Mold for, and method of, fabricating a perforated body and perforated
body for use as a friction spinning element
摘要:
The mold for producing a perforated body to be used as a friction spinning element comprises a mold body provided with throughpass holes extending between the opposite mold body surfaces. Each of the throughpass holes is filled with a non-conducting material. Thus, there can be simultaneously formed by electroforming at the opposite mold body surfaces two perforated bodies which may be of the same or different thickness. By virtue of the simultaneous fabrication of the two perforated bodies the openings or perforations thereof are exactly in alignment or coincident and, if desired, these two perforated bodies can be secured to one another in superposed orientation to form a composite friction spinning element, such as a friction spinning plate or disc or an endless friction spinning belt or band.
