PFAFF 3734

Qualitx demand / work method

With the PFAFF 3734 sleeve setting machine, we offer a simple and affordable solution for achieving the perfectly sewn-in sleeve. The new PFAFF 3734 also uses the new thread tension regulation and the roller presser concept featured in the PFAFF 3834. It is equipped with the easy-to-use BDF-S5 control panel. For sewing in pre-gathered sleeves, pre-set fullness amounts can be activated via knee switch. This amounts ensures an optimum fitting of the pre-gathered sleeve into the arm hole. When sewing in non-pre-gathered sleeves, the user controls the required fullness using a second pedal. PFAFF 3734 guarantees good results even when processing difficult and sensitive fabrics.

New concept for the roller pressers - From lining up to heavy outer fabric

The coated roller presser comes as standard with the machine. Optionally, a cross-toothed roller presser is available, which significantly expands the machine's range of applications. This means that the machine can be switched from fine, delicate fabrics to coarse/heavy, hard fabrics in seconds.
