Reusable clamping spine for clamping a bundle of leaves (4), characterised in that the clamping spine (1) comprises two separate U-shaped profiles (2,3), each with two arms (6, 10) and a base (5, 9), more specifically a rigid undeformable spine (2) and a clamping profile (3) with rigid arms (10) whose free ends (12) can be moved towards one another flexibly in order to be able to clamp a bundle of leaves (4) that is introduced between the arms (10) of the clamping profile (3), whereby the clamping profile (3) can be inserted into the rigid spine (2) and can be taken out again for reuse, and whereby the form and dimensions of the two profiles (2, 3) are such that when inserting the clamping profile (3) into the spine (2) the free ends (12) of the arms (10) of the clamping profile (3) are pushed towards one another by the spine (2) in order to clamp a bundle of leaves (4). |
