Abstract
processo e equipamento para fabricar um corpo oco de plástico a partir de duas folhas. a presente invenção revela um processo para fabricar um corpo oco de plástico ao moldar duas folhas de plástico derretido em um molde que compreende duas cavidades, em que o dito processo compreende as etapas a seguir: a0 duas folhas de plástico derretido são fabricadas pela retirada de pelo menos uma corrente de plástico derretido e cortar transversalmente o mesmo; b) essas folhas são introduzidas entre as cavidades de molde; c) o molde é fechado e o corpo oco é fabricado ao se estabelecer um conformidade entre as duas folhas com as cavidades de molde; d) o corpo oco obtido dessa forma é removido do molde; e) todas as operações de a) a d) são repetidas a fim de fabricar outro corpo oco das duas folhas novas, caracterizado em que: antes, durante ou depois da operação de corte transversal, a porção inferior das duas folhas novas é resfriada ao usar um dispositivo específico que torna possível um resfriamento local das folhas na dita porção inferior.
