Abstract:
A sanding drum assembly in one embodiment includes at least one elastic friction member defining an outer perimeter, a plurality of feet located inwardly of the at least one elastic friction member, each of the plurality of feet including a movable portion movable between a first position whereat the plurality of feet define a first outermost circumference and a second position whereat the plurality of feet define a second outermost circumference, wherein the second outermost circumference is larger than the first outermost circumference, and an actuator, wherein the plurality of feet and the actuator are configured such that as the actuator and the plurality of feet change from a first configuration to a second configuration, the plurality of feet are forced from the first position to the second position.
Abstract:
The invention is directed to an improved abrasive pad (15). In the preferred embodiment, the abrasive pad is comprised of an inner core (16) having an outer surface (19), a strip of abrasive material (18), the strip of abrasive material wrapped around the outer surface of the inner core, and a central throughbore (20) extending through the material and the inner core and adapted for engagement with a torque-producing device. The outer surface of the abrasive pad may comprise a top surface (21), a bottom surface (22), a front surface (23), a rear surface (24), a right surface (25), and a left surface (26), and the abrasive strip may be wrapped over the right surface, the bottom surface, the left surface, and the top surface to form a first layer (28) of abrasive material. The abrasive strip may be wrapped around the inner core at least twice to form at least a second layer (29) of abrasive material. The abrasive material may be sandpaper and the throughbore may be threaded (35) for engagement with a mandrel. The throughbore may further comprise a grommet (36) holding the strip of material around the inner core. The inner core may be generally rectangular and further comprise at least one chamfer surface (38).
Abstract:
L'invention concerne un dispositif multi-positions à serrage progressif d'une pièce (30-43) ayant un alésage rond ou ovalisé, caractérisé en ce qu'il comporte; une bague (1 ) apte à serrer la pièce, la bague étant équipée de plusieurs bras extensibles (2), ledit bras comportant des premiers moyens de serrage (14,11, 12), et un axe (17) apte à être inséré au travers de la bague et comportant des deuxièmes moyens de serrage (19, 20, 22, 23, 37), la pièce étant serrée sur la bague par coopération de la bague et de l'axe l'un avec l'autre suite à l'appui des premiers moyens contre les deuxièmes moyens de telle sorte qu'une extension du bras en direction opposée d'un axe d'allongement (53) de la bague est obtenue en fonction de la position de l'axe et de la bague l'un par rapport à l'autre.
Abstract:
An expandable wheel (10) for supporting an endless abrasive belt. The present invention relates more particularly to an expandable wheel (10) for supporting an endless abrasive belt, which includes an hub (12) having an axis and a plurality of wheel segments (30) engaged with the hub (12), where the hub (12) and the plurality of wheel segments (30) are adapted to rotate about the axis, and where the plurality of wheel segments (30) are movable between a first radial position and a second radial position.
Abstract:
Processes of chamfering and/or beveling an edge of a glass substrate of arbitrary shape using lasers are described herein. Two general methods to produce chamfers on glass substrates are the first method involves cutting the edge with the desired chamfer shape utilizing an ultra-short pulse laser that is followed by mechanical polishing with a compliant polishing wheel.
Abstract:
A wheel having an inflatable tyre (1) for releasable pressure engagement with an abrasive belt. The wheel includes a first hub assembly (2) sealingly engageable with a first axial opening (3) in one side of the tyre. A second hub assembly (4) is sealingly engageable with a second axial opening (5) on the other side of the tyre. The hub assemblies defining between them a fluid tight volume within the tyre. The wheel further including a valve having an inlet port (11) in fluid communication with the tyre a valve seat and at least one annular valve member resiliently biased into unidirectional sealing engagement with the seat, such that application of external pressure through the inlet port causes at least a portion of the valve member to resiliently deflect away from the valve seat to thereby open the valve and permit fluid communication with the fluid tight volume.
Abstract:
This invention relates to abrasive flap wheel that include hybrid fabrics. This invention also relates to methods of making and using said abrasive flap wheels. The claimed processes and systems related to the use and manufacturing of abrasive flaps are improved and cost effective.

Abstract:
Rolls (2) provided with a rubber layer are used in grinding machines (1). According to the present invention this layer consists of a number of sector-like units (9), the lower end of each unit (9) being inserted in a groove (3) in the surface of the roll. This avoids the whole layer having to be replaced, it being sufficient instead to replace one or more units (9).
