Реферат: 173,081. Adams, D. A. Sept. 28, 1920. Post files; threaders; covers.-A file arranged for threading a binding-cord through the papers &c. for permanent binding comprises two tilting arches 6, Fig. 2, and corresponding fixed posts 3 slotted at the free end to receive the binding- cord 13, the stots 4A being longitudinal and entered by a lateral opening 4<B> disposed at an angle to the axis of the post. A detached barbed threader, normally housed in a pocket 11 in the cover member 1<A>, is used to draw the binding- cord in a loop through a central hole in the papers and the bottom plate 2 and cover member 1. For large sizes of sheet, the cord is first drawn through the central hole and then looped on the posts to form two loops 13<B>, 13<C>, Fig. 10, at the bottom when the papers are withdrawn from the posts, the loose ends of the cord being subseuqently passed through the loops, upwards over the back of the bound papers, under the cord 13 on the upper surface, downwards round the ends of the papers or through additional perforations 12A at the ends, and again through the two bottom loops, before tying. Cover members may be bound in with the papers.
