General Description
The machines of the
3950 Series
folder line are professional buckle folders
with an infeed width of up to 38 cm. They can be equipped with one or two fold units.
The fold units may be used in-line or at right angles.
There is a choice between suction- and flat pile feeders.
Folding Principle
The infeed rollers (1) and (2) transport the
sheet to be folded into the fold plate (3).
As soon as it comes up against the adjustable
stop (4), the sheet forms a buckle (5) because
the infeed rollers keep on moving.
The loop gets bigger until the sheet is seized
by rollers (2) and (6); this is where the actual
fold occurs.
The rollers draw the folded sheet from the fold
plate and the infeed rollers and move it on.
