1. Product Description

1.1 Short Description and Proper Use
The DÜRKOPP ADLER 558 is a double chain stitch buttonhole machine.
Buttonholes with or without eye and with or without taper bar can be sewn.
The buttonhole form is determined by 2 exchangeable disc cams with
corresponding knives. The upper disc cam determines the form of the eye. The disc
cam lying thereunder determines for buttonholes with taper bar the taper bar form
and the buttonhole length.
The smallest and largest buttonhole width for each sewing device (E no.) is
established by the position of the limit plate.
Pendulum swing of the needle bar from the rest position one-sided to the right
when sewing the right and one-sided to the left when sewing the left buttonhole
seam.
Automatic adaption of the upper cloth clamp pressure to differing material
thicknesses through spring-hangered clamp frame.
The safety devices do not have to be removed when tilting up the machine.
The combined finger-eye protection device increases safety.
It is held in the work position by springs.
The gas pressure spring aids tilting up and effects a sure, slow lowering. The stop
position makes an unhindered threading of the hook thread possible.
The machine is equipped with a central oil wick lubrication from 2 oil reservoirs
(the positions marked in red must also be oiled).
In the next chapter the individual sub-classes are described.
