Abstract (en)
This invention has as object the structure of the bag partially transparent. <??>This structure includes a flat bottom from which there are developing walls with handles available to the user. <??>The peculiarity of this invention consists in the fact that the walls and the bottom come from the union and from the subsequent folding of two or more sheets that contain at least one sheet of material substantially transparent at sight and at least a sheet of papery material. Besides this aspect, these two or more sheets are united in a solid manner by the corresponding longitudinal borders through means of fixing. <??>The advantage is that the invention contains an equipment for the realisation of a structure of a bag partially transparent that contains two lines of movement for tapes of the above mentioned sheets, disposed coupled functionally speaking in a parallel manner for the longitudinal union of the above mentioned tapes. <??>Each of these two lines is made of a cylinder of support for a coil of tapes of sheets and from intermediate rolls that direct and stretch the tape unrolled by the bobbin. <??>There are present also means of advancement and synchronism of the relative advancement of each tape of each line of movement <??>Between these two lines there are disposed means of fixing for the union of the borders of the above mentioned contiguous tapes. <IMAGE>
