Stitch Options

This coverstitch machine has limited stitch options but is enough to provide professional results on your sewing projects. This Bernette B42 comes with 3 coverstitch options and one 2-thread chainstitch option. Coverstitch widths can be adjusted between 2.8mm and 5.6mm, so you can customize each stitch width for each project.

Fast Stitching Speed

A domestic coverstitch machine can stitch approximately 1,300 stitches per minute at an average speed, but speeds can vary from 1,000 to 1,500. And this Bernette B42 has an average sewing speed of 1,300 spm.

Simple Threading

Coverstitch machines are easier to thread when compared with a serger machine because they have only one looper rather than two. However, they are also more difficult to thread than regular sewing machines. The color-coded threading paths make threading the Bernette Funlock B42 easy and smooth.

Differential Feed Range

Coverstitch machines have two sets of feed dogs similar to serger machines. The differential feed feature allows you to adjust the relative speed of the feed dog to stretch or compress the fabric while stitching, allowing you to sew knits or lightweight fabric easier and faster.

The majority of coverstitch machines have a differential feed ratio range between 0.7 and 2.0. While some premium machines have a wider range, ranging from 0.5 to 2.25. Bernette Funlock B42 has a differential feed ratio between 0.6 to 2.o. You can make adjustments to the differential feed to give you greater control over fabrics that are difficult to manage, like slippery satins or delicate fabrics or laces.

Automatic Tension Features

Setting and manipulating the tension can be one of the most tedious parts of using a coverstitch machine or serger. Bernette Funlock B42 comes with a convenience auto-tension feature that automatically adjusts the tension for you when you select your stitch. It will also automatically reduce the thread tension when the lever is lifted, making it easy to remove your work from the machine.

Auto Drop Feed

This coverstitch machine will automatically release the feed dogs as soon as you lift the presser feet and will make it easy to take your work out of the machine when you are done.

Extended Throat Space

You can use the extra throat space to make larger projects easier. The Bernette Funlock B42 Funlock has a large workspace that is almost 4-inch in length, giving you ample space to handle larger projects such as custom curtains, drapes, or quilts. Clear LED lights are also included in this Bernette B42 to illuminate the entire area.
