Abstract
A device for impaling loose leaves, such as a loose leaf binder (1) comprising two or more holding means (14) provided with for example rings or gripping fingers (10) fastened to one or more guide or guide members (5, 15). The holding means (14) of the device are mutually displaceable in one direction with respect to the individual guide member (5, 15) and detachably fastened thereto, said holding means (14) being preferably stepwise displaceable in said direction being the longitudinal direction of the loose leaves. The inventive device enables the manufacture of loose leaf binders without regard of which country or area the binder is to be used in. It is possible to move the individual rings or gripping fingers (10) with respect to each other as well as, if necessary, to provide the binder with extra rings or gripping fingers (10). The device also enables other equipment to be placed in the binder, such as pencil holders or holders for notepads or the like.
