Description +

1. Optimization for Ultra-Thick Decorative Thread

Adler 204 Type Large Barrel Shuttle: It features dual extra-large barrel shuttle hooks specifically designed to handle extreme thread capacities and thicknesses.
Heavy Thread Capacity: It effortlessly accommodates ultra-thick braided and metric threads, including metric sizes up to 7, V415, T-400, 1300dx3, and Amann Serabraid 1400 T60.
Long Sewing Cycles: The large bobbin capacity reduces the frequency of bobbin changes, dramatically enhancing workshop productivity during extensive topstitching runs.

2. Specialized Post-Bed Design

Three-Dimensional Maneuverability: Unlike standard flatbed machines, the post-bed configuration provides superior clearance, access, and control.
Complex Geometry Handling: This is essential for navigating functional or decorative stitching on pre-shaped, 3D, or tubular items like car seat covers, sofas, armchairs, and luxury leather bags.

3. Superior Feeding and Climbing Power

Triple Feed Mechanism: Utilizing a synchronized system of a feed dog, needle feed, and walking foot top feed, the machine guarantees a completely constant stitch length without material slippage.
Exceptional Material Penetration: High needle penetration power ensures the machine pierces multi-layered thick spots or cross seams without skipping stitches.
10mm Foot Stroke: The sewing foot stroke transitions up to 10 mm, allowing it to safely "climb" over uneven material plies and overlapping transversal seams without stalling.

4. Aesthetics & Production Capabilities

Twin-Needle Seams: It produces perfectly parallel, striking double-needle decorative seams that elevate the luxury aesthetic of sofas, marine interiors, and aerospace upholstery.
Long Stitch Lengths: It supports bold, highly visible decorative and assembly stitches up to 14 mm in length.

5. Premium & Benefit-Driven

Engineered specifically to meet the rigorous demands of luxury automotive seating, armchair, and sofa manufacturers, the HighTex 204-370DP delivers unmatched efficiency and flawless stitch quality. This high-performance post-bed machine streamlines complex upholstery workflows with automated functions and precision handling. The Premium Features Included:

Compensating Presser Foot: Maintains even material contact across multi-layered steps.
