Operative mode:1.The sheet stops at the front lays2.A movable tablet and two devices of running
wheels pinch the sheet3.The camera detects the position of the sheet (on
the edge or on the print) and calculates the lateral displacement for good registration
4.The movable tablet adjusts the sheet’s position with a linear movement in both directions (os and oos)
5. Lateral sheet correction ( lateral tablet movement ) of ± 10 mm
6. Tolerated variation of printing is ± 1,5 mm7. Once lateral registration done, the camera
checks the new position of the sheet

Trend: Synthetic Materials
Latest Trends in Conversion of Folding Cartons
© BOBST SA - 2008SGu 06.06.2008 - 38 Compass Session
WHY Synthetic Materials Packaging:
To emphasize end products it is sometimes necessary to use unusual materials.
See through packaging gives more appeal and sense of the product inside.
It gives an effect of expensive / quality / niche product.

Challenges in Synthetic Materials Converting Process:
Die Cutting Cold processCreases compressed by rules get stiff Creases have bigger bending stressRough cutting edge due to rupture of materialsCrease on some materials changes colorDifficult to Fold and Glue

Applications can be realized by cold or hot die-cutting and creasing process. (even. at high frequencies)
Hot die-cutting and creasing process allows :Maintain crease effect (eliminate material memory/recoil effect)
Better quality creases
More flexible creases, easier to fold
To avoid lightening of the crease when folded (PVC)
A maximum facility of folding in the machine
NB: characteristics differ depending on the material
Hot die-cutting and creasing process requires specific cutting and folding methods

Plasma in the packaging industry
Openair® plasma systems employ the beam of ions and free electrons to :
1. Clean the surface and remove the contaminents (dust, moisture)
2. Increase the surface tension by activating the polymer structure (wettability)
3. Make the coatings and adhesives stick better

Metallised , UV varnished or laminated boxes savings :
Reduce the need for Mulitple adhesive gradesNo need of ‘’Milling’’ to remove top varnish/fil layer on glue flap.Reduce the glue investment by using cold glue ratherthan hotmelt
Only if one side carton stick to a polymere varnish or metallised laminationIf 2 sides are polymere, the hotmelt is required
If cold glue, the standard lower gluing unit can be usedPress : no UV varnish cut out = no special blanket(stripping blanket)Press : reduce the press down time for blanketadjustmentDiecutters : no need to have perforations on the glue flaps
