Hinge bands 10 and 11 are made by welding sheets 3 and 4 either side of the strip 5, leaving an unwelded flexible band 16 between welds 10, 11 and 12<SP>1</SP> and the sheets are also welded along bands 14 at each end. In a modification, the hinge band welds 10, 11 are omitted, the strip 5 extending nearly up the bands 12<SP>1</SP> and the sheets 3, 4 acting as the hinge. The covers 1, 2 are of stiff plastic material and all sheets 1-4 may be ornamental, e.g. coloured or decoratively embossed. The strip 5 may be curved in cross-section to give a curved back binder.
