METHOD AND APPARATUS FOR WELDING AND CUTTING FOR THE PRODUCTION OF DISPOSABLE ABSORBENT SANITARY ARTICLES OF THE PRECLOSED TYPE THAT CAN BE WORN LIKE PANTS
A method for producing sanitary articles of the pre-closed pant type (10) comprising the steps of: - folding longitudinally in two a composite web (100), formed by a chain of blanks of absorbent sanitary products (10), which advance in a longitudinal direction (A), so as to form a continuous longitudinal portion of web and a discontinuous portion of web, the continuous portion comprising the waist regions, the discontinuous portion being basically constituted by the absorbent insert - welding (40) the continuous portion (38) of the web (100) with welding lines (13) that are transverse to the longitudinal direction of advance (A) so as to form the waist circumference and the openings for the legs (11) of the sanitary article (10) - conveying (50)- the composite web (100) through the welding station (40) maintaining the positive grip of the discontinuous parts (39) of said composite web (100) - feeding the cutting station (60) with said composite web (100), maintaining the positive grip of the discontinuous parts (39) of said composite web (100) and - cutting said composite web (100) to separate the individual sanitary articles (10) from one another.Linvention concerne un procédé de production darticles sanitaires (10) du type culotte préfermée comprenant les étapes consistant à : - plier longitudinalement en deux une bande composite (100), formée par une chaîne débauches de produits sanitaires absorbants (10), qui avancent dans une direction longitudinale (A), de façon à former une partie longitudinale continue de bande et une partie discontinue de bande, la partie continue comprenant les régions de taille, la partie discontinue étant constituée essentiellement de linsert absorbant - souder (40) la partie continue (38) de la bande (100) avec des lignes de soudage (13) qui sont transversales à la direction longitudinale de lavancement (A) de façon à former la circonférence de taille et les ouvertures pour les jambes (11) de larticle sanitaire (10) - transporter (50) l
