Abstract: A helical spring coupling for coupling together two helical spring ends, particularly two ends of a carrier in the form of a helical spring in a conveyor, comprises a coupler which is in engagement with both helical spring end portions. Over a certain distance the turns of the two helical spring end portions are turned coaxially into one another and lie one against the other in the axial direction. The turns fit into a helical groove formed in the coupler and whose pitch coincides with the pitch of the turns.The coupler may consist of an elongate core part having a helical rib provided on its outer peripheral surface, the groove being formed in the outer side of the rib. The two helical spring end portions may be fixed by one or more threaded bolts extending transversely through the coupler and pressing against the turns of the helical spring end portions in the groove.
