Abstract:
A method for casing a block of printed sheets into a cover in an adhesive binding machine, wherein the block has a back and opposite side surfaces defining a nominal block width and is transported in a block clamp having opposed clamp members that are spaced a distance corresponding to the nominal block width, said back and a portion of said side surfaces of the block together defining a spine that hangs out of the clamp with a spine width greater than the nominal block width, each said clamp transporting a respective block to a cover pressing-on station where the back of the block is positioned adjacent a back region of a respective cover having spaced apart score lines, and the block is connected to the cover by gluing at least a part of the spine to a portion of the cover, wherein the improvement comprises that, after glue has been applied to one of the spine or the cover but before the cover is connected to the spine, the spine width is decreased whereby the spine is aligned between the score lines of the cover such that the width of the block at the spine corresponds to the distance between the score lines of the cover.
