After printing, only two operations for finishing:

To collate booklets up to 100 pages from format 50x100 to 245x350 mm.
It is easy to mix different kind of colours, format and thickness at the same cost.

GENERAL MACHINE DATA SFT2

SFT2 STITCHING-FOLDING-TRIMMING

THE SFT2 is an automatic stitcher and folder with a frontal trimmer enabling high production of top quality booklets and catalogues. It can be used either with MAXIMA collators inline or separately with manual feeding.

 

STITCHING SECTION
Up to 5 stitching heads for flat and loop staples.
Standard version equipped with 2 stitching heads Hohner and 2 wire-spools (mm 0,5) for 80.000 staples each approx.
Double clinchers’ supports moving with the heads when changing from central to edge stitching.
Two side (longitudinal) jogging squares with a “C” section convey the set preventing from any material jam stop.
Transversal jogging is obtained through elettro-magnetic controlled gates.
The set is “pressure free” during jogging step and only after the
stitching cycle is completed, it is transferred to the folding section, with running belt at a variable speed.
Stitching and folding work on the same axe, so the that side gates in the two sections need only one adjustment.
A detector prevents any material jam before the set is transferred to the stitcher.

FOLDING SECTION
The folding knife is adjustable (height) without any tools.
This operation is done out of the folding unit without opening the protection cover.
Two small rollers, located just under the folding rollers, put the set in the perfect position for folding.
The bigger diameter of the folding rollers allows to press all kind of material thickness.
Folding rollers are self centering when changing set thickness.
Double belts transport the set without any frictions into high spring-loaded (kg 400) calender rolls, from which the set is pushed out to the trimming section.

TRIMMING SECTION
The set is kept under pressure to skip inside air, then it stops under the trimming section and pressed on the edge by 11 self-compensating spring-loaded cylinders (kg 100).
A 30° inclinated blade and a self-sharpening counterblade unable a “scissor” cut (Max thickness mm 5). In case of coated or any special surface, transport belts can be stopped during the cut cycle to avoid scratches.

SHINGLING DELIVERY CONVEYOR
Variable speed shingling delivery conveyor, with pre-selector for shingling stream interruption.
It can store up to 80 sets (depending on material thickness).

GENERAL MACHINE DATA SFT3

The SFT3 is a completely automatic stitcher - folder - trimmer for top quality productions with central control of the machine . It can be used either with MAXIMA collators inline or separately with manual feeding.
The material is transported by a double rotary PVC finger belt with a steel structure in the stitching and folding sections.
With the touch screen panel adjustments are possible without
stopping the machine.
The machine PLC can store up to 5 jobs’ data.

TOUCH SCREEN
With the SFT3 you can change, directly from the touch screen monitor, every format.
Pushing the memorized program number, the SFT3 will change the position of each square very quickly
and it will be ready to start working.
Advantages:
• Minimum downtime to set up the machine and fast changing format.
• Adjustments possible when machine is running.
• Much lower noise level.

STITCHING SECTION


Up to 5 stitching heads for flat and loop staples.
Standard version equipped with 2 stitching heads and 2 wire-spools (mm 0,5).
