PFAFF 3834

Qualitx demand / work method

The programmable sleeve setting machine PFAFF 3834 as a solution for the highest demands – "Sewing in sleeves like a professional tailor". A thread tension regulator has been developed for the new PFAFF 3834, which independently regulates the thread tension based on the material thickness. 360° monitoring! This feature ensures optimum stitch formation even when sew over cross seams and interlinings. The material can be processed with maximum accuracy by using the roller presser (which moves close to the needle). Optimal sewing with a clear view of the sewing material is ensured. The PFAFF 3834 guarantees smooth seams and an even stitch appearance, especially when processing sensitive and difficult fabrics.

• Very good view of the material in the sewing area, due to optimized feed concept via wheel feed und driven roller foot 
• Extreme wide range of applications - from lining up to heavy outer fabric 
• Separately adjustable feed ratio for the top and bottom feed system (by stepping motor) for consistent application of fullness 
• No compressed-air connection required 
• Accurate and consistent stitch formation and constant stitch length 
• Stitch-length and fullness amounts in increments of 1/10 mm 
• (within the seam areas the stitch length can be changed)
• Teach in seam programming - size is free selectable
• Mirrored seam for alternating left or right sleeve
• By entering the grading values the sewing programs for all sizes are called up automatically

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.
