Abstract: The instant invention is an improvement on a method of making wire coils comprising the steps of rolling a length of wire having a leading end and a trailing end and displacing the wire in a longitudinal travel direction and coiling the wire into succeeding overlapping loops and depositing same onto an upstream conveyor. The loops are transferred from the upstream conveyor to a downstream conveyor and are deposited from the downstream conveyor onto a centering device to form a coil thereon. The downstream conveyor is driven to move the loops at a generally constant slow transport speed but the upstream conveyor is driven to move the loops at a substantially faster transport speed when loops of a portion of the wire having one of the ends are being deposited on the upstream conveyor. Otherwise the upstream conveyor is driven at the same slow speed as the downstream conveyor so that the loops of the end portion will be spaced more in the travel direction than the other loops of the wire.

Separating fingers are movable into the chamber to temporarily interrupt the descent of rings therethrough, with the rings above the separating fingers being connected to the rings accumulated around the underlying mandrel by a single connecting strand. Pivotal arms, preferably sickle-shaped, are movable beneath the separating fingers across the path of ring descent. Each pivotal arm carries a shear blade which cooperates with a stationary shear blade located at the periphery of the path of ring descent.

Abstract: In a machine for manufacturing wire coils, wire is fed by a feeder and is shaped in a winding station to form a continuous helix the convolutions of which may adjoin each other or may be spaced predetermined distances apart. This continuous helix is cut by cutting means into wire coils having a predetermined length or number of convolutions. These coils may constitute springs or may preferably constitute electric resistance heating coils. To control the length of the wire coils, a sensing wheel is associated with the winding station and is driven by the wire and operates control means for controlling the cutting means in such a manner that the length of each severed coil is determined by the preset, measured wire length.
