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.
Abstract: A sieve belt formed of a multiplicity of helices of thermosettable synthetic resin monofilament. Adjacent helices are meshed together so that overlapping windings form a channel through which a pintle-filament is passed. The helices are free of bias and torsion both before and after being assembled in the belt. After assembly the belt is stretched longitudinally and thermoset, causing the helix windings to penetrate slightly into the pintle-filament to tightly surround it with line contact, and to flatten the long legs of the oval windings between pintle-filaments.
