Description of the Related Art For example, when a disk-shaped work made of aluminum, glass, ceramics or the like is polished by using a flat polishing machine such as a lapping machine, the work is held as shown in FIGS. Different carriers are used. This carrier 1 has a plurality of work holding holes 3 for holding a work 2 and is equipped with a gear 4 that meshes with a sun gear and an internal gear of a plane polishing device on the outer periphery. It is made of fiber reinforced plastics hardened with epoxy resin, and holds the work 2 in each holding hole 3 which is slightly thicker than the thickness of the carrier.

The work 12 fitted and held in the work holding hole 11 of the carrier 10 is shown in FIG.
Like the well-known carrier 1 shown in FIG. 1, it is provided with a plurality of work holding holes 11 and an outer peripheral gear (not shown) that meshes with the sun gear and the internal gear of the plane polishing device, and one drawing is provided. The carrier 10 is shown in cross section at the location of the hole 11.

る。Since the outer layer portions 13 and 13 rarely come into contact with the outer periphery of the chamfered work 12, any material having a reinforcing function can be used as the reinforcing fiber, for example, glass fiber. It may be hard and easily broken. On the other hand, since the middle layer portion 14 abuts on the outer circumference of the work 12, it is necessary to use a flexible reinforcing fiber that is unlikely to scratch the work 12, and as such a fiber, a polyester fiber may be used. It is suitable for holding aluminum discs.

１０に仕上げるものである。The carrier 10 can be manufactured by the following method. That is, as shown in FIG. 2, a plurality of middle-layer-impregnated sheets obtained by impregnating a sheet made of reinforcing fibers (for example, polyester fibers) suitable for use in the middle-layer portion 14 with a thermosetting resin such as a liquid epoxy resin. 14a
A plurality of outer layer impregnated sheets 13 obtained by similarly impregnating a thermosetting resin on a sheet made of reinforcing fibers (for example, glass fibers) suitable for use in the outer layer portion 13 on both upper and lower sides of the sheet.
a is polymerized, and these polymers are integrally molded by heat-pressing with hot plates 19 and 19 from both sides through a peeling film 16, a metal plate 17 for preventing deformation, and a cushion 18 for cushioning. The carrier 10 is cut into a desired shape and finished.

あっても不織布であっても良い。The thickness of the finished carrier 10 and the thicknesses of the outer layer portion 13 and the middle layer portion 14 can be adjusted by changing the thickness of each reinforcing fiber sheet and the number of superposed sheets, and the impregnated sheet for the middle layer. It is also possible to form the outer layer portions 13 and 13 with different thicknesses by making the number of sheets of the outer layer impregnated sheet 13a on both sides of 14a different from each other. The reinforcing fiber sheet may be woven or non-woven.

形成することもできる。The carrier 10 of the first embodiment uses a flexible reinforcing fiber for the middle layer 14, and the outer layer 13,
Although a rigid fiber having high strength is used for 13, the entire fiber can be formed of only a flexible fiber such as polyester fiber without using different types of reinforcing fibers.

に防ぐことができる。Similar to the outer layer portions 13 and 13 of the carrier 10 of the first embodiment, the outer layer portions 23 and 23 are optional reinforcing fibers having a reinforcing function capable of maintaining the strength required as a carrier, For example, it is formed by using glass fiber, while the middle layer portion 24 is formed by a soft material such as polyurethane resin, and preferably a cerium pad in which cerium is contained in polyurethane resin is used. It is preferably used for holding glass disks.
In this case, as shown in the figure, it is desirable that the middle layer portion 24 is slightly protruded inward from the outer layer portions 23, 23 in the work holding hole 21, so that the outer layer portion 23 when the middle layer portion 24 is compressed. It is possible to effectively prevent the workpiece 22 from coming into contact with the workpiece.

That is, as shown in FIG. 4, a sheet made of reinforcing fibers such as glass fibers is impregnated with a thermosetting resin such as a liquid epoxy resin on both upper and lower surfaces of a soft material sheet 24a such as a cerium pad forming the middle layer portion 24. The plurality of outer layer impregnated sheets 23a thus prepared are polymerized via a double-sided adhesive tape 25, and these polymers are heated from both sides via a release film 26, a metal plate 27 for preventing deformation, and a cushion 28 for cushioning. The carrier 10 is integrally molded by heat-pressing the plates 29, 29, and then cut into a desired shape to finish the carrier 10.
