Abstract: Binding folder for binding a bundle of leaves (2), whereby this binding folder (1) comprises a cover (3) with a spine (5) and two endpapers (6), whereby in the spine (5) a U-shaped profile (4) from heat-conductive material is applied, whereby the U-shaped profile (4) comprises a base (7) and upright arms (8) and whereby in the U-shaped profile (4) a binding adhesive (9) in the form of a hotmelt adhesive is applied, characterised in that the U-shaped profile (4) in the spine (5) is applied by means of an assembly adhesive (11) between the upright arms (8) of the U-shaped profile (4) and the spine (5) of the cover (3), whereby this assembly adhesive (11) extends beyond the free edges (10) of the upright arms (8) and over these free edges (10).

Abstract: Method for binding a bundle of loose leaves or the like in a cover. The method includes the step of providing an end leaf that includes a fixing strip on a side edge, with the fixing strip partly fixed to the end leaf and provided with a strip of glue on a part of the fixing strip which is not fixed to the end leaf.
