Abstract: A toothbrush in the form of a manual toothbrush having a rectangular bristle array (1) or in the form of an electric toothbrush having a round bristle array (1), formed from individual bristle bundles (2), arranged adjacent to each other on a brush head and standing erect at approximately right angles thereto is provided. At least some of the individual bristle bundles (4) are at least partly inclined or roof-shaped with respect to a plane approximately parallel to the brush head (2), such that bristles in the bristle bundles (4) stand to differing heights whereby the terminal surfaces arranged at the applied ends of the bristle bundles (4) are embodied as inclined surfaces (5) or as partly inclined surfaces. The bristle bundles (4) are arranged in a line adjacent to each other along imaginary straight or curved connecting lines, or for round brushes, along segmental or circular connection lines.

Abstract: Individual bristles and/or batches of bristles are withdrawn from one or more magazines and are mechanically or pneumatically transferred to positions of alignment with the sockets of one or more forms. The individual bristles and/or batches of bristles are thereupon drawn into the aligned sockets by suction prior to being welded or glued to an adapter which constitutes or forms part of a brush body and defines the open ends of sockets during drawing of bristles into the form or forms.

Abstract: A toothbrush wherein the front end face of the handle has a flat projection which is receivable in a complementary socket in the adjacent end face of the detachable bristle carrier and the projection is integral with an arrowhead-shaped male detent which is detachably snapped into a recess extending from the socket into that surface of the carrier from which the bristles extend.
