Embodiment Construction

[0031] The adhesive application device 100 has an adhesive application nozzle 1 which carries an adhesive application head 2 with a nozzle slot 3 through which adhesive 19 is delivered to the book block 22. 4 on the back of the book block. The book block 22 is here held by a gripper 23 and moved in the transport direction T past the adhesive application device 1 . Depending on the thickness 5 of the book block to be glued, the nozzle gap 3 is opened or closed by means of a first slide 6 . The slide has a defined cross section 7 and provides space for a defined amount of adhesive material 9 via a corresponding opening width 8 which corresponds to the book block thickness 5 .

[0032] By a premelter 18 - such as figure 1 As shown in , the melted bonding material 19 is pumped by means of the pump 20 via the hot hose 14 to the first closed valve 15 and back into the premelter via the hot hose 16 . As soon as the adhesive material is to be applied to the book back 5 , the valve ...

Abstract

The apparatus has an application nozzle (1) for applying adhesive to a book block spine (4). The application nozzle is line-connected to an adhesive supplying system. The application nozzle comprises a chamber (10) for providing adhesive and arranged adjacent to the nozzle opening, and another chamber (12) is arranged between a nozzle opening (3) and the supplying system. A slide (6) is arranged in a region of the former chamber for changing width (8) of the chamber, and another slide (11) is arranged in a region of another chamber for changing the volume (21) of the latter chamber. An independent claim is also included for a method for adapting an adhesive application nozzle.

Description

technical field [0001] The invention relates to a device for applying adhesive material, a method for adapting an adhesive material application nozzle and a further device for applying adhesive material. Background technique [0002] In the production of books by means of the glue binding process, the adhesive material is applied to the back of the book either by means of a roll applicator or alternatively by means of an applicator nozzle. The adhesive here is a dispersion adhesive, a melt adhesive or a dispersion-melt adhesive combination. Here, the adhesive polyurethane (abbreviation: PUR) has proven itself in recent years to be a fusion adhesive with particularly good tear strength of the pages and particularly advantageous properties for the 180° book block coating, the so-called lay-flat behavior. the result of. The bonding material can also be advantageously applied to poorer paper qualities, such as coated papers, where the percentage of coating constituents exceeds...
