Abstract: 1. A method for making book covers using surface material (1) and cover pieces (2,3,4) that are to be glued onto it, characterized in that the desired number of cover pieces (2,3,4) are positioned in the desired location in clamp (14,15,16) that can be rotated around axis (13), and in that the pieces are supported in the desired position with the assistance of stoppers (10,11,12), and in that the cover pieces are rotated, while still in the clamp, around axis (13) onto the adhesive surface of surface material sheet (1) and are pressed onto it. 2. A method according to Claim 1, characterized in that the parts of surface material overlapping cover pieces (2,3,4) are folded onto the inner sides of the cover pieces. 3. A method according to claim 2, characterized in that folding is effected by sliding the edge of the cover piece along stopper surface (17) and subsequently through the gap formed between the mentioned surface (17) and a flexibly attached roll (18). 4. A method according to Claim 1, characterized in that the first cover piece is supported against a fixed stopper (10), and the others are placed in position using stoppers (11,12), which can be either movable or fixed in position in slots (8,9). 5. A method according to any of the preceding claims, characterized in that only two cover pieces (2,3) are positioned into the clamp or that the cover piece (4), when used, is of different material or of the same material of different thickness as the rest of the cover pieces (2,3). 6 A device to make book covers using surface material (1) and the desired number of cover pieces (2,3,4) that are to be glued onto it, so that the surface material equipped with an adhesive surface is on an essentially even surface, characterized in that it consists of a clamp (14,15,16) that can be rotated around axis (13) and is for the receipt of cover pieces (2,3,4), and stoppers (10,11,12) to assist in positioning the cover pieces in the desired position, whereupon the intention is to rotate the cover pieces thus positioned in place, still in the clamp, onto the surface of the surface material in order to attach them to it. 7. A device according to Claim 6, characterized in that it also includes stopper surface (17) and a flexibly attached roll (18) near surface (17), in which case a gap (19), corresponding approximately to the thickness of the book cover is left between surface (17) and roll (18). 8. A device according to Claim 6, characterized in that the clamp is formed of two plate surfaces (15,16), the distance between which can be advantageously adjusted. 9. A device according to Claim 8, characterized in that at least one of the plate surfaces (15,16) is equipped with a flexible covering on the inner surface. 10. A device according to Claim 7, characterized in that surface (17) and roll (18) are located in the back part of the device, whereupon the pushing of the cover onto the surface and between the surface and the roll is intended to be performed through the gap above the table surface (5) but under the part containing the stoppers (10-12). 11. A device according to Claim 6, characterized in that at least one of stoppers (10,11,12) is fixed in position, while the others can be either fixed or movable in the side direction. 12. A device according to any of the above Claims 6-11, characterized in that table (5) is a so-called illuminated table with markings that ease positioning or that the device includes a separate device which projects markings onto the surface of the table.
