Meridian Products – Weber LCE-2-1350 Compact & Weber LCE-3-1350 wide belt sander
New Holland, PA 17557

At Meridian Products we produce high quality kitchen cabinet components. Our doors and drawer fronts can have solid wood raised panels or veneer panels. With the old technology wide belt sanders in our panel line we were required to do a lot of hand orbital sanding to get the quality level our customers needed. We identified our requirements and researched several brands and did some live demonstrations. After traveling to NY to demo the patented CBF system we chose to purchase two Weber machines, a three head calibration sander and a two head finish sander. The machines are well built and easy to operate. We have successfully reduced our sanding labor and are producing a more consistent finish.

Mr. Isaac B. Hayun, Long Island City, NY

I am building high end custom furniture and for this I needed the right machines for precise and quick results. I chose the Weber wide belt sander because it gives me the best flexibility for solid wood, veneer and lacquer/sealer sanding. With the patented Weber CBF system, I get almost no oscillation and the few marks left are removed by the patented Weber planetary brush head aggregate. The planetary head not only takes the marks away it also can sand deep into profiles and breaks the edges so that we do not need to sand by hand anymore.
I also purchased a tilting arbor MARTIN T27 Flex shaper, T45 thickness planer, T54 jointer and the T75 Prex dual-tilting sliding table saw. These machines are heavy duty and carry with them a great resale value…something that you do not see much anymore with industrial woodworking machinery.

Scott Slater – Weber Sander LCE 1350
Bespoken Woodworks, Sierra Madre, California

I have a cabinet shop in Southern California. I was in the market for a new sander and have had a few widebelt models in the past. The main reason that I was upgrading was that I needed a machine with 53” width and the ability to sand veneered panels without damage. I had previously owned a double head 43” sander with air platen and did not trust the machine when sanding veneered panels. It was always a job for hand sanding, which is expensive and time consuming.

The WEBER sander has a few features that make sanding difficult parts a breeze. First of all the machine has a segmented platen which uses 22 mm air cylinders to control the pressure of the platen. The machine also has a CBF head which creates very short sanding strokes (more on this later). When sanding veneer I want the machine to follow the variations in thickness in the panel, this is typically a very small variation but too much pressure on a high point will result in the veneer being sanded through. The WEBER uses rollers on the infeed to measure the work piece then turns on the segments in the platen based upon the settings I selected. I can control the pressure on all the edges protecting valuable materials. With a 180 grit belt I can run a veneered panel through the machine 4 times while sanding off a pencil mark on each pass before getting sand through. This was impossible with my old sander.

One place where the WEBER really shines is when doing finishing. When I have a flat piece that is going to be finished at the shop (most of my work is finished on site), I can apply the first coat of finish then set the sander up for lacquer sanding. I put in a 320 or 400 grit belt, and then run the part through. Absolutely no hand sanding is needed on the face. The part is simply cleaned off and the second coat is applied. I do this step 3 times and get exceptionally well-finished parts. The machine with variable speed on both the sanding heads and the conveyor belt is setup for lacquer sanding. The belt speed is slowed down, and the feed is sped up. With the CBF head the machine does very short sanding strokes, which does not load up the paper. The automatic belt cleaning during this program cleans the sandpaper. What happens is almost magical and the results are stunning.

The build quality of the WEBER is first class. The machine is made almost 100% at their factory in Bavaria Germany. WEBER makes metal sanding machines that are workhorses and uses this same heavy-duty construction in the wood line. The electronic parts are either Siemens or Toshiba and can be sourced overnight if the machine needs repairs (so far no issues with my sander).

I could not be happier with my purchase. I have had 2 other German sanders and neither one compares with the WEBER.

WEBER Cross sanding+

Automatic cross sanding machines for the skilled trades have a long tradition at WEBER. Cross sanding means that the first sanding is performed crosswise to the feed direction and subsequent finish sanding in lengthwise direction. The crisscrossing cutting motion offers advantages over multiple inclined or lengthwise sanding steps. The cross belt operates at a 90° angle perpendicular to the grain. As a result, the fibrous surface texture, which normally runs lengthwise, is divided into small sections and subsequent removal is simplified. This removal is subsequently carried out using one or more wide sanding belts. Due to the crisscrossing sanding directions, considerably fewer and shorter fibres remain on the surface.

WEBER X-Schliff+

Flexibility is becoming more and more important. For this reason, WEBER “X Schliff” offers all the sanding processes combined in a single station. The sanding station can be easily converted from wide belt to cross belt sanding. Thus, sanding processes can alternate between calibration, longitudinal or cross sanding or using WEBER CBF sanding technology. As today‘s requirements for various surfaces and lacquers call for different sequences of crosswise and lengthwise sanding, this new technology is able to respond to it. It enables lengthwise or crosswise final sanding, thus saving an additional machining station.

WEBER Texturing brushes+

Texturing brushes are used for texturing wood surfaces. The brushes remove softer areas from the wood surface and a ridged surface emerges. For coarse textures metal wire brushes are used, while brushes with abrasive plastic bristles or sanding brushes are used for subsequent smoothing.

Automatic workpiece thickness measurement+

The high quality of WEBER sanding technology is beyond question. But even more is demanded of an efficient and economically profitable sanding machine. Thus, the WEBER KSN convinces right down to the minutest detail with sophisticated solutions exceeding sanding alone.

WEBER Workpiece blow-off unit+

After sanding, the surfaces need dust removal. Mechanical solutions, such as dust brushes, cannot manage the work piece tolerances to a sufficient extent. The WEBER ES blow-off unit solves this task in a straightforward and elegant fashion. The workpieces are blown off by self-driven compressed air propellers arranged side by side which are only activated in the direct vicinity of the workpieces. This helps minimize compressed-air consumption.

WEBER Vacuum blower+

To ensure better and safer transport of the workpieces, the WEBER KSN has been equipped with a vacuum blower. To this effect, the conveyor belt and the transport table are perforated. A high-capacity blower produces a vacuum in the table body and draws the workpieces down to the conveyor belt. This enhances adhesion on the conveyor belt and the workpieces are transported through the machine precisely in the required position.
