·         Needle distances from 6 – 30 mm can be selected, short conversion time from one to the other needle distance (approx. 30 min.)

·         Stepper motor driven center blade drive with extended flexibility in material use due to increased material flow. Stepper motor-controlled middle blade drive with increased flexibility in material use due to increased material passage and adjustable stroke for adaptation to the material thickness – reduced knife wear.

·         Reduced bobbin change due to double bobbin volume with large vertical hook (Ø = 26 mm). Large three-piece hook with capsule fan (Ø 26 mm) allows a reduced bobbin change due to double bobbin volume. A small vertical hook (0755 150064 / Ø = 22 mm) is available as an option.

·         New folder concept as modular system . The complete folder (1) consists of a folder ins ert (2) with sole (3). In order to reduce the costs of changing the folders, it is possible to change the folder ins ert or the sole only.

·         Optimized folder lowering – for tension free folder movement onto the material

·         The folder lowering is optimized by its horizontal movements before reaching the transport clamp. This improves the folding process of the piping strip and prevents the material from slipping during the folding process.

·         Quick-release fastener for changing the folders without tools

·         Quick-change connector (option) for quick replacement of heads with frequent needle distance changes

·         Maximum precision in the corner cuts due to easy-to adjust corner knife station option. Corner knife system (Option 755 337534). Maximum precision of straight corner incisions due to easily adjustable corner knife system, can be swivelled out for cleaning and maintenance.
