Abstract
An improved vehicle finishing device is disclosed for a rotary vehicle finishing apparatus. The device includes a plurality of finishing units, each of which is mounted on a drum and has a continuous base portion and a plurality of elongated flexible finishing elements. A plurality of stiffeners are also mounted on respective mounting sites on the drum. The base portions of the finishing units bear against the stiffeners when the apparatus is rotated and biased against a vehicle. The stiffeners support the base portions of the finishing units, thereby preventing the finishing elements from collapsing against the drum.
Claims15
In a rotary vehicle finishing apparatus comprising a drum, means for rotating a drum, and means for biasing the drum against a vehicle, the improvement comprising:
- a plurality of finishing units, each finishing unit being mounted on the drum, and each finishing unit including a continuous base portion and a plurality of elongated, flexible finishing elements secured to and extending radially from the base portion;
- and,
- a plurality of stiffeners, each stiffener being mounted on the drum, and each stiffener extending radially away from the drum by an amount substantially no greater than the radial extent of the base portions, such that the stiffeners support the continuous base portions of the finishing units, thereby substantially preventing the finishing elements from collapsing against the drum when the drum is rotated and the drum is biased toward a vehicle, the finishing units and the stiffeners cooperating to substantially prevent the stiffeners from protruding between adjacent finishing elements and coming into contact with the vehicle.
In a rotary vehicle finishing apparatus comprising a drum which includes a plurality of mounting sites, means for rotating the drum, and means for biasing the drum against a vehicle, the improvement comprising:
- a plurality of finishing units, each finishing unit being mounted on a respective mounting site on the drum and each finishing unit comprising at least one ply of cloth such that each of the finishing units defines a continuous base portion adjacent to the drum and a plurality of elongated, flexible cloth finishing elements secured to and extending away from the respective continuous base portion;
- and
- a plurality of stiffeners, each stiffener being mounted on a respective mounting site on the drum and each stiffener extending radially by an amount substantially no greater than the radial extent of the base portions of the finishing units such that the stiffeners are positioned to bear against the continuous base portions of the finishing units, thereby substantially preventing the finishing elements from collapsing against the drum when the drum is rotated and the drum is biased toward the vehicle, the finishing units and the stiffeners cooperating to substantially prevent the stiffeners from protruding between adjacent finishing elements and coming into contact with the vehicle.
In combination with a vehicle finishing apparatus comprising a vehicle finishing device, means for rotating the device, and means for biasing the device toward the vehicle, an improved vehicle finishing device comprising:
- a drum which defines a plurality of mounting sites;
- a plurality of finishing units, each finishing unit mounted on a respective mounting site on the drum, each finishing unit comprising two plies of felt slit across a portion of their widths to define a continuous base portion and a plurality of elongated, flexible finishing elements secured to and extending from the base portion;
- and
- a plurality of stiffeners, each stiffener extending radially from the drum approximately as far as the continuous base portion of the finishing unit, each of the plurality of stiffeners being mounted on the drum between two adjacent finishing units such that the finishing units and stiffeners alternate around the periphery of the drum and the stiffeners support the finishing elements, thereby substantially preventing the finishing elements from collapsing against the drum when the drum is rotated and the drum is biased toward the vehicle, the finishing units and the stiffeners cooperating to substantially prevent the stiffeners from protruding between adjacent finishing elements and coming into contact with the vehicle.
