the associated with a 24 is a perspective view in the open position of another binder according to the associated with a 25 is a perspective view in the open position of a further binder according to the associated a With reference to the perspective view shown in 1 and the transverse section shown in the profiled support 1 is provided on the outer side with two parallel grooves 2 defining a back between a top board 4 and a bottom board and on the inner side with a locking formation the shape of a rounded bead 6 under the top board 4 and on the bottom board 5 with a locking formation in the shape of a groove for example of dovetail as With reference to the profiled support 1 comprises two parallel grooves 2 formed in the inner face of the reference to the profiled support 1 is provided with a single groove 2 which delimits on the hand a top 4 and on the other a back 3 fixed at right angles on the bottom board The top board 4 comprises a longitudinal groove Referring now to 5 and 6 the profiled support 1 comprises four parallel grooves which permits the binder closed on various thicknesses of sheets b giving different widths to the back With reference to each moulded binding post 11 is terminated at its lower extremity by a shouldered base 12 serving as a locking formation and adapted to slide in groove 7 and at its extremity comprises clip 13 serving as a locking formation which can be engaged on the bead 6 Referring now to the profiled binding post extruded for terminates in the same shouldered 12 and the same clip 13 as the binding post 11 shown in With reference to the binding post of the moulded type terminates at its upper portion in a formation in the form of a bead Referring now to the binding post 17 terminates at its upper portion in a clip 18 in the form of an unclosed whereof the gap constitutes a locking formation and which enables the user to Insert a new sheet without being obliged to remove all or some of loose The cooperation of the binder with the binding reference to 2 and the bindin posts 11 for example are mounted on the 5 by slidin their shoulders 12 into the groove It will be clear that in this way the number of binding posts required the perforations sheets are put in the desired By closing the the grooves open elastically and the bead 6 is elastically engaged in the clip 13 of each binding To open the it is only necessary to make the small effort necessary to open this On the other the groove 7 holds the shoulders 12 and keeps the posts 11 in now the binding poets 15 are mounted on the binder by sliding their shoulders 12 into the groove By closing the the bead 16 of the binding post is elastically engaged in the groove Θ of the top board With reference to 4 and by reason of the single groove open position of the binde the remains perpendicular to the bottom board the top board 4 being folded back externally to the With reference to in certain especially in order to receive leaves with multiple perforations at short spacing distances binding posts 19 may not be provided with a this being ensured by the complete binding posts With reference to the oonstant distance between the bindin posts 15 ensured by an appropriate Referring to in a profiled support 1 accordin to the is mounted a cover 33 which is at the same time wider and higher than the profiled support Referring to a profiled support 1 according to the invention is mounted in a and higher than the profiled support With reference to the cover 35 is wide and the same height as the profiled support the back 3 of which is riveted at 36 on the back 37 of the cover insufficientOCRQuality
