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.
In apparatus for forming a long wire rod coil from wire rod supplied in the form of overlapping non-concentrically disposed wire rod windings and utilizing a vertically displaceable centering mandrel having an upper end tapering to a point, a collecting device comprising wall means laterally defining a collecting space, means for supplying said wire rod windings into said collecting space, mutually oppositely disposed interceptor arm means pivotal into said collecting space for intercepting and temporarily supporting initial ones of said wire rod windings supplied to said collecting space, and mutually oppositely disposed pivotal arm means, each of said pivotal arm means being provided with a part-conical member, said pivotal arm means being pivotal toward said collecting space into a position wherein the part conical members of said pivotal arm means form a centrally disposed composite cone means adapted to accommodate therein said upper end of said centering mandrel and having a composite conical surface for centering said initial wire rod windings and guiding them onto said interceptor arm means, and means for pivoting said pivotal arm means and said interceptor arm means out of said collecting space to permit said initial windings collected on said interceptor arm means to drop along said mandrel toward its lower end and to enable further wire rod windings to be collected about said centering mandrel to complete formation of said coil.
A collecting device for producing long wire rod coils from overlapping non-concentric wire rod windings which are continuously supplied to the collecting device, the device co-operating with a centering mandrel which is vertically displaceable relatively to a collecting space in the device, and having controllable interceptor arms which are functionally associated with an upper tapering region of the mandrel, which temporarily intercept the initial downwardly falling wire rod windings produced from a desired length of wire rod to be coiled and which, by a sudden downward movement, release the temporarily collected wire windings for free fall along said mandrel toward its lower end, wherein oppositely disposed pivotal arms are provided in addition to the interceptor arms and arranged to be pivoted into the collecting space, each pivotal arm having at its free end one half of a conical surface, and said arms being pivotable into the collecting space wherein the halves of the conical surface cooperate to form a mandrel point independent of said vertically displaceable centering mandrel, and wherein furthermore control means are provided for the interceptor arms as well as for the pivotal arms forming the part-conical surfaces, and are operable in such a manner that shortly prior to the pivotal downward movement of the interceptor arms the pivotal arms are rotated downwardly to such extent that each half of the conical surface is located outside the vertical projection of the outer limits of the temporarily intercepted wire rod windings.
