Abstract

This record card receives strips of developed film or the like within one or more pockets. These are defined between transparent sheets that are flush with the sides of the card. Tabulating-type record card 1 has elongated aperture 2 surrounded by depressions or ledges 3 and 4, abraded, stamped or embossed in the front and rear sides 5 and 6, respectively, of the card. Transparent sheets 7 and 8 of MYLAR* or the like are mounted on 3 and 4 respectively. Sheet 7 is adhered about only three edges as in A. Sheet 8 is adhered about all four edges as shown in B, thus providing a pocket with an access opening along unadhered edge 9 of 7. Sheets 7 and 8 are ultrasonically welded or glued together along line 10 to divide the pocket into isolated subpockets or channels 11 and 12.

Film Strip Retaining Record Card

This record card receives strips of developed film or the like within one or more pockets. These are defined between transparent sheets that are flush with the sides of the card. Tabulating-type record card 1 has elongated aperture 2 surrounded by depressions or ledges 3 and 4, abraded, stamped or embossed in the front and rear sides 5 and 6, respectively, of the card. Transparent sheets 7 and 8 of MYLAR* or the like are mounted on 3 and 4 respectively. Sheet 7 is adhered about only three edges as in A. Sheet 8 is adhered about all four edges as shown in B, thus providing a pocket with an access opening along unadhered edge 9 of 7. Sheets 7 and 8 are ultrasonically welded or glued together along line 10 to divide the pocket into isolated subpockets or channels 11 and 12. These are only slightly wider than strips 13 and 14 of film so the strips are retained in parallel alignment within 11 and 12 without shifting or skewing. Ledges 3 and 4 and sheets 7 and 8 are of such depth and thickness, respectively, that 7 and 8 are perfectly flush with the respective sides 5 and 6 as in C. *Trademark of E. I. du Pont de Nemours and Co.
