Comparison Minerva M4000CL vs Minerva M3000CL

The maximum stitch length that the sewing machine can sew. This parameter is important for working with dense thick fabrics: the stronger the fabric, the longer the seam used for it. Accordingly, the longer the stitch ( 5 mm or more), the better the machine is suitable for working with similar fabrics.

The maximum stitch width performed by the sewing machine.

Most modern sewing machines can work not only with the simplest longitudinal seam (when the needle punctures go strictly one after the other) but also with seams that overlap a certain width — for example, zigzag and various decorative ones. And in overlockers, such features are generally available by definition.

The larger the maximum stitch width, the wider the possibilities of the machine to work with specific types of seams (ceteris paribus). An indicator up to 5 mm is typical mainly for entry-level devices, 5 – 7 mm — medium, and 7 mm or more — advanced.

The maximum sewing speed provided by the sewing machine. In the vast majority of models, this parameter can be adjusted, so that, if necessary, you can sew at a lower speed.

The more stitches per minute the machine makes, the higher its productivity, and the better it is suitable for large volumes of work. At the same time, note that high speed has a corresponding effect on price and power consumption, and it is not always required. Detailed recommendations on choosing the optimal speed for certain types of work can be found in special sources.
