Abstract

PROCEDIMIENTO DE FABRICACION DE BOLSAS DE PELICULA DE MATERIAL PLASTICO CON ASAS, QUE POSEEN UN ELEMENTO DELANTERO Y OTRO TRASERO APROXIMADAMENTE RECTANGULARES, QUE SE UNEN ENTRE SI LATERALMENTE POR MEDIO DE ELEMENTOS LATERALES Y DE UNA TAPA PLEGADA EN LA PARTE SUPERIOR. LAS BOLSAS POSEEN ASAS, QUE SOBRESALEN POR ENCIMA DE LA TAPA PLEGADA. SU FABRICACION SE REALIZA ESENCIALMENTE EN LOS SIGUIENTES PASOS: EXTENSION DE UNA BANDA (26) DE PELICULA EN EL SENTIDO (V) DE DESPLAZAMIENTO DE LA BANDA; PLEGADO EN SENTIDO PERPENDICULAR A LA BANDA DE PELICULA DE DOS ASAS (36, 37) DE DOBLE CAPA, AL MISMO TIEMPO, QUE LAS ASAS SON, EN EL MISMO LADO DE LA BANDA (26), PARALELAS ENTRE SI Y PARALELAS A LA LINEA (Y-Y) CENTRAL DE LA BANDA DE PELICULA Y QUE SUS LINEAS DE PLEGADO SE EXTIENDEN EN EL SENTIDO (V); PLEGADO DEL ELEMENTO CENTRAL PARA FORMAR UN PLIEGUE (24) INTERIOR A LO LARGO DE LA LINEA (Y-Y); SUPERPOSICION DE LOS ELEMENTOS (9, 10) EXTERIORES PARA FORMAR UNA SEMIMANGUERA; UNION POR SOLDADURA DE LOS BORDES VERTICALES DE LOS ELEMENTOS (9, 10); TROQUELADO Y SOLDADURA DE UN ASA (36, 37); CORTE DE LA BANDA (26) A LA LONGITUD NECESARIA PARA UNA BOLSA.PROCEDURE FOR THE MANUFACTURE OF FILM BAGS OF PLASTIC MATERIAL WITH HANDLES, WHICH HAVE A FRONT AND A REAR ELEMENT, APPROXIMATELY RECTANGULAR, WHICH ARE JOINED BETWEEN SIDE BY SIDE ELEMENTS AND A FOLDED LID ON THE SIDE. THE BAGS HAVE HANDLES, THAT PROJECT OVER THE FOLDED LID. THEY ARE MANUFACTURED ESSENTIALLY IN THE FOLLOWING STEPS: EXTENSION OF A BAND (26) OF FILM IN THE DIRECTION (V) OF DISPLACEMENT OF THE BAND; FOLDED IN A PERPENDICULAR SENSE TO THE DOUBLE LAYER FILM BAND (36, 37), AT THE SAME TIME, THAT THE HANDS ARE, ON THE SAME SIDE OF THE BAND (26), PARALLEL BETWEEN AND PARALLEL TO THE LINE ( YY) CENTRAL OF THE FILM BAND AND THAT ITS FOLDING LINES EXTEND IN THE DIRECTION (V); FOLDING THE CENTRAL ELEMENT TO FORM AN INTERIOR FOLDING (24) ALONG THE LINE (Y-Y); OVERLAPPING THE OUTSIDE ELEMENTS (9, 10) TO FORM A SEMI-HINGE; JOINT BY WELDING THE VERTICAL EDGES OF THE ELEMENTS (9, 10); DIE CUTTING AND WELDING OF A HANDLE (36, 37); CUTTING THE BAND (26) TO THE NECESSARY LENGTH FOR A BAG.
