Heavy Duty Tyre Cord Centralizer offered comprise centralizing device that find use in tire-cord machines like dipping plant, let-off and wind-up stations, liner re-winder, calendars. Some of its features include comprising two joined axles bowed rolls for handing light/heavy duty processes as per application/fabric tension needs; a sensor for sensing both side fabric edges.

Double Jacketed Spiral Cooling Rollers are high-efficiency thermal control rollers engineered to provide uniform cooling of web materials during high-speed processing. These rollers feature a double-jacketed structure with an internal spiral baffle system that ensures even and controlled flow of cooling media (usually water or oil) across the entire roller surface. Ideal for applications that require rapid temperature control, these rollers enhance product quality and process stability.

Key Features:

• Construction: Robust mild steel or stainless steel core with double-layered cylindrical jackets

• Spiral Baffle Design: Internally welded spiral vanes ensure uniform coolant distribution and maximum heat exchange efficiency

• Precision Machining: Ground and polished surface for smooth web contact and minimal friction

• Material Options: Available in MS, SS304, SS316 with optional chrome or Teflon coating

• Leak-Proof Sealing: Precision welding and tested for high-pressure coolant flow without leakage

Technical Specifications:

• Roll Diameter: 100 mm to 500 mm (customizable)

• Face Length: 500 mm to 6000 mm or as required

• Cooling Media: Water, oil, or glycol-based fluids

• Surface Finish: Mirror-polished, chrome-plated, or Teflon-coated

• Connection Ports: Inlet and outlet for coolant with threaded or flanged fittings

• Max Operating Pressure: Up to 5 bar (varies by design)

• Temperature Range: Suitable for processes up to 180°C or more (based on media)

Applications:

• Plastic film and sheet extrusion lines

• Lamination and coating machines

• Rubber calendering and sheet cooling

• Paper and textile manufacturing

• Printing and embossing systems

Mild Steel Safety Chucks are mechanical devices used for secure and quick engagement of winding and unwinding shafts in roll-to-roll web processing machinery. These chucks provide a safe, reliable, and time-saving method for loading and unloading rolls, minimizing downtime and enhancing operator safety. Constructed from high-grade mild steel (MS), they are ideal for medium- to heavy-duty applications across a variety of industries.

Key Features:

• Material: Rugged Mild Steel construction for high strength and durability

• Quick Locking Mechanism: Allows rapid shaft engagement and disengagement without tools

• Flange or Foot Mounting: Available in both foot-mounted and flange-mounted versions

• Interchangeable Inserts: Accommodates different shaft end configurations (square, round, or customized)

• High Torque Handling: Designed to transmit torque efficiently for winding and unwinding operations

Technical Specifications:

• Bore Sizes: Available from 20 mm to 75 mm or customized

• Mounting Options: Foot-mounted or flange-mounted

• Load Capacity: Varies by size, suitable for medium and heavy rolls

• Material Finish: Machined and powder-coated or painted for corrosion resistance

• Insert Type: Replaceable inserts (standard square, triangle, or custom)

• Operating Mode: Manual open/close with spring-loaded safety lock

Applications:

• Paper and board processing machinery

• Flexible packaging and plastic film lines

• Textile and nonwoven fabric converting

• Slitting, rewinding, and laminating machines

• Printing and coating systems

Welcome to Bel Mark Industries Established in 1995 for manufacturing and exporting of Banana Bow Roller, Metallic Bow Roll, Rubber Bowed Roll, Slat Expander Rolls, Safety Chucks, Industrial Rollers, Scroll Rolls, Tyre Cord Centralizer, Air Shaft, Rubber Roller, etc.

Slat Expander Rolls, also known as Slatted Spreader Rolls or Metal Expander Rolls, are designed to remove wrinkles, spread webs, and separate layers of materials during the unwinding, processing, or rewinding stages. These rolls consist of a series of slats—typically made of aluminum or stainless steel—mounted over a rotating shaft with end rings and spacers to maintain uniform spacing and effective web control.

Key Features:

• Construction: Rigid build with multiple metal slats mounted over a rubber-covered or metallic shaft

• Material: Slats made from high-grade aluminum, stainless steel, or other non-corrosive metals

• Smooth Operation: Eliminates web wrinkles without stretching or damaging the material

• Non-slip Design: Ideal for delicate or slippery web materials where rubber expander rolls may not be suitable

• Balanced Performance: Dynamically balanced for high-speed operations with minimal vibration

Technical Specifications:

• Slat Material: Aluminum, SS304, SS316

• Roll Diameter: Typically 100 mm to 200 mm (customizable)

• Face Length: 300 mm to 6000 mm or as required

• Mounting Options: Foot mounting, flange mounting, or pedestal mounting

• Speed Range: Suitable for low to high-speed applications (up to 300 m/min or more)
