ABSTRACT:
A wire coiling apparatus with a recovery device for a coiled wire reel, including a coiler basket, formed of basket rods arranged on a baseplate which is drivable rotatably around a stationary vertical bearing, and a reel support mandrel that can be lowered upon and lifted off of this baseplate. The reel support mandrel includes a starplate insertable into recesses of the baseplate, and mandrel rods standing on the starplate. The free ends of the mandrel rods are connected with a guide dome and stand between the basket rods of the coiler basket in the inserted position of the reel support mandrel, in which position, the upper free ends of the basket rods are also connectable with the guide dome. The basket rods are fixedly inserted with their lower ends in the baseplate and their outer boundary lines face the wire reel windings, which lines are stressed by the wire reel windings during the coiling process, and extend to be slightly inclined inwards from bottom to top with respect to vertical. The mandrel rods are radially offset to such an extent with respect to the basket rods in the inserted position of the reel support mandrel that the wire reel windings do not contact the outer boundary lines of the mandrel rods. Herein the free ends of the basket rods are fixedly connected with centering bolts, which are insertable into centering recesses of the guide dome. The guide dome can be coupled with a retaining bearing, along its central axis, which bearing can be fixed so as to be stationary during the coiling operation.
