Abstract
In a method for producing book covers, a folder, a booklet or the like having a blank (7) with at least one cover and a spine (3) connected thereto via at least one crease line (4, 5) and a bonding agent or binder for adhering pages or the like inserted in the book covers, folder, booklet or the like to the inside of the spine. To this end the binder is placed in the form of a strip (6') on a base (13) so that both longitudinal side edges of the strip are oriented between two creasing means (11, 12) projecting above the surface of the base, and the blank is aligned into a predetermined position above the base and creasing means, there also being a press means (14) for pressing the blank against the creasing means and strip to form the crease lines and to attach the strip to the inside of the spine. An apparatus for carying out the method comprises a base (9, 10) for the strip (6'), creasing means (11, 12) for orienting the strip, and a press means (14). In an alternative embodiment of the invention, the strip (6') is cut from a roll or sheet of material (16) by a cutting means (18) which also serves as base for the strip while the latter is pressed into adherence against the inside of the spine of the blank (7), which has been provided with the crease lines (4, 5) during a previous work operation.
