Abstract
Patente de Invenção: <B>"APARELHOS E MéTODOS PARA A TERMOFORMAçãO DE FOLHA DUPLA"<D>. Um método de termoformação de folha dupla é provido, no qual a costura (1) entre as folhas (7, 8) é aparada a partir da parte acabada, por meio de uma ação de cisalhamento entre bordas de cooperação das metades de molde (3, 4). Na forma preferida da invenção, uma metade de molde (4) é provida com uma região de dobra móvel (13), a qual se retrai sob uma pressão da outra metade de molde (3), para deixar uma borda da metade de molde (4) adjacente à cavidade de molde, a qual coopera com uma borda da cavidade de molde da outra metade de molde (3), para prover a ação de cisalhamento. A região de dobra móvel pode ser um elemento de dobra (13) suportado em um canal anular (14) por meio de uma mola pré-comprimida (15). A invenção permite um deslocamento plástico significativo do material na região de costura, para reforço de solda juntamente com o aparamento da costura da parte formada no molde em um processo de uma etapa.
