50 deformación plástica, tanto en sentido transversal como en sentido longitudinal, no inferiores al 5%, y a continuación someterla en una estación 6 adecuada a las operaciones tradicionales de troquelado, marcaje del pliegue, plegado y encolado para formar una banda tubular y aplanada que comprende una pluralidad de pliegues 7 a lo largo de sus bordes longitudinales. 50 plastic deformation, both transversely and longitudinally, not less than 5%, and then subject it to a station 6 suitable for traditional die cutting, crease marking, folding and gluing to form a tubular and flattened band comprising a plurality of folds 7 along their longitudinal edges.

55 A continuación, se alimenta la banda tubular a una unidad de formación 8 que consiste en un rodillo 10 y que presenta en su superficie lateral uno o más relieves 12 que corresponden al diseño que se va a formar en la bolsa para la compra, y una matriz 14 enfrente del rodillo y realizada a partir de un material suave. 55 Next, the tubular band is fed to a forming unit 8 consisting of a roller 10 and having on its side surface one or more reliefs 12 corresponding to the design to be formed in the shopping bag, and a die 14 in front of the roller and made from a soft material.

Al pasar por la estación de formación, se proporciona a las dos superficies exteriores de la banda tubular aplanada 60 respectivamente una depresión 16 y una parte en resalte que corresponde al motivo del rodillo. When passing through the forming station, a depression 16 and a protruding part corresponding to the roller motif are provided to the two outer surfaces of the flattened tubular band 60 respectively.

A continuación, se corta la banda en una estación de corte 20 con el fin de formar piezas individuales que, en un extremo, son sometidas a la aplicación de las asas de soporte 28 y, en el otro extremo, son plegadas para formar la base 26 de la bolsa. Next, the band is cut at a cutting station 20 in order to form individual pieces that, at one end, are subjected to the application of the support handles 28 and, at the other end, are folded to form the base 26 of the bag.

65 La bolsa para la compra obtenida de este modo se alimenta a continuación a una estación de almacenaje 22, donde las bolsas pueden ser apiladas fácilmente una encima de otra gracias a la penetración conjunta de las deformaciones 16, 18 de las bolsas superpuestas. 65 The shopping bag obtained in this way is then fed to a storage station 22, where the bags can be easily stacked one on top of the other thanks to the joint penetration of the deformations 16, 18 of the overlapping bags.
