Last year, Worldwide Foam shared the news of our 6th Fecken-Kirfel horizontal foam loop splitting machine.

Foam Loop Splitting Foam Skiving

In addition to being a leading distributor of XLPE foam buns, irradiated foam rolls, fire retardant foam XLPE, Armacell Foam, Zotefoam and more.

We are also a nation-wide converter of flexible foam materials.

Every product is custom-cut and shaped to your design specs by our materials engineers.

One year after sharing the news all of our foam loop splitting machines are hard at work providing the skiving of various types of foam for processors / manufacturers.

Industries and Product Types

  • Automotive / RV foam products
  • Foam seals and gaskets
  • Foam sheet and block
  • Marine foam products
  • Medical foam packaging
  • Sports foam products
  • Construction foam material
  • And more.

Splitting Thick Foam

When raw materials arrives too thick for our customers application, it becomes Worldwide Foam’s job to slim the foam down.

Foam Loop Splitting Machines Skiving

Our loop splitting equipment slices off clean, even planes from flexible materials like open cell foam and closed cell foam, neoprene, silicone and others.

With sharp blades and computer precision, our foam shiving techs cut large sheets that can be rolled up for later use, further shaped here in-house, or used as is.

Of course, similar to the rest of our foam products, all loop splitting and skiving is custom cut to fix the design specs of our customs.

That means OEM products are never “off-the-shelf”.

Custom Precision

When it comes to foam products, the possibilities are endless.

With our selection of high-quality foam types for various applications, you are sure to find the perfect foam solution for your needs.

When creating our foam products, we use our state-of-the-art F&K loop splitters to skive custom roll thicknesses and lengths unique to your equipment, application and customer demands.

You might be wondering, “How does Worldwide Foams skiving process happen”?

Before we take a look at how our foam skiving machines work, let’s define “skiving”.

Understanding Loop Splitting & Foam Skiving.

Skiving entails pushing a solid block of polyurethane foam through the blade of a knife.

The blade is actually a steel belt around 1mm (0.040″) thick with a very sharp edge, and is positioned horizontally above the machine table.

To help the blade cut smoother, it is looped over two drums that pull it perpendicular to the direction the foam block, or other material is moving.

These two motions help the blade slice through the material, shaving off the thickness required. And, thus the term foam loop splitting.

The skiving machine, sometimes called a continuous bandknife or a foam splitter, looks rather like a bandsaw laid down on its side.

Keeping the blade under tension ensures it doesn’t sag, so we can cut a block of foam into thin sheets quickly and efficiently.

Both the foam loop splitting & foam skiving technique are quite useful when producing specific thicknesses foam material.

Worldwide Foam Shiving & Loop Splitting Solutions

Every type of foam has its own unique properties in terms of density.

A heavier density denotes a foam that is stronger and more durable, but also hard to cut.

When it comes to cutting our densest materials, the foam skiving machine is the right tool for the job.

To cut our densest foam rubber, such as closed-cell foams and plastic foams, we employ the foam skiver.

This is the best option because it can handle cutting through the densest of materials without wear and tear while still offering a precise cut.

Longer rolls result in lower costs, faster speeds and improved sales dollars per hours worked.

Depending upon your die cut shape, size and the yield opportunities, we can split your bun material along the alternate dimension.

This allows us to optimize the OEM bun by choosing an orientation that works best for Worldwide Foam customers.

With the ability to slice sheets as thin as 1/16″ or as thick as 5″, it operates exclusively on a horizontal plane.

Because of the density of the materials cut with the skiver, the blade is substantial, measuring 3.3″ wide and .04″ thick.

Given the demands high-density materials place on a cutting machine, the foam skiving machine is incredibly powerful and constantly self-sharpens its blade.

It handles tougher materials while still maintaining its own blade making it one of the most valuable pieces of equipment we use.

You could also get a naturally clear and smooth surface of foam material with tight tolerance after skiving.

Advantages of Foam Skiving

  • No waste – Sawing, and for that matter, processes like water jet cutting, have a ‘kerf’ or thickness of material that is lost. Skiving has no kerf so there is never any waste. Obviously, this minimizes cost.
  • Dust free – Sawing is messy because the teeth carve away little chips of material. They stick to everything and can never be completely brushed off.
  • Smooth edges – Sawed edges are rough, which looks untidy and creates problems when sheets are put to use. Skiving polyurethane foam blocks avoids this problem, This means no secondary clean-up operations.
  • Close tolerances – A precision foam splitting machine, as we use at Worldwide Foam, keeps the blade tight and parallel to the machine bed. That ensures tight tolerances are maintained. Therefore customers receive sheets of consistent thickness.
  • Continuous resharpening – In material removal processes the cutting edge dulls with use, so the last piece cut has a different finish to the first piece. Skiving machines continuously resharpen the blade, so every sheet looks the same.

The machine is manually fed and can handle sheet widths up to 76″, with no limit in length.

For especially long sheets, the skiver is able to be fed from rollers.

The skiver requires some programming when setting desired sheet thicknesses. Best of all, the saw blade remains stationary once programmed.

Since the skiver can only cut horizontally, products are often trimmed down to size afterward on vertical saws, waterjet cutters, or die cutters.

Foam products produced on the skiver include high-density packaging, flotation devices, sports matting and padding.

Foam materials splitting & skiving technique refers to:

  • EVA ethylene vinyl acetate foam
  • PE polyethylene foam
  • SBR styrene butadiene foam rubber
  • CR neoprene foam rubber
  • EPDM ethylene propylene diene monomer foam rubber

Conclusion

Our foam skiving & splitting machines are highly efficient and accurate to shave raw material in sheet to any required thickness.

The skiving machinery are versatile to all sorts of foam material.  Splitting & skiving is often a transition phase for other process of foam fabrication.

Usually the foam sheet comes with a large thickness so we need to split them to wanted thickness.

Inside the skiving machine, there is a horizontal steel blade used to shave the foam sheet into two pieces.

Our technicians adjust the required thickness, then put the foam sheet horizontally crossing through the skiving machinery.

Finally, we can have the foam sheet or block in wanted thickness.

The foam sheet or block will be used in other foam fabrication process, such as die cutting and CNC contour cutting.

The K&F loop splitting machines bolts are maintained by ensuring proper bearing lubrication and torqued fasteners using a pneumatic torcgun.
