Abstract: A spiral link belt has a plurality of plastic helices connected to one another which interlock in the manner of a slide fastener with neighboring helices. Overlapping widening arcs form a channel and pintle wires run through the channels and thereby connect the helices. Flat wires are inserted in the helices to reduce the air permeability of the spiral link belt. The flat wires are tilted relative to the plane of the spiral link belt. The flat wire running inside a helix can be wider than the smallest distance between the two helices connected to this helix. During production, the spiral link belt is thermoset only after the insertion of the flat wires.

Abstract: A double helix is formed from two partial helices each having the same winding direction and each having an oval cross-section with nearly straight upper and lower winding legs. The facing winding arcs of the two partial helices encircle each other. The upper winding legs of the partial helices extend at a different angle with respect to the longitudinal axis of the partial helices than the lower winding legs of the respective partial helix. The upper winding legs of one partial helix extend at the same angle with respect to the longitudinal axis as the lower winding legs of the other partial helix and vice versa.

Abstract: A safety coupling having a first drive/output element that is coupled with a second drive/output element via two disengageable coupling elements in the form of two-armed levers that are pivotably disposed on the second drive/output element. First lever arms of these levers are counterstops that in an engaged state of the coupling are disposed in the path of movement of stops that are disposed on the first drive/output element. Second lever arms are supported against a support plate that is shiftable against the force of a compression spring. When an unacceptably high torque occurs, the levers, as a result of forces acting upon the first lever arms, are first pivoted against the compression spring and shift the support plate. After a prescribed pivot angle has been exceeded, the second lever arms, under the effect of the compression spring, pivot further into an end position in which the first lever arms are disposed completely beyond the path of movement of the stops; the coupling is disengaged.

A plurality of helices consist of at least two components, the first component being disposed on the inside of the helix and the second component being disposed on the outside of the helix. Preferably, the second component which is disposed on the outside of the helix, is embedded in a groove in the first component.

Abstract: The spiral link belt consists of a multiplicity of synthetic resin helices in which the windings of one helix mesh with the windings of the adjacent helices in zipper fashion. Pintle wires are inserted into the channels formed by the meshing windings of each of two helices with the winding of the helices penetrating into the material of the pintle wires. The helices are of oval shape with heads at the winding arcs widened in the longitudinal direction of the helices. The width of the heads at the winding arcs is about one and one half to two times the diameter of the wire form which the helices are wound. The helix wire can also have a kidney-, U-or V- shaped cross section with a concave and a a convex side and can be wound so that the concave side faces inwardly or outwardly. The helices are flattened in the region of the winding arcs. Flattening is effected during thermosetting.

Abstract: A helix of great length wherein the structure is filled with a filler and wherein the structure is produced by a practice in which the helix structure and filler material are caused to rotate about each other upstream of the point of convergence, while the helix retains its orientation, and the speed of advance of the helix and the speed at which the filler material and helix are rotated are so adjusted that the helix is advanced by one winding during each rotation. The filler material is a braided tubing. A core preferably prevents the tubing from collapsing.

Abstract: A slide apparatus for joining ends of a belt of the type having a plurality of transverse interlocked spiral elements. The slide apparatus includes two tapered overlapping channels for the reception of the overlapping belt ends so that upon movement of the slide apparatus the overlap of the belt ends will be reduced. The tapered channels terminate in a common narrow channel having a width equal to the overlapped end spiral elements so that upon passage of the two belt ends from the narrow channel a spring biased pusher element will force the overlapped spiral elements into meshing engagement, wherein a pintle wire, inserted into the passage defined by the intermeshed spiral elements, connects the belt ends.
