Applications:

The vertical tenter-setting machine for shoe materials is designed for the production of automotive carpets, residential carpets, automotive interior components, shoe materials, and various other tenter-set products.

Main Specifications:

• Product width: 1500–2600 mm

• Heating temperature: Ambient to 220°C

• Heat source: Direct-fired natural gas, supplemented by thermal oil heat exchange and external hot air

• Line speed: 5–20 m/min

• Heat consumption: 200,000–400,000 kcal/section

• Product thickness: 1–15 mm

Key Features:

① Chain track: Rongfa-proprietary vertical chain track and vertical drive mechanism for automatic tentering and heat setting.

② Edge tracking: Far-infrared edge tracking with ball-screw adjustment; automatic pin-on and pin-off operations.

③ Process parameters: Speed, width, temperature, humidity, and airflow are all automatically controlled via an HMI (Human-Machine Interface).

④ High thermal efficiency: Oven temperature rises from ambient to 220°C within 30 minutes; features residual heat recovery for the oven, ensuring high efficiency and energy savings.

Production Process Flow:

Fabric unwinding → Fabric accumulation → Coating (adhesive application, backing, spraying, scraping, or dipping) → Tentering and heat setting → Hot pressing/smoothing → Air cooling → Fabric accumulation → Slitting and edge trimming → Fully automatic cutting and stacking → Or combined winding unit.
