Winding Machines and Spooling Machines at a Glance

Alpha Converting are proud to present an at-a-glance overview of some of their range of winding and spooling machines.

  • Duplex Slitter Rewinders
    The ALPHATWIN duplex slitter rewinder is a robust centre rewinder with differential rewinding and fully automatic layon roll control for high quality winding. The cantilevered winding shafts are rigid during running yet provide for fast unloading and can easily be integrated with a variety of unloading systems. All models can be supplied with automatic knife positioning, fixed or auto setting laser core positioning and powered roll removal to improve productivity. The touch screen operator interface has simple recipe systems for multiple material types and slitting parameters.

  • Duplex HR Slitter Rewinders
    The ALPHATWIN HR duplex slitter rewinder is a robust centre rewinder with differential rewinding, and driven layon roll control for high quality winding to large diameters.

    The web is arranged for overhead delivery to keep the clean web away from potentially dirty floors while allowing easy access for visual inspection.

  • Individual Arm Slitter Rewinders
    The ALPHAWIND individual arm centre and centre surface winders provide the ultimate in winding of sensitive and thin films. Each roll is driven by its own servo motor for precise tension control with independent contact control for controlling roll density. The shaftless winding technology provides high speed unloading of the rolls either manually or, for larger rolls, directly onto roll carts. All models can be supplied with automatic knife positioning and powered or automatic arm positioning to improve productivity. The touch screen operator interface has simple recipe systems for multiple material types and slitting parameters.

  • Centre Surface Slitter Rewinders
    ALPHASHAFT centre surface winders for high speed winding of paper, nonwovens and films. The short web path from the slitting knives to the rewinds is common to all styles for accurate roll alignment. The surface drive rolls control the web tension precisely up to the rewinds for controlled rewinding tension up to the rewinds, even when winding narrow slit rolls.

  • Centre Slitter Rewinders
    The ALPHALAB slitter rewinder is a robust centre rewinder with cantilevered winding shafts suited to narrow width slitting and rewinding. The cantilevered winding shafts are rigid during running yet provide for fast unloading and can easily be integrated with a variety of unloading systems. The ALPHALAB can be supplied with twin differential rewinding shafts for sensitive films and foams or with single winding shaft suited to labelstock, papers and rotary die cutting applications. The touch screen operator interface has simple recipe systems for multiple material types and slitting parameters.

  • Shaftless Unwind Rewinders
    ALPHAREEL shaftless winders unwind and rewind a wide range of products without the need for shaft handling. The shaftless chucks are selected to suit the customer cores and may be air inflated, torque activated or mechanically expanding through end pressure. The shaftless winders are of heavy duty construction for long life.

  • Salvage Rewinders and Inspection
    ALPHASAVE salvage rewinders and inspection machines are available for a wide range of materials and roll sizes. The winders are supplied with manual web inspection, automatic web inspection or none depending on the purpose. Standard salvage (doctor) machines allow you to recover badly wound rolls or to remove faults identified in the roll. Inspection machines are supplied with bidirectional winding, whilst combining machines are optimised for loading of the small in-feed rolls for quick consolidation into one large roll.

  • Stand Alone Pancake Spoolers
    ALPHASPOOL stand alone spoolers efficiently convert pancake rolls of film and tapes to level wound spools or bobbins with a precise computer controlled traversing mechanism and sensitive tension control.

    The cantilevered unwind and rewind shafts provide quick roll change whilst the servo control systems ensure precise spooling. All Alpha spoolers are of heavy duty construction for long life.

  • Non-Stop Spooling Machines
    Alpha's spooling machines integrate with a wide range of tape and filament production lines. Non stop operation is normally achieved with integrated accumulators providing time for the operator to load new sores or spools. For high speed lines twin spoolers with automatic cut off can be supplied so that the tape only needs to be transferred from the finished spool to the new core before restarting.

  • Slit Spooling Machines
    Alpha's slit spoolers efficiently convert mini jumbo rolls of film and tapes to level wound spools or bobbins with a precise computer controlled traversing mechanism and sensitive tension control.

    The cantilevered unwind and rewind shafts provide quick roll change whilst the servo control systems ensure precise spooling. All Alpha spooling machines are of heavy duty construction for long life.

  • TWM Trim Winders
    ALPHATRIM TWM trim winders are designed to provide compact, high speed, efficient removal of trim from converting lines without the noise, dust and high cost of installation associated with many vacuum systems.

    The ALPHATRIM TWM is a stand-alone unit which does not need any integration with the host slitter. Each trim winder is driven by its own variable speed motor running under closed loop tension control from a precision pneumatic dancer, which automatically tracks the speed of the host slitter.

  • Pneumatic Trim Winders
    ALPHATRIM P winders have pneumatic powered traverse movement with a simple web path for quick threading. The traverse rate can be adjusted by the operator and automatically switches off when the line stops.

    Each trim winder is driven by its own variable speed motor running under closed loop tension control from a precision pneumatic dancer.

  • Automatic Slitter Rewinders
    ALPHAMATIC rewinders fully automate the winding process for a wide range of product types. The single position winder provides cycle times below that of many turret rewinders and the full cycle is independent of any operator involvement. Each automatic winder is custom engineered to provide optimum benefit to the production process.

    ALPHAMATIC machines can operate independently with their own unwind (off-line), or in line with a customer's continuous process.

  • Turret Slitter Rewinders
    Alpha's turret slitting rewinding machines offers a fully flexible option to automatic rewinding. Fully automated or semi- automated versions are available. Designed for use with paper, laminates or films the machine can be supplied with varying levels of automation. Standard tapeless (cinching) start at the beginning of wind helps to prevent adhesive contamination in subsequent processes. Automated delivery out to a banding and printing head and automated unload of the finished roll is all achieved without any input from the operator.

  • Cut to Length Machines
    ALPHACUT cut to length machines are supplied for cutting a wide range of materials to length. Each machine is custom manufactured to meet the customer's demands for length, accuracy and product handling. The cutting method is selected to provide the optimum cut quality, reliability or product handling. Cut to length machines can sheet wide films with subsequent placing for laminating to the primary product or cut profiled product direct from an extruder with automatic batching into bags or boxes running on conveyorised system.
