专利汇可以提供Method of manufacture and operation of ribbed member for treatment of fibrous suspensions专利检索，专利查询，专利分析的服务。并且The specification discloses a method of making, and operating, a ribbed member for the treatment of fibrous suspensions passed between the ribbed member and a corresponding ribbed member while the members rotate relatively. According to the disclosure the ribs are made from 1 1/2 to 5 times the normal heighth of ribs on such members, while the grooves between the members are partly filled with a synthetic material solidified in situ in the grooves. As the ribs wear down in operation, the height of the synthetic material in the grooves is reduced to restore the groove depth for efficient operation of the members.，下面是Method of manufacture and operation of ribbed member for treatment of fibrous suspensions专利的具体信息内容。

权利要求

1. The method of fabricating and operating an apparatus for the treatment of fibrous suspensions, the apparatus including a pair of relatively rotatable members having surfaces in substantially parallel spaced relation with ribs upstanding from each said surface in distributed relation and forming grooves therebetween, the tips of the ribs on the respective members passing closely by each other as the members rotate relatively and thereby effecting the treatment of fibrous suspension flowing between said members, the said method comprising: forming said ribs to a height within the range of about 1.5 to about 5.0 times the width of the ribs at the tips thereof, filling in the grooves between the ribs from the bottom of the grooves partway up to the tips of the ribs with a plastic filler material which is introduced into said grooves in a workable condition which and is caused to solidify in situ in said grooves, and reducing the height of the filler material in said grooves when the tips of said ribs wear down during use of the apparatus to the point the unfilled portion of the grooves is substantially diminished thereby to restore the unfilled portion of said grooves substantially to the original depth thereof.

2. The method according to claim 1, which includes incorporating a filler in said plastic material.

3. The method according to claim 1, which includes selecting said plastic material from the class of synthetic resins which includes epoxy resin and which becomes solidified by reason of a hardening agent added thereto and which is resistant to chemical attack.

4. The method according to claim 1 in which the said ribs are so distributed that the said grooves formed therebetween are nonuniform in respect of at least the length thereof.
