1. Product Description
1.1 Description of the Proper Use and Proper Application
The 506 is a robust, heavy-duty, curve-guided single needle doulble
saddle stitch short seam unit for seams of stitch type 301.
This short seam unit is designed for use in sewing heavy-weight fabric,
as well as thick and hard leather.
Thick and hard leathers find use in the sewing on of trim pieces, in the
sewing of buckle caps, tabs, suitcases, tarpaulins, knapsacks and
backpacks.
Heavy-weig ht fa br ic s a r e u sed i n t he sewing of heav y -d uty carrying
belts, car belts, as well as belts for aviation.
Generally only dry sewing material may be worked with this machine.
The material m ay b e n o t hi ck e r th an 16 mm wh en pre s sed to ge th er b y
the lowered cl am pi n g f ee t.
The machine m us t be op er a te d w i th ey e protection. The information to
be found print ed on the yellow s ign on the head cov er i s t o b e s t r i ctl y
adhered to.
The seam is generally made with synthetic sewing yarns with a
dimension of 30 /3 to 8/3. Those wi s hing to use other th reads must first
evaluate the d angers arising therefrom and, i f n ecessary, take safety
measures.
This heavy short seam unit may only be installed and operated in dry
and clean are as . If th e u ni t i s used in other areas , wh i c h a r e n ot dry
and clean, f urt he r, to be agreed upon, measur es m ay b ec o me
necessary (see EN 60204-3-1:1990).
We, as manufactu r er o f in dustrial sewi ng ma c hi n es , pre s um e t ha t t he
operating personnel working on our products have been given
instruction so that all normal operations and the dangers possibly
arising the ref r om c an be as sumed to be know n.
1.2 Short Description
Uniform Quality
The unit always produces a uniform seam formation.
The high thread tension necessary for the working of heavy materials
is achieved through a hinge d t hr e ad l eve r.
Direct Power Transmis si on
The power transmission from the motor to the arm shaft occurs via a
special V-belt. This results in a particularly strong perforating power
for the sewing of thick materials or multiple layers.
Interchangeable Curve Disks and Material Clamps
The different s ea m f ormations are de te rmi n ed by e as i ly
interchangeable curve disks.
The material guidance occur s vi a a p at t e rn c u r ve with two guide
curves. The difficult and time-consuming turning of heavy pieces of
material by the seamstress is thus unnecessary.
The transmis s i on of th e m ov e me nt to th e m aterial clamps o c cur s vi a
lever systems. By changing the lever multiplication the seam formation
sizes can be varied within certain limits.
All curve disks belonging to a stitch number range are interchangeable
among each ot he r.
Large Put-through Area and Large Placement Surface
The large put-through area allows the making of short seams far from
the edge of the material. A rolling-in of flexible sewing material is
possible. Th e c l o s ed wi d th ba s e p l at e o ffer s a l ar g e pl a cement surface

Pneumatic C la m p O pening
The stroke of the holder clamp is a maximum 20 mm. This stroke allows
the working of almost all sewable materials and leather thicknesses.
1.3 T e chnical D ata
Electric Thread Burning Device
The thread separator device separates the needle and underthread by
burning immediately at the top edge of the material. The synthetic
threads are melted together at the ends. The thus created hardening
hinders a loosening of the seam and a unthreading of the needle thread.
MICROCONTROL Controls
The complete control of the sewing unit occurs via a microcomputer. It
assumes the control tasks, monitors the sewing process and indicates
operator erro r s an d malfunctions .

ATTENTION !
Before commissioning it is essential that the number of stitches per
curve disk revolution be set at the internal DIP switch (b500) of the
controls appropriate to the curve disk used (see Part 4: Short
Description Multicontrol).
The starting of a sewing sequence is only possible with the head cover
and cover 3 for the hook area closed.
If the head cover or cover for the hook area is open all functions of the
controls are blocked.
