the longitudinal axis of the shear foil and is driven to rotate in one direction about a rotations axis, which is common to the longitudinal axis of the shear foil, so as to move along the curved shear foil continuously from the first side face toward the second side faces. The first side face thus located rearwardly of the top portion of shear foil with respect to the rotating direction of the cutter blades is configured to have perforations larger than in the second side face located forwardly of the top portion in the rotating direction such that the entangled fibers once entered through the perforations in the first side face and clipped by the cutter blades can be well prevented from flowing outwardly through the perforations in the second or opposite side face of the shear foil.
