1. Product description

The

DÜRKOPP ADLER 577-1111

is an automatic double lockstitch
machine with bo tt om an d top feed for sew i ng bu tt on ho l es w i th two
straight bars.

Normal sewing mo de :
During the sewi n g pr oc e ss th e f ab ri c fa ce ( t he fa ce s e en ) ) is up .
The machine ca n b e s u pp l i ed i n t hree installat ion variants ( see on the

left ).

2. Normal use

The automatic sewing machine

DÜRKOPP ADLER 577-1111

has been
designed for sewing light to mi dd l e-h ea v y we i gh t m at eri a l , a s us e d i n
the apparel industry.

Such material c o ns is t s ge ne r al ly o f textile or sy nt he ti c f i bre s .
Furthermore, the machine lends itself for producing so-called technical
seams. In this case, the user must estimate any possible dangers
(contact dürkopp adler ag for help), Technical seams are seldom, but
they may be very versatile. Proper safety precautions, depending on
the result of suc h an es t i ma ti o n, mu s t b e t ak e n. G en er a l ly, only dry
material shou l d b e s ew n on thi s ma c hi n e. An d th e ma te r ial s ho ul d not
exceeded the thickness of

4 mm

when compresse d b y th e l o we red s ew i ng fo ot .

The material should not contain any hard objects, because otherwise it
would be necess a ry to pro te c t t he eye s du ri ng th e s e wi n g pr oc e ss ..
For the time bei n g, no such eye guard i s ava i l ab l e. Th e seams are
produced gene ral l y w i th th r ea ds u p to 65/2 Nm ( cott on - c ove r ed
synthetic threads or synthetic threads ) Before using any other threads
it is necessary, also in this case, to estimate the consequential
dangers and to take, if necessary, the respective safety measures.
This automat ic s ew i ng un i t s h ou l d b e i n s ta l led and operated on l y i n
dry and proper rooms. Otherwise, further precautions (to convene)
may be needed, ( si e he E N 6 02 04 -3- 1 :1 99 0 ) . We.m an uf ac t ur e rs of
industrial sewing machines, assume, that our machines will be
operated at le as t by a we l l tr a i ne d s t aff, k n ow i ng al l u s ua l con t ro l s an d

4.10 Thread tension

The machine head has been set i n t he fa c to r y fo r s ew i ng bu tt on ho l es
with flat bartacks and with raised lips.

Pre-tension

The pre-tension 4 is always active. It serves for stabilising the needle
thread. It sh ou l d b e s e t t o t he mi n i mu m v a l ue ( 5- 1 0 g ) . The
pre-tension 4 has scarcely any influence on the seam pattern.

Main tension

The main tensi o n 5 is active when sewing both buttonhole lips. But the
main tension 5 it is out of ac t i on wh en ba r ta ck i ng an d when cutting th e
threads.

Bartack tensi o n

The bartack tension 6 is opened only when cutt ing the threads. It is
remains clo s ed du ri ng th e e ntire remainin g s e wi n g p roc e s s .

Buttonhole lip tension

The buttonhole lip tension is produced jointly by the main tension

5

and by the bar ta c ki ng te ns i o n

6.

About 1/3 of the buttonhole lip tension

should be produced by the bartacking tension 6.

Adjustment

–

Thread the needle thread so that it does not pass through the main
tension 5.

–

Start the sewing process.

–

Adjust the bartacking tension 6 so that the max i m um po s s ibl e

process. But en s ure that the thread do es n ot fl a tter above the
pre-tension a nd th at i t i s n ot to r n.

–

Thread the ne ed l e a cc or d i ng to th e c h ap te r 4.1.

–

Start the sewing process according to the chapter 6.

–

Adjust the main tension 5 so that a satisfactory seam pattern is
obtained when sewing the buttonhole lips ( regularly raised lips ).

If the seam quali t y i s wo r se a ft er a th rea d c h an ge , p roc e ed to a
correction. Turn onl y th e ma i n te ns i o n 5.

Control

–

Use threads of di fferent colours for t hr e ad i ng th e n ee dl e an d t he
hook.

–

Carry out a sewing test.

When using two-colour threads, the colour of the needle thread in the
bartacks should be visible only from above.

5. Control unit and control panel

The present Manual describes only the function of the keys and the
change of parameters by the operator.

Operating Ins tr u c ti o ns o f t he mo to r ma nu fa c tu rer.

5.1 General

The control panel is used for programming the control unit and for
setting the r espective seam fu nc t i on s .
This is done partly directly by op erating the respective keys or by
changing the parameters.

The parameters are entered in the programming mode. The
parameters and th e assigned valu es a re presented by t he dis p l ay..

In order to avoid an y involuntary chages of the pre-set parameters, the
attendance of the control panel is subdivided into different levels (
operator, technician , f i tt er ) .

The operator has a direct access to its level.
For having an access to the other levels it is necessary to enter a code
number or it is necessary to press several keys simultaneously.

NOTE !

Do not turn the handwheel or the crank during the parameter change
on the operator level!

Reset

When the control unit is totally out of adjustment, the technician can,
by means of a Reset Function, reset all adjustment values to the state
existing at the moment of delivery.

The Reset Function is described in the Service Instructions.

5.3 Changing parameter values

NOTE !

It is absolutely necessary to complete a sewing cycle after the
parameter change. It is only then that the modified adjustment will be
definitely memorised. If no sewing is done, the new setting will be lost
by turning off th e m ai n sw i t ch!

For changing o r sw itching on and off th e p ar a me te r s pr e s s the keys

"P", "E", "+"

and

"-"

on the control panel.
The parameters that can be changed on the operator level are stated
in the following parameter list.

Calling up programming mode

–

Operate the key

.
The parameter, called up as last one, will appear.. If no parameter
has yet been c all e d u p after turning on th e m ai n sw i t ch, the display
will present

.

Selecting the desired parameter

–

Operate the key

"+"

or the key

"-"

displayed

–

The parameter value will be displayed after pressing the key

"E"

.

Changing the displayed parameter

–

For changing the parameter value or for switching on or off the
parameter function press the keys

"+"

or
