Claim:
An anchorless method for manufacturing a toothbrush, comprising the steps of: arranging at least one head component provided with holes ( 21 ) extending therethrough, each of said holes tufted with tufts of synthetic single-yarns; melting bottom ends of said tufts extending from a back side of said head component such that the bottom ends form heads ( 23 a ) with shapes larger than the corresponding holes ( 21 ); substantially covering the heads ( 23 a ) of the tufts at said back side ( 20 a ) with a protection membrane ( 30 ); and completing the back side ( 20 a ) of said head component by injecting a molten material, and subsequently causing the injected molten material to harden, wherein the protection membrane has such an extension as to substantially cover said tuft heads ( 23 a ) at least in areas in a proximity of points of injection of said molten material.
