Mode of Operation

The product is automatically or manually loaded onto the infeed conveyor of the wrapper. The conveyor belt moves the product into the tube of film formed by the film former. A guide located at the back side of the infeed conveyor guides the product as it travels through the film former. The machine detects the product and starts the powered film unwind feeding film. This eliminates any film tension against the product.

The product in the film tube then continues into the L-seal area. When the product clears the seal bars the discharge conveyor stops and the seal bars close, sealing and cutting the film around the product. If another product enters the infeed conveyor and the seal bars are closed the infeed conveyor will stop just before the product contacts the seal bar. After the seal dwell timer times out the seal bars open, the infeed conveyor restarts if it had stopped and the discharge conveyor restarts transferring the product sealed in film onto the customers conveyor or an optional tunnel conveyor belt. The scrap film created by the side seal is taken up by a film rewind system located under the discharge conveyor.

Competitive Advantages

User-friendly color touch-screen operator interface.

Innovative pinch roller design gently pulls raw film ahead of seal bar. Film breaks are eliminated on even the lightest film gauges. Precise control of the film web reduces film width requirement for most products.

A single adjustment provides a centered seal for best product appearance, while limiting seal head stroke for the fastest production speeds. A proprietary Seal Height Calibration Sequence measures seal head height and automatically determines proper seal head cushioning for all seal heights.

A guillotine style seal head provides consistent seal strength for all product profiles. Vertical movement using linear shafts, bearings and reciprocating chains, is proven to be a superior sealing method eliminating the scissor action and linkages associated with pivot style systems.
