Abstract

Il cestello (R1) di avvolgimento del filo, viene sostenuto assialmente da una struttura di contropunta (13) che si accoppia di precisione con la punta (5) assialmente cava e nella quale si inseriscono parti interne (123) della stessa contropunta, dotate di catenacci (24) che da parte di un otturatore (34) vengono portati da una posizione di riposo ad una posizione attiva con la quale dei ganci contrapposti di estremità (124-224) degli stessi catenacci cooperano con parti di ancoraggio (22-205) associate alla contropunta ed alla punta che in questo modo risultano collegate strutturalmente tra loro, senza possibilità di spostamenti assiali relativi. I cuscinetti del mandrino sono così preservati dalle sollecitazioni assiali che derivano dalla spinta del filo avvolto sulle ali del cestello ed il cestello stesso viene contenuto in modo controllato tra la punta e la contropunta, consentendo l'esecuzione di avvolgimenti precisi, del tipo spira-spira.The wire winding basket (R1) is axially supported by a tailstock structure (13) which precisely mates with the axially hollow tip (5) and into which internal parts (123) of the same tailstock are inserted, equipped with bolts (24) which by a shutter (34) are brought from a rest position to an active position with which opposite end hooks (124-224) of the same bolts cooperate with anchoring parts (22-205) associated with the tailstock and the tip which in this way are structurally connected to each other, without the possibility of relative axial displacements. The spindle bearings are thus preserved from the axial stresses deriving from the thrust of the wire wound on the wings of the basket and the basket itself is contained in a controlled way between the tip and the tailstock, allowing the execution of precise windings of the coil-coil type .
