GR-998 Heavy Duty Military Boots Sole Stitching Machine
GR-998 heavy duty sole stitching machine featuring C/D/J/H interchangeable horns.
Function
GR-998 sole stitching machine for heavy duty military boots and vulcanized shoes
Product Overview
The GR-998 is a premier high-capacity equipment developed for heavy-duty industrial footwear workshops. It is primarily utilized for translucent sole-to-upper lockstitch seaming of combat military boots, vulcanized shoes, and fashion leather footwear. By incorporating four specialized modular horn heads (C/D/J/H), the GR-998 covers a diverse array of manufacturing dimensions from children’s slippers to high-ankle tactical boots, ensuring an unbreakable, heavy-duty seam line for global military and fashion footwear contractors.
Advanced Features of GR-998 Sole Stitching Machine
- Four Interchangeable Horn Systems: Outfitted with C, D, J, and H horn adaptations to seamlessly switch production lines between traditional oxfords, canvas uppers, high boots, and child sizes.
- Heavy Rosin Thread Compatibility: The internal thread guides and tension arrays are uniquely optimized to feed multi-strand cotton, linen, and heavy rosin braided lines smoothly without snapping.
- Imported Haas CNC Accuracy: To sustain intense physical feedback when sewing 20mm thick layers, 100% of vital internal mechanics are fabricated via imported genuine US Haas CNC machine tools.
- Computerized Needle Control: Driven by a 750W electronic motor, operators maintain stepless variable speed control while the needle halting sequence is automated by internal computers.

FAQ About GR-998 Sole Stitching Machine
Q1: How do the four interchangeable C/D/J/H horns enhance production lines?
A1: Buying independent machinery for every single shoe type creates massive overhead costs. The GR-998 solves this via modular C, D, J, and H horn setups. Technicians can swap the mechanical horn attachment to alternate between standard leather dress shoes, low-cut fabric shoes, high-top military long boots, and tight children’s soles, all on one heavy-duty station.
Q2: Why is the GR-998 sole stitching machine highly recommended for military combat boots?
A2: Tactical military boots feature thick multi-layered soles and require water-resistant rosin multi-strand linen thread. Standard shoe machinery cannot feed sticky rosin thread or penetrate up to 20mm thicknesses without constant failure. The GR-998 is reinforced precisely to handle extreme multi-ply leather/rubber penetration and deliver reliable lockstitch tracking.
Q3: How does the electronic motor speed regulation operate under factory loads?
A3: Intricate leather upper margins demand careful material handling. Driven by a 750W electronic regulation motor, the operator maintains smooth, stepless speed adjustments via a variable foot pedal. This variable handling allows slower tracking around narrow toes and rapid stitching on straight margins, while needle positioning is computer-governed.
Q4: What are the structural benefits of US Haas CNC milling for industrial shoe machinery?
A4: Constant driving of heavy 180#/240# crochet needles through dense leather creates intense back-pressure and structural vibration. Because 100% of internal linkage parts are machined via original imported US Haas CNC installations, it guarantees tight geometric alignment tolerances, resulting in smooth cycles, less down-time, and long service lifespans.
