Product Description 1. The Critical Role in RewindersA rewinder's primary function is to slit a large master roll (the parent roll) into multiple narrower rolls of specific widths and diameters, and then rewind them into finished rolls for shipment. This process is highly susceptible to alignment errors, which is why correction systems are indispensable.Key Applications & Challenges Solved:Precise Unwinding: The system guides the parent roll at the unwind station. This ensures that the web enters the slitting and rewinding section in a perfectly aligned manner. Misalignment here would be amplified through the process, causing:Telescoping: The layers of the finished roll protrude unevenly, making the roll resemble a telescope. This renders the roll unusable, as it cannot be loaded onto machinery for further conversion.Starring/Cinching: Internal stresses from mis-winding create radial defects, or "stars," within the roll, leading to web breaks and surface damage when unwound later.Poor Roll Hardness: Uneven tension from misalignment results in rolls that are either too soft (causing nesting and handling issues) or too hard (crushing the core or damaging the material).Post-Slitting Guidance: After the web is slit into multiple narrow strips, each strand must often be guided individually. Guiding systems ensure each separate web is perfectly positioned before being wound onto its own core. This is essential for maintaining a clean, straight edge on every finished roll.Surface/Roll Alignment at the Rewind Shaft: The most critical guidance point is often just before the rewinding drum or shaft. The system makes micro-adjustments to ensure each layer is wound precisely on top of the previous one, building a perfectly cylindrical, stable roll.Benefits of Correction Systems in Rewinders:Elimination of Product Waste: Prevents the production of telescoped or defective rolls that must be scrapped.Increased Operational Speed: Allows the rewinder to operate at high speeds without the risk of miswinding, maximizing throughput.Enhanced Downstream Performance: Produces high-quality rolls that run flawlessly on customer's printing, bag-making, or packaging equipment.Reduced Operator Intervention: Automates a process that would otherwise require constant manual monitoring and adjustment.2. The Critical Role in Inspection MachinesInspection machines are designed to scrutinize the material for defects-such as coating inconsistencies, pinholes, thickness variations, colour deviations, and contaminants-either 100% offline or inline. The accuracy of this inspection is entirely dependent on the stable, precise movement of the web.Key Applications & Challenges Solved:Stable Web Path for Accurate Defect Detection: The web must pass steadily under the inspection sensors (e.g., high-resolution CCD cameras, laser scanners, or ultrasonic sensors). Any lateral movement (weaving) or flutter can cause false positives (a good area flagged as a defect) or false negatives (a defect missed because it moved out of the sensor's field of view). The correction system locks the web into a fixed lateral position, guaranteeing inspection reliability.Maintaining Registration for Marking/Sheeting: When a defect is detected, the machine often marks its location (with an ink jet or label) or triggers a cutter to remove the defective section in a subsequent sheeting process. A stable web path ensured by the guiding system is crucial for this registration. The mark or cut must occur at the exact location of the defect; any web movement would cause the mark to be offset, making the defect impossible to find later.Precision Winding of Inspected Rolls: Similar to the rewinder, the inspection machine often rewinds the inspected material into a new roll. A guiding system is essential here to produce a high-quality, stable output roll for the next process step.Benefits of Correction Systems in Inspection Machines:Unmatched Inspection Accuracy: Dramatically reduces false calls and ensures genuine defects are reliably captured and recorded.Data Integrity: Provides trustworthy quality control data for process improvement and customer reporting.Value Addition: Allows producers to accurately grade and sell their material based on certified quality levels.Protection of Capital Investment: Ensures the high-tech, often expensive, inspection sensors operate under ideal conditions, maximizing their effectiveness and return on investment.System Components and TechnologyBoth rewinders and inspection machines typically employ edge guiding or line guiding systems. The choice depends on the material:Edge Guiding: Uses a sensor to track the physical edge of the web. Ideal for unprinted materials.Line Guiding: Uses a sensor to track a printed line or pattern. Essential for pre-printed materials where maintaining the print's alignment is critical.The system's components-sensor, controller, and actuator-work in a continuous closed-loop to make real-time, micron-level adjustments, adapting instantly to any material wander, tension variations, or splices.1. Q: When can I receive your quotation or reply?A: Within 1 hours if on our working time 08:30 a.m. to 17.30 pm. Monday to Saturday.Within 24 hours if weekend or holiday. lf you are urgent, welcome to contact us via WhatsApp/Wechat.2. Q: Is small order less than 100pcs accept?A: Sure, small order is welcome. The more quantities are, the better the price is.3. Q: Do you have a catalog or price list?A: Yes, we have a catalog but do not have a price list of all of our products.
