Abstract:
A method for manufacturing a sweeper or abrasive element for use in a rotating sweeper, abrasive or polishing tool comprising providing bristles or lamellae of abrasive cloth and rigidifying bristles for retention in a substantially U-shaped plastic profile, the profile having a bottom and two legs projecting from the bottom, manufacturing the profile in a compressed state wherein the legs are pressed towards each other and elastically yielding and forming the profile having a substantially triangular cross-section in an initial state, and forming the profile longitudinally flexible in a plane perpendicular to the bottom with the two legs being spaced, inserting bristles between the two legs or inserting abrasive lamellae adjacent one of the two legs and rigidifying bristles adjacent the other leg, providing an adhesive member in the profile for embedding the bristles or the rigidifying bristles and the abrasive lamellae to the bottom of the profile to form a unitary structure of the profile and bristles or the profile, rigidifying bristles, and abrasive lamellae adhered to each other, restoring the U-shaped profile back to the initial state with upper ends of the two legs approaching each other thereby squeezing and retaining the bristles or the lamellae and the rigidifying bristles and cutting the element formed into desired lengths.
