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.
Claims10
A method for producing a multi-page printed product having a glued spine, the method comprising the steps of
- providing a stack of one or more multi-page product parts, each product part having a spine area comprising a multilayer fold edge or a plurality of juxtaposed multilayer fold edges having an outermost and an innermost fold edge, the spine area having a length and a width,
- tearing the spine area of the multi layer fold edge or fold edges to the level of the innermost fold edges with a tearing or roughing tool, and
- applying adhesive to the torn spine area.
A device for producing multi-page printed products having a glued spine comprising the combination of
- a tearing or roughing tool;
- means for holding a stack of one or more multi-page product parts, each product part having a spine area comprising a multilayer fold edge or a plurality of juxtaposed multilayer fold edges having an outermost and an innermost fold edge,
- means for creating relative movement between said tearing or roughing tool and said holding means so that said tool acts on said spine area to a depth of said innermost fold edge;
- and
- means for applying an adhesive to said acted-on spine area.
