Product features
Flat and displacement-free assembly seams
The M-TYPE flatbed machines with basic mechanical functions and needle feed are equipped with sewing foot lift via knee lever and manually activated 2nd thread tension - this is the SENSITVE ECO equipment variant. Within this equipment variant, you can choose between a single needle and a twin needle machine, depending on the application.
Machines from the M-TYPE SENSITIVE series have been specially designed for sensitive applications with particularly fine materials in the light to medium-weight application range. The particularly wide range of applications in the field of “medium heavy sewing” leads the used machine technology to its limits in many cases. On the one hand these machines have to be able to process especially thick sewing materials with thick threads and large stitch lengths, on the other hand the same machines are expected to sew fine leather goods with very thin threads without tension puckering and without markings caused by the feeding components.
Technically, these machines are equipped with PTFE (teflon) coated throat plates, hook covers and attachment slides, which enable a trouble-free material feed during the sewing process, even when working with difficult-to feed materials like fine leather. The specially adapted sewing kinematics with reduced needle bar stroke guarantees perfect stitch formation in fine materials.
Your benefits at a glance
PTFE-coated hook covers and attachment slides for a trouble-free material feed
DLC-coated needle bars and feeding foot bars for nearly oil-free sewing
CTB bobbins for a constant bobbin thread tension
Cylindrical braking and lifting spring for reducing the bobbin lead after manual thread pulling (ECO)
Modified sewing kinematics for perfect stitch formation in fine materials
Sewing equipment with small needle holes and fine toothing for mark-free material transport
Available as 1- and 2-needle version
