Performance characteristics class 512
The Dürkopp Adler 512 is a CNC double lockstitching backtacker. The ex-
isting standard backtacking patterns are scalable and can be memorized
in this modified form. The machine is equipped with automatic sewing foot
raising, a thread cutter, a thread wiper, a needle thread clamp below the
sewing plate for a safe sewing start, and integrated DC direct drive includ-
ing a control panel.
Technical specifications
• The sewing unit is driven by a integrated positioning drive. Besides con-
trolling the sewing drive, a control unit also controls 2 step motors
required for the X and Y motions of the seam geometry.
• Clamp lifting is effected by a step motor.
• The maximum size of the sewing field is 40 mm in X direction (trans-
verse direction of arm) and 30 mm in Y direction (longitudinal direction
of arm).
• The machine head is oil-free. This removes the risk of oil soiling the
material to be sewed.
• The hook is lubricated by a wick lubricator from an oil tank in the opera-
tor's field of view.
• 50 pre-programmed backtacks are available. These standard patterns
can be temporarily modified (changes to overall length, overall width,
speed). When the machine is switched off, the modified values for the
last backtack to be used are kept until the machine is powered back on.
• 50 modified standard patterns can also be memorized.
• A maximum of 16,000 stitches can be memorized.
• 25 sequence programs, each with up to 30 sewing patterns per
sequence can be memorized.
• The accuracy of the coordinate input 0.1 mm.
• The machine has a bobbin thread counter and daily item counter.
• The arm shaft is directly driven by a brushless DC motor.
• Speeds of up to 3000 rpm can be set in 100 rpm steps.
