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

Is a stitcher-folder with frontal trimmer enabling the production of high quality booklets and catalogues. The SUPER UNITÀ can be used either inline with the MAXIMA collators or for hand feeding.

STITCHING SECTION

Accepts up to 6 standard Hohner 48/5s (optional 52/8) stitching heads. Two stitching heads for flat staples are included with the machine. Also for loop stitching. Minimum distance between heads centers 50 mm. (mm 54 in case of the bigger ones).Simple converting from center to edge stitching. Wire spools (one given with each head) of 0,5 mm containing material for up to 80.000 staples each.
Double clinchers’ support always in axe with the heads when changing from stitching in the center to stitching on the edge. Four sides jogging into "C" form jogging squares that convey the set without any possibility of jam. The squares are pneumatically controlled. Pressure-free when the jogging the set. Only after stitching the set is then pressed by bearing onto the running transport belts (with adjustable speed) to get into the folding section. As the side gates are the same for the stitching and for the folding section, with only one touch we reach two adjustments.Anti jam detector at the entrance of the stitcher which stops the complete line in case of mistake.

FOLDING SECTION

The folding knife is electronically actuated from the bottom to the top and does not require any adjustment when changing size and thickness.
The fold is then created by mean of metal rolls with adjustable pressure and simmetric movement. Further transport is achieved by friction free double belts which convey the set through overdimensioned spring-loaded (400 Kg) calender rolls.

TRIMMING SECTION

The set is always under a full size clamping for the complete elimination of the inner air; the set is stopped and 12 self-compensating spring-loaded cylinders press the edge of the set (at about 100 Kg) before top and bottom knives are actuated. Blade with about 30° inclination and self-sharpening counterblade make a "scissors type" cut.
Max. cut thickness mm 6.
In case of sets with very delicate covers it is possible to select an electronic control which stops the double transport belts of the trimmer while the blade makes the cycle.

SHINGLE DELIVERY CONVEYOR

Variable speed shingle delivery conveyor with batching device for programmable shingle stream interruption. It can receive up to about 80 sets (depending on thickness of material).

TECHNICAL DATA:

Speed: Maximum speed in the maximum size mm 500 x 800 3.200 mechanical cycles/hour. Smaller sizes can run faster.
The actual production speed and the actual net output are dependent on size, paper quality, thickness, conditions of stock and other operating conditions.

Sheet size: Maximum 500 x 800 mm Minimum 210 x 300 mm
Maximum stitching thickness (about 30 sheets 80 g/m2) mm 3

Paper weight: From 50 up to 300 g/m2. To fold sheets over 200 g/m2 it’s suggestable to crease the material before collating.
To process sets made of sheets with characteristics out of the above mentioned data it’s suggestable to ask the manufacturer for a previous test.
