By the way, in this comb machine, the lubrication between the respective gears and the lubrication between the gears and the support shaft are performed by the adjusting plate 6.7 and the end plate 26.
．． Lubricating oil is sealed in the space B formed by 27, and the lubricating oil is scraped up by the gears. However, it is particularly difficult to ensure that the backings 28 and 29 are oil-tight, and there is a problem in that leaked lubricating oil is transmitted to the comber and stains the fiber material.

[Object of the Invention] Accordingly, an object of the present invention is to provide a lubricating device for a rotary comb machine that prevents staining of fiber materials by lubricating oil.

[Development of the invention] According to the present invention, the opening 4 of a disc-shaped adjustment board with one end open for adjusting the degree of opening, which is pivotally supported on the machine frame of a rotary comb machine.
A member that is in sliding contact with the inner surface and to which the rotary comber is attached is connected to a disc-shaped end plate, a cylindrical part extending in the axial direction from the outer edge of the end plate, and a member that is radially inward from the edge of the cylindrical part. A housing band is formed in which a gear on the drive side or driven side of the rotary comber is housed in an oil-tight manner by the disk-shaped end plate portion extending in the direction.

[Operations and Effects of the Invention] Accordingly, the member to which the rotary comber is attached is formed in the housing body by the end plate part, the cylindrical part, and the end plate part, so that the gear on the drive side or the driven side of the rotary comber is oil-tight. As a result, even if the gears are lubricated by scraping up the lubricating oil from the gears, the lubricating oil will not leak out of the housing body, and as a result, the lubricating oil will leak to the =1-mer side and stain the fiber material. This can be reliably prevented.
