Abstract: In order to avoid marking by the supporting surfaces in an endless belt for paper machines or the like with a number of helices consisting of opposing winding legs and headcurves joining these flanks together and into whose intermediary spaces the headcurves of the neighboring helix are forced to a degree that there develops between the two helices a range of overlapping into which a rod is inserted and in order to create the possibility for regulating the flow of air through the wire belt, at least the paper web-supporting winding legs of the helices are glued with a layer of fiber segments. Additionally, in such an endless belt permeability may be controlled by providing fiber segments on the winding legs and/or on the side areas adjacent the loop flanks.

Abstract: An endless sieve band or composite band for paper machines and the like, has a plurality of helixes composed of an elastic wire and each having two opposite winding legs and also two head curves connecting the winding legs with one another and having a predetermined wire diameter and wire width, wherein the helixes are arranged so that when the head curve of one of two neighboring helixes is inserted into an intermediate space of another of the two neighboring helixes an overlapping region is formed into which an insertion wire is introduced, and the winding legs of each of the helixes include a supporting winding leg which has flat supporting sufaces with a width exceeding the wire diameter or the wire width of the head curves.

Abstract: In a method and an arrangement for winding and forming helixes of elastic synthetic plastic and metal wire the wire is supplied from a wire supply device, windings are then wound from the wire so as to form straight winding legs connected by head curves, the windings are then separated to provide distances therebetween, the separated windings are widened in correspondence with the distances between them produced during the separation and the finished helixes are supplied to a helix supply device.

Abstract: Helixes are assembled into face structures by providing an initial helix which is stretched and retained on a work table, and a first helix which is attached to the initial helix, inserting into the first helix of a prestretched second helix by means of a joining tool and from a discharge conduit so that the second helix exits from the discharge conduit at an acute angle with respect to the first helix and moved along the latter connecting the second helix with the first helix by inserting an insert wire into the overlapping areas between the head arches of the first and second helixes, and displacing the thus finished face structure by a predetermined distance between insert wires in a timed sequence before a subsequent such inserting step for a further helix to be inserted into the second helix.
