Abstract
An apparatus for manufacturing round brushes includes motor-driven driven rollers (22, 26) which on twisting of the wire halves urge wire to a rotating gripper (60). The wire material slides along diverters (52, 54).
Claims14
An apparatus for manufacturing round brushes that include bristles clamped between two wire portions of a folded wire, comprising
- motor-driven drive rollers that move the wire in a longitudinal direction,
- a bending part movable transversely to the wire,
- opposed counter-brackets that are spaced apart from each other and that are arranged on a side of the wire opposite to the bending part,
- wherein the bending part can be shifted between the counter-brackets, which process bends the wire between itself and the counter-brackets to obtain bent wire with a V-shape or U-shape in order to form wire halves,
- a bristle feeding device for feeding bristles to the bent wire, and
- a rotating gripper that can grasp the bent wire and twist the same during the feeding of bristles in order to anchor the bristles in the wire,
- wherein diverters spaced apart from each other are provided for abutment of the wire, along which the wire halves are guided, wherein the diverters form a transition from non-bent wire portions of the wire halves to wire portions leading to the rotating gripper transversely to a longitudinal direction, and
- wherein the counter-brackets and the diverters are different parts that can be brought into contact with the wire and out of contact with the wire, wherein the counter-brackets are distanced from the bent wire during twisting.
