Product features
Shift-free joining - thanks to bottom feed and variable top feed
Engineered for precision and performance, our high-speed zigzag seamers feature drop feed and variable top feed for shift-free joining and smooth, high-quality seams, even with delicate materials. The specialized subclass ensures accurate fullness application at the undercollar in the shoulder area. With low thread tension, minimal material displacement, and quiet, low-vibration operation, these machines deliver flawless results—even at top speed.
The 937 is available in three equipment variants:
ECO: Mechanical operation with knee lever presser foot, manual stitch length and width adjustment, and hand-operated seam locking. Can be used with external drives or the DACeco+ drive system.
ECO X: Adds an electropneumatic thread cutter and operates with the DACclassic drive system for increased efficiency and ease of use.
Classic: Includes pneumatic presser foot lift and automatic seam locking, offering maximum comfort and productivity for professional sewing environments.
Examples of use
