Field of the Invention The present invention relates to a felt cylindrical body generally used for small-diameter rollers, and more particularly to a high-density felt cylindrical body suitable for use as a drive roller among aluminum-shaped conveying rollers.

ルが使用され始めている。2. Description of the Related Art In an aluminum processing plant, an extruded member immediately after exiting a die is first supported by a plurality of transport rollers.
After this, it is sent to a predetermined conveyor or post-processing equipment. The extruded shape is the melting point of aluminum (660 ° C) immediately after exiting the die.
Since the temperature is high and close to the surface of the transfer roller, the surface is damaged if it comes into direct contact with the surface of the transfer roller. Since this felt tube cannot be manufactured unless the shaft dimensions are unique to the needle punch machine, the product variation is low, the unit price is high, the tube cannot be partially replaced, and it is difficult to determine the appropriate replacement time. As felt rolls are beginning to be used.

廃棄処分のコストは相当に高い。A conventional felt roll is cut from a felt sheet into a disk shape to produce a laminated cylindrical body, so that a large amount of cut felt waste is generated from the sheet, which is uneconomical. There are various restrictions on the disposal of felt waste in order to prevent pollution, and the cost of disposal, whether incinerated or landfilled, is quite high.

If the compressive force is too strong, the central portion of the laminate will spread radially to form a barrel-shaped laminated cylinder, which is not desirable as a transport roller in shape, and is likely to collapse during use. Conversely, if you save the compression force to prevent barrel formation,
The hardness of the laminated cylindrical body is not sufficient, and the durability as a transport roller is inferior.
