Abstract: Disclosed herein is a three-dimensional cellular light structure formed of continuous wire groups. In the cellular light structure, six orientational helical wire groups are intercrossed each other at 60 degrees or 120 degrees of angles in a three-dimensional space to thereby form a uniform pattern and having a good mechanical property such as strength, rigidity or the like. A method of mass-producing the structure in a cost-effective manner is also disclosed. The three-dimensional cellular light structure has a similar form to the Kagome truss. According to the manufacturing method of the three-dimensional cellular light structure of the present invention, a frame assembly consisting of rectangular frames and connection support bars is used, when the 1st, 2nd, 3rd, 4th, 5th and 6th-axis helical wires are assembled.

Abstract: In a method for manufacturing sawtooth card clothings and all-steel card clothings for processing textile fibers in a carding process, a sawtooth wire is produced by generating teeth on a wire blank sequentially behind one another in a longitudinal direction of the wire blank, wherein the teeth extend transversely to the longitudinal direction away from a base area. The sawtooth wire is subjected at least in the area of the teeth to a hardening process under exclusion of oxygen in the area of the sawtooth wire. A device for performing the method has a heating chamber having an inlet opening and an outlet opening for the sawtooth wire passing through the heating chamber. An arrangement for generating an inert gas atmosphere in the area of the sawtooth wire passing through the heating chamber is provided.

Abstract: A combination book binding machine with a plastic coil forming machine, whereby a plastic spiral coil is formed at a first raised temperature, then cut to a length sufficient for the plastic spiral coil to bind a book, cooled and then advanced toward a receiving coil conveyor of a coil binding machine, for binding the book with a plastic coil at the lowered cooled temperature. The binding machine and method for spirally binding a sheaf of papers into a book uses an adjustable speed drive to rotate the cooled flexible plastic spiral coil into respective holes in the book. The book has a plurality of holes in a row adjacent one edge of the book to receive the leading edge of the plastic spiral binding coils. A cylindrically shaped mandrel is spaced apart from a glidable block. The plastic pre-formed spiral binding coil is fed onto the mandrel from the distal end thereof, with the leading edge of the binding element facing and spaced apart from the book.

Abstract: A binding machine and method for spirally binding a sheaf of papers into a book uses an adjustable speed drive to rotate a flexible plastic spiral element into respective holes in the book. The book has a plurality of holes in a row adjacent one edge of the book to receive the leading edge of the spiral bonding elements. A cylindrically shaped mandrel is spaced apart from a glidable block. The plastic pre-formed spiral binding element is fed onto the mandrel from the distal end thereof, with the leading edge of the binding element facing and spaced apart from the book. A pair of leading edge spreaders, one of which has a guidance groove, engages the plastic spiral to spread its coils just enough to permit it to enter the successive holes of a sheaf to be bound. A trailing spreader at the opposite end insures that the last hole is accommodated with a portion of the spiral coil.
