How to Measure and Cut Backslot Dimensions for Furniture Edge Banding Tape5

What is a Backslot?

A backslot is a groove cut into the back of an edge banding strip. It allows the strip to be inserted into the edge of the workpiece and held in place by a matching cutterhead on the edge bander machine. The backslot's dimensions are critical for achieving a secure and aesthetically pleasing bond.

Measuring Backslot Dimensions

There are two main factors to consider when measuring backslot dimensions: the thickness of the workpiece and the thickness of the edge banding tape. The backslot should be deep enough to accommodate the thickness of the workpiece plus the thickness of the tape, but not so deep that it weakens the edge of the workpiece.

For example, if you are using 1mm edge banding tape on a 19mm thick workpiece, the backslot should be 2mm deep. This will allow the tape to be fully inserted into the edge of the workpiece, but it will not weaken the edge.

Cutting Backslots

Once you have measured the backslot dimensions, you can cut the backslots using a backslot cutter. A backslot cutter is a specialized tool that is designed to create precise, uniform backslots. The cutter is typically mounted on a router or CNC machine.

When cutting backslots, it is important to use a sharp cutter and to feed the workpiece into the cutter slowly. This will help to prevent tear-out and other defects.

Tips for Cutting Backslots

Here are a few tips for cutting backslots:
Use a sharp cutter.
Feed the workpiece into the cutter slowly.
Make sure that the backslot is deep enough to accommodate the thickness of the workpiece plus the thickness of the edge banding tape.
Do not cut the backslot too deep, as this can weaken the edge of the workpiece.

Conclusion

Backslots are an important part of the edge banding process. By understanding the basics of backslot dimensions and cutting, you can ensure that your edge banding projects are successful.
