–
The control panel with membrane keyboard that is able to display
graphics is fitted on the right side of the sewing head within easy
reach of the operator.
–
The following functions are operated via manual switches:
- Closing and opening the clamp
- Activating the sewing operation
- Quick stop with needle position "up"
–
Pneumatic cutting of the buttonhole.
–
Automatic adaptation of the cutting power for the buttonhole knife
dependent on the programmed buttonhole length.
–
Due to the vertically working cutting system support no follow-up
work required in case of different cutting block heights.
–
Vacuum extraction of the eyelet cut wastes
–
Central oil wick lubrication from two oil reservoirs.
–
Switch at the head cover for moving to the ideal position for
threading in.
–
Electronically controlled needle thread tension.
–
In case of needle thread breakage the needle thread monitor
interrupts the sewing cycle, the fabric clamps remain closed and
hold the workpiece which can be removed at the touch of a
button.
–
Covered, smooth design. The swivelling up of the automat is
supported by a gas-pressurized spring which also helps that the
machine head is swivelled back slowly.
–
The special design of the machine arm allows for a vertical
positioning of the fabric by using a different cloth detention device
(additional equipment).
Control
–
Counter indicating the number of buttonholes sewn on the display.
–
You can define up to 50 different buttonholes. Up to 25 buttonhole
sequences with up to 5 programmed buttonholes can be
memorized. One sequence may contain up to 9 different
buttonholes, every buttonhole can be 9 times repeated
consecutively within the sequence.
–
Integrated test and monitoring system "Multitest". This system
allows not only for a monitoring of the sewing process but also for
a quick testing of the input and output elements as well as of the
motor functions without additional measuring instruments.
–
By means of a setting provision on the display it is made possible
that the fabric support plate moves to the initial position of the
next buttonhole after releasing the workpiece. This allows for a
better view when positioning the fabric.
–
According to the buttonhole type the following parameters can be
set at the control:
- with or without eye
- tack type
(with taper tack, round tack, cross tack or no tack)
- max. speed: 2500 min
- buttonhole length
- cutting before or after sewing
- no cutting
- stitch distance
- form of eye
- electronic setting of the stitch row gauge (-1,0 mm to +0,5 mm)
- number of stitches in the eye
