A cassette brush, a vehicle provided therewith and a method of producing a cassette element for a cassette brush

A brush (1) intended for industrial use comprising:

• one or more bristle bunches (9), each formed by a plurality of elongated bristles (10),
• one or more cassette elements (5), each having at least one said bristle bunch (9), and
• a cassette element holding member (3) provided with one or more fastening members (4), each fastening member (4) being configured to removably secure at least one said cassette element (5) at the holding member (3),
• at least one of said cassette elements (5) comprising:
• a body (6),
• one or more recesses (7) at a first outer surface (8) of said body (6), each recess (7) being configured to receive a middle portion (11) of a bristle bunch (9) therein, and
• a securing wire (14) configured to secure said middle portion (11) of said bristle bunch (9) in said recess (7), with the middle portion (11) of the bristle bunch (9) pushed down in the recess (7) such that the middle portion (11) forms a substantially U-shape therein and a first (12) and a second end portion (13) of the bristle bunch (9) extends out of the recess (7) in a direction away from said first outer surface (8) of said body (6), by extending over every bristle (10) contained in a bottom portion (15) of the U-shape of the bristle bunch (9), in a direction perpendicular to the extension of the bristle bunch (9) in said bottom portion (15), to secure the bristle bunch (9) in the recess (7) by urging parts of said U-shape of the bristle bunch (9) against one or more surfaces of wall (17) and/or bottom portions (18) of the recess (7),
• wherein at least a majority, preferably all, of the bristles (10) of each said bristle bunch (9) are made of a synthetic material, preferably a plastic material, and
• said at least one cassette element (5) further comprises:
• means configured to counteract movement of the bristles (10) in said bottom portion (15) of the bristle bunch (9) with respect to each other and/or with respect to said securing wire (14).

A method of producing a cassette element (5) having one or more bristle bunches (9) to be used with a brush (1) intended for industrial use, comprising the steps of:

• pressing a middle portion (11) of each said bristle bunch (9) down in an associated recess (7), located at a first outer surface (8) of a body (6) of the cassette element (5), such that the middle portion (11) forms a substantially U-shape therein and a first (12) and a second end portion (13) of a bristle bunch (9) extend out of the recess (7) in a direction away from said first outer surface (8) of said body (6),
• securing said middle portion (11) of each said bristle bunch (9) in the respective recess (7) by arranging a securing wire (14) over every bristle (10) contained in a bottom portion (15) of the U-shape of said bristle bunch (9), so that the securing wire (14) extends in a direction perpendicular to the extension of the bristle bunch (9) in said bottom portion (15) and secures the bristle bunch (9) in the associated recess (7) by urging parts of said U-shape of the bristle bunch (9) against one or more surfaces of wall (17) and/or bottom portions (18) of the recess (7),
• wherein at least a majority, preferably all, of the bristles (10) of each said bristle bunch (9) are made of a synthetic material, preferably a plastic material, and
• arranging means configured to counteract movement of the bristles (10) in said bottom portion (15) of the bristle bunch (9) with respect to each other and/or with respect to said securing wire (14).
