This Apex configuration combines Servo Gear Driven CI Flexo with 6+6 high-color double-side units—so cement, fertilizer and valve bag plants can print richer front/back graphics with embossing and folding on one Balanced Automation platform.
01 · 6+6 Colors
6+6 Front + Back
6 colors on the front and 6 on the back for brand-ready double-sided PP woven bag printing.
02 · Drive
Servo Gear Driven CI
Servo Gear Driven transmission keeps CI register and woven-web handling stable on double-sided PP woven bag jobs.

PP Woven Handling & Substrates
PP Woven Bag Focus
Unlike film packaging, PP woven bag performance is defined by fabric web tension and double-sided register. Apex Series is engineered for stable woven handling across PP woven, laminated woven and coated woven bags.
01
Closed-loop tension control
Independent tension zones continuously correct stretch and speed change on woven fabric webs.
02
Stable woven fabric handling
Stable web path control reduces elongation-related register drift on PP woven and laminated woven.
03
Edge guiding
Precise edge alignment keeps woven fabric tracking stable through continuous bag production runs.
04
Corona treatment compatibility
Supports corona-treated woven workflows for reliable ink wetting and adhesion on PP woven and laminated bags.
Applicable Woven Substrates

Cement & construction
Laminated Woven
Rice & grain packs
Coated Woven
Fertilizer & feed packs
Tubular Fabric

Laminated woven structures
Industrial Structure · Heavy-Duty Cast Frame
Built for Efficient Servo Gear PP Woven Production
Efficient Servo Gear Driven print quality on woven fabric webs depends on a rigid, proven frame. Apex Series central impression structures are machined on heavy-duty gantry centers to keep deflection under control during continuous PP woven bag production.
Mazak 5-Axis Machining Center
Central cylinder slides and core mounting frameworks are milled in a single-stage clamping setup for consistent CI drum alignment in continuous production.
Heavy-Duty Gantry Milling
Processes monolithic cast-iron wallboards (up to 120 mm thickness). Reduces structural vibration for stable multi-shift woven bag converting.
Production ROI
Apex Series improves production ROI through servo gear automation, stable long-run output and balanced CapEx for industrial PP woven bag production—keeping industrial reliability on woven fabric webs.

Apex Series 6+6 · High Color · Valve Bags Production
01 · Cement & Construction Bags
Woven fabric tension + double-side register
Maintains solid coverage and brand graphics on BOPP, PET and PE woven bag faces at speed. Suitable for cement, sand and construction woven bag converting where edge sharpness and color density must hold across long runs.
02 · Rice & Grain Bags
Stable print on laminated woven structures

Why Upgrade · Servo Gear Driven vs Conventional Gear Drive

Note: Master selection logic (flagship vs conventional) is not used on Apex pages. Apex owns the upgrade story: Servo Gear Driven vs Conventional Gear Drive (mechanical gear, no servo). Series cut: Apex = long-run Servo Gear Driven; King = Sleeve CI multi-SKU flexibility.
Apex vs King: Same speed class, different job mix — Apex = Servo Gear Driven · long-run stability · balanced automation; King = Sleeve CI · frequent changeover · multi-SKU flexibility. Choose King when SKU switches dominate; choose Apex when long-run woven bag output and ownership cost dominate.
