Abstract: The invention relates to a system and method for constructing a vehicle-mounted single core broom system for use in clearing snow or debris from airport runways. The rotatable broom system utilizes a single piece hollow tubular core which is attached to the front of the vehicle. A low speed/high torque radial piston hydraulic motor is mounted inside one end of the broom core. The motor case rotates as the motor operates. Because the motor case is directly connected to the broom core, this rotation causes the broom core to rotate. A rotatable mounting is attached to the opposite end of the broom core. The broom core is 46 inches in diameter and dynamically balanced. These features enable higher broom tip speed and improved sweeping efficiency. Linear bristle cassettes are slid horizontally into the broom core sections, facilitating easy removal and replacement of the bristles as they become worn.

Abstract: The invention concerns a rotatable grinding/polishing tool, an apparatus with such a tool and a method for using such a tool.

Furthermore, the tool has holding elements, preferably in the shape of brushes, likewise extending radially outwards from the roller. The holding brushes have substantially lesser length than the flaps and the reinforcing support brushes. At the same time, the tangential stiffness of the holding brushes is considerably greater than the tangential stiffness of the flaps and the support brushes. The length of the grinding flaps is preferably so that by grinding or polishing, the flaps are capable of extending beyond an adjacent holding element.

Abstract: A method for manufacturing a sweeper or abrasive element is disclosed. The abrasive element is manufactured from a U-shaped plastic profile having an aperture in which are placed abrasive lamellae, supporting bristles and heat-dissoluble plastic threads. By heating above the plasticization temperature of the plastic, total embedding of the bristles and abrasive lamellae occurs thereby forming an integral unit. This ensures that the bristles and/or abrasive lamellae will not separate during use of rotating abrasive or polishing tools in which the abrasive elements are included. As the abrasive elements are of plastic material they are flexible and able to adapt to different diameters of abrasive or polishing tools. The user, therefore, only needs to have a supply of abrasive elements, cut into suitable lengths depending on the diameter of the tool in which the abrasive elements are to be replaced.
