Our highly sophisticated CNC-controlled fully automatic ‘Contour’ cutting machine enables the cutting of foam blocks into complicated shapes and sizes as per customers’ specific requirements. This system uses the CAD run software to cut almost all three dimensional shapes with a high degree of precision and repeatability while minimizing wastages. The circulating bandknife, which can be rotated by +/- 360°, even cuts sharp-edged corners. Equipped with a modern Windows-based CNC control system to easy and convenient use. The contour shaped production is used upholstered furniture and mattresses as well as in the packaging industry.

Split PU foam blocks efficiently into thin layers

Automatic circular splitting cut foam blocks fully automatically with thin layers and at high cutting speeds. The circular cutting application includes the upholstered furniture, mattress industry, packaging industry and technical materials.The optimized vacuum system holds the blocks and works together with the angle adjustment system to ensure precise cuts. These trimmed blocks are cut to specified thicknesses using CNC-based high precision ‘Slitting and Stacking Carousel’ cutting machines, from Fecken- Kirfel, Germany,

The continuous foam produced is cut into smaller blocks using the ‘guillotine’ type end-block cutting machine from Fecken- Kirfel, Germany. This machine is CNC-controlled and cuts the foam automatically at pre-determined lengths.The fully automatic traveling cut-off machine cuts Polyurethane foam directly behind the foaming line.
During the cutting process, the Travelling cutting unit is synchronized by incremental encoder with the foam block conveyor. Travelling cutting machine is used directly next of a continuous foaming line. Once the desired block length is reached, the cutting unit automatically lowers and the circulating bandknife cuts the foam block from top to bottom.

Precise cuts thanks to Teflon and grinding device

The Teflon-coated, pre-tensioned bondstrip ensures a consistently high cutting accuracy. The desired cutting height can be set using a limit switch. The bandknife grinding device’s two motorized grinding wheels continuously grind and sharpen the bandknife. This guarantees a flat and dust-free cutting surface.

The vertical cutting machine trims blocks and slabs made of Polyurethane foam with precision. The vertical machine allows the cutting of rectangular layers in the range of 5-500 mm. The machine features a stationary cutting unit, Materials are feed by a manual sliding table. The cross-welded bandknife allows cutting in two directions.
A bandknife grinding device with friction-driven grinding wheels guarantees consistently precise cutting results. The precision bandknife guidance with double rollers ensures that the bandknife always remains in the ideal position even when cutting foams with high densities. The machine features a motorized adjustment of the upper bandknife guide.

The Polyurethane foam material cylinder is fixed to a peeling mandrel and rotated via a motorized feed roller. The desired layer thickness can be easily set by using change gears or alternatively electronically. The Polyurethane material cylinder is moved vertically via lifting spindles, before being evenly fed into the circulating sharpened bandknife. The peeled foam can then be continually wound up by the next device.

Cut thin material layers with precision
The side spindle guides allow the material cylinder to be lowered smoothly and evenly. Hardened and ground bandknife guides ensure that the bandknife is guided with precision. An automatic bandknife adjustment (electronic eye) ensures that the bandknife is always in the perfect position. The band knife perfect location is guaranteeing a precise cutting result. The integrated grinding device to ensure a consistently high cutting quality.

A powerful solution for profiling large slab thicknesses up to 300 mm.The profile cutting machine ensures a consistent profile height maintained over the entire slab width. Its cast-iron construction and specially formed bandknife beams make the machine particularly robust. The convoluting profile rollers are extremely robust and have a particularly large diameter. They withstand high pressure and do not buckle, which ensures a consistent cutting quality and a cleaner cut. The bandknife is automatically adjusted. The ratio between the material, feed rollers, bandknife tip, and bandknife guidance remains constant. This means that a consistent cutting quality is achieved over the entire lifespan of the bandknife.
