Introduction

PVC Flooring Roll Making Machine Line (also known as vinyl sheet flooring) is a continuous sheet flooring product made from PVC (polyvinyl chloride) resins with additives. It is lightweight, waterproof, and highly durable. This versatile flooring is widely used in residential, commercial, healthcare, educational, and public buildings.

Production Process:

A typical PVC Flooring Roll Making Machine Line follows these main steps:

• Material Mixing: PVC resin is blended with fillers, plasticizers, stabilizers and other additives in a high-speed mixer to form a homogeneous compound.
• Extrusion & Calendaring: The compound is fed into a twin-screw extruder where it is melted and pushed through a T-shaped die (T-die). The extruded melt then passes through a multi-roll calendar, which flattens and smooths it into a sheet of precise thickness.
• Embossing: If a textured surface is desired, an embossing roller imprints decorative or anti-slip patterns onto the warm sheet.
• Lamination: A printed design film (or color layer) and a clear wear-resistant layer are applied and laminated onto the PVC base sheet under heat and pressure. This bonds the layers into a single, finished vinyl sheet.
• Cooling: The laminated sheet moves over a long water-cooled conveyor or cooling table, solidifying the material and stabilizing its dimensions.
• Cutting & Winding: Finally, the cooled sheet is trimmed to width and cut to length (if needed) before being wound onto cores to form large rolls. These rolls are then ready for packaging and shipping.

Machine Components:

A PVC Flooring Roll Making Machine Line integrates the following main units:

• Twin-Screw Extruder: A heavy-duty conical twin-screw extruder thoroughly melts and mixes the PVC compound. Its design ensures uniform plasticization and high output.
• Calendar Unit: An adjustable multi-roll calendar (often three or four rolls) flattens and smooths the sheet. The gap between rolls sets the sheet thickness and surface finish.
• Embossing Station: One or more embossing rollers press patterns onto the sheet for decorative textures or functional anti-slip surfaces.
• Lamination System: An in-line laminating station applies the printed decorative film and transparent wear layer onto the heated PVC sheet, bonding all layers together in a single step.
• Cooling Table: A long, water-cooled conveyor brings the laminated vinyl to room temperature, ensuring it hardens and achieves final dimensional stability.
• Winder: An automatic winding unit rolls up the finished sheet into large coils. Tension control ensures tight, uniform rolls.
• Control Panel: A centralized PLC/HMI control cabinet manages the entire line. Operators can precisely monitor and adjust extrusion temperature, line speed, pressure, etc., for consistent production.

Advantages of PVC Flooring Lines:

• High Durability: PVC floors resist scratches, moisture, and heavy foot traffic. Their wear layer provides long service life.
• Design Versatility: A vast range of colors, patterns and textures can be printed or embossed, allowing custom aesthetics for any interior style.
• Recyclability: PVC is recyclable and modern formulations often use recycled content. This makes the flooring more environmentally friendly.
• Automation: Modern lines use automated feeding, gravimetric blenders, sensors and controls. One operator can oversee the process with minimal labor, ensuring consistent quality.
• Cost Efficiency: Continuous extrusion yields high throughput and low waste. PVC raw material is relatively inexpensive, and energy-efficient designs reduce operating costs.
