1 in fig3 is a non contact method of applying adhesive to the moving page 11 in this method a stationary adhesive applicator 16 sprays adhesive on one side of page 11 as it passes the applicator the adhesive applicator might be formed integrally with the print head 13 or might be located upstream or after the print head method 2 also applies adhesive to one side of the moving page 11 although this time using a contact method an adhesive applicator 16 is pivotally mounted about a fixed pivot point and is caused to move at a speed matching that at which the page 11 passes through the adhesive application station a reaction roller 30 comes into contact with the underside of page 11 as the adhesive applicator 16 applies adhesive to the page method 3 applies adhesive to both sides of a page 11 as it passes through the adhesive application station a pair of pivotally mounted adhesive applicators 16 move pivotally at a speed corresponding with that at which the page 11 passes through the adhesive application station they both come into contact with the page 11 and mutually counteract each other 39 s force component normal to the page 11 method 4 employs a pair of adhesive applicator rollers.
