Description

Technical Field

[0001] The utility model relates to the technical field of needling processing equipment for felt blankets, and particularly relates to a felt sleeve needling device. Background Art

[0002] For the needling processing of a felt sleeve, the fibers of the felt sleeve are intertwined with each other through sharp needle tips, increasing the contact area and connection force between the fibers, thereby improving the strength and wear resistance of the felt sleeve.
