Abstract
Improvements in the manufacture of filing folders, essentially characterized by procedures as the first operation to cut the support sheet and the corresponding sheet of plastic material that has to constitute the cover, so that both have the same dimensions, except for what concerns to the width that will be slightly smaller that of the cover sheet, then proceeding to incorporate this on the support sheet by thermoelectric welding of the left edge of the said sheet leaving a free margin on the left of the support proceeding in a second operation to bend mechanically the left side of the support sheet to constitute a lateral flange, which is provided in the very operation of a reinforcing end bend and of a guide groove of angular section, inside of which the resulting flange fits the papers to file.
