- Film-only, pad, u-board and tray solutions
- Single stream and multi-stream capabilities
- Simple and repeatable changeovers
- Side mounted film stand assures proper ergonomics and adds convenience for film loading and splicing
- Flexible servo driven wrapping wand provides exceptional film control
- Revolutionary patented heat tunnel uses advanced heat and airflow management, delivering tightly wrapped packages for maximum package integrity and appearance
Eliminates soft bottle bridging and removes gaps to ensure pack pattern accuracy and continuous product flow.
- Modulated conveyor speeds control product surge and aid product flow
- Tool-less clamps and pinned lane guide adjustments for stable operation and quick, accurate changeovers
- Single clamp design at each cross member quickly locks in multiple lanes
Fast, repeatable changeover feature offers multiple enhancements.
Changeover time – significantly reduces time to less than 5 minutes (time of changeover is dependent on extent of changeover)
Repeatability – rail positions are recipe-driven and locked in place to within +/- 1/32″
Flexibility – ability to place lanes where desired as opposed to centerline or fixed side adjustments and more customer options for generating product-specific recipes
Durability – infeed rail’s holding force can withstand high product pressure
Ergonomics – minimizing manual adjustments maximizes efficiency and promotes safety in the work environment
The single nip roller and vacuum belt film delivery combine with a servo driven cutting knife to provide efficient operation.
Film Cutting & Placement
Variable Path Metering
Innovations to our patented Slipstream™ pinless metering system incorporate variable path registration bar technology and slip sheet technology.
- Gently groups and meters products into the machine
- Dynamic variable path motion registers products with less pressure and interruption to product flow
Slipstream™ MS Mid-Speed Pinless Metering
Offers highly accurate product registration for slower speed applications.
- Provides slip sheet grouping of pack patterns for tray packing
- Run bottled, cartoned, canned and other products without the use of tampers or escapement pins
- Tool-less changeovers and preprogrammed settings increase productivity
Variable Path Metering
The ergonomically designed automatic film splicer delivers precise print registration and heat splicing, reducing critical machine downtime. The easy-access side film stand enables operators to stage clear or printed film, at their convenience, while the machine is running. Staging during operation maximizes production time and minimizes the occurrence of empty film faults. Once the film is staged, no operator attention is needed for splicing. Splicing occurs automatically; providing operators considerable flexibility with work load.
This option is a great addition to a new Contour™ Shrink Wrap System. Its simplicity and convenience provides an efficient work environment for the operator.
The wrapping wand uses quick change circular, elliptical or trapezoidal wand paths, depending on product size range. This results in increased film control. More benefits include a large size range, the ability to accept randomly spaced products and few parts to maintain.
The Douglas Contour™ heat tunnel is designed with the aesthetics of your product in mind. Whether your application calls for single or multiple lane production, unprecedented heat and airflow management ensures minimal graphic distortion, consistent bull’s-eyes and a tighter, more durable wrap. Enhanced tunnel operations significantly reduce noise and exterior heat temperatures, contributing to a quieter, cooler plant environment.
High Efficiency Heat Source
The heat system is designed so that the air supplied to the distribution system is perfectly uniform, eliminating film distortion due to hot or cold pockets. The Contour™ heat tunnel continuously recycles the air as it cools, decreasing the amount of energy required to reach operating temperature. A well-insulated heat tunnel minimizes heat loss, which also maintains a safe outer surface temperature.
Balanced Laminar Airflow
At the heart of this innovation is a combination of design features, which result in “laminar” airflow, rather than “turbulent” airflow, which most shrink systems use today. Unlike turbulent airflow, which causes a multitude of shrinking inconsistencies, our proprietary laminar design precisely balances the heated air, perfectly “coating” the film from every direction, shrinking and sealing the film in an even, predictable manner.
Precision Lap Seam Welding
Evenly heated air passing through the open web conveyor contacts the film under the product resulting in consistent “air weld” of the film lap seam. Tunnel chain temperature and airflow are precisely adjusted through product specific recipe-driven changeovers, optimizing performance. Poor lap sealing due to insufficient heat or holes melted in the seams due to overheating are eliminated, resulting in strong and even seams that hold up to the rigors of distribution and stocking operations.
Reduce energy costs and improve production efficiency with a shorter heat-up time by using gas instead of electricity to heat the shrink wrap tunnel. Tunnel heat from 75°F to 360°F in just 20 minutes. Depending on local energy costs and the type of machine used with the gas tunnel, it is estimated that companies could cut energy costs up to 75%.
