Abstract
According to the inventive method for joining product parts by means of a glued spine, the juxtaposed edges of the stacked product parts which form the spine area (2) of the product in process are pre-treated with a tearing tool (4) e.g. with a rotating brush. The method is especially advantageous for joining multi-layer product parts with multi-layer folded edges to be joined, whereby the folded edges are torn up by the tearing tool (4) to a depth at least reaching the innermost layer. The inventive method is also applicable in the sense of stitching, for joining the individual layers of one single product part with one multi-layer folded edge.
