Abstract
LA INVENCION PRESENTA UN METODO DE ALLANAMIENTO PARA HOJAS UNIDAD HECHAS DE MATERIAL TERMOPLASTICO. LOS EXTREMOS SOLDADOS DE LAS HOJAS DE PLASTICO SE COLOCAN ENTRE DOS PLATINAS. LAS PLATINAS SE CALIENTAN PARA ELEVAR LA TEMPERATURA DEL MATERIAL DE PLASTICO EN UNA CANTIDAD SUFICIENTE PARA REBLANDECER EL MATERIAL DE PLASTICO SIN PERJUDICAR SU ESTRUCTURA MOLECULAR. LAS PLATINAS SE PRESIONAN ENTRE SI CON UNA PRESION SUFICIENTE MIENTRAS QUE SE APLICA CALOR HASTA QUE LAS HOJAS SEAN PRESIONADAS ENTRE SI SUMINISTRANDO UNA UNION RELATIVAMENTE LISA Y CONTINUA QUE TIENE UN GROSOR SIMILAR AL DE UNA HOJA SIMPLE. FINALMENTE, LAS PLATINAS SE ENFRIAN ENFRIANDO DE ESTA FORMA LAS HOJAS UNIDAS.
