ABSTRACT:
A collecting device used in co-operation with a vertically displaceable centering mandrel for forming long coils from a given length of wire rod supplied in the form of overlapping non-concentric windings to a collecting space in the device comprises oppositely disposed interceptor arms which can be pivoted into the collecting space to intercept and temporarily store initial ones of the wire rod windings supplied to the space. Additionally oppositely disposed pivotal arms provided with part-conical members are arranged to be rotated into the collecting space in such manner that the part-conical members together form a centering cone for guiding and centring the initial windings and for accommodating the top of the centering mandrel. Means are provided for suddenly rotating all the arms outwardly to permit the collected windings to fall onto a collecting plate and the coil forming process to continue without interruption, the mandrel serving as a guide and centering means, and for rotating the arms back into their position in the collecting space upon completion of the coil to permit the next coil forming process to be started while the mandrel is lowered to permit lateral removal of the completed coil and thereafter returned to its raised position.
