Abstract

El presente documento describe un método para la reduccion del diámetro en el extremo abierto de recipientes, como por ejemplo, latas de bebida, en unaestacion de formacion de cuellos, que contribuye a evitar en gran medida la formacion deplieg ues en la lata. La estacion de formacion de cuellos incorporaun punzon de soporte deformable que se introduce en el extremo abierto de la lata. El punzon incorpora un manguito elastomérico, así como los mediosnecesarios para producir ladeformacio n lateral de dicho manguito, como por ejemplo, un actuador que establece un ajuste por interferencia con elmanguito. En la estacion de formacion de cuellos, la lata se inserta en un troquel que dispone de una zona de transicionque separa un orificio cilíndricoexterior de un orificio interior de diámetro reducido. Cuando el extremo superior de la lata es empujado más allá de la zona de transicion hasta elorificio interior, al objeto de reducir las dimensiones de laparte superior de la lata, el manguito se deforma de manera controlada, de tal modo que laparte lateral de dicho manguito queda encajada y soportada en la pared interna de la lata, empujándola contra la zona de transicion del troquel. Estaaccion desoporte y comp resion del material elastomérico contra la pared de la lata durante la operacion de reduccion del diámetro, permite evitar en granmedida la formacion de pliegues localizados.
