Wrap Belt Assembly
Wrap Belt Systems are used to spin the product (typically a bottle) to finish the application of a label. This can also be used for square and rectangular shaped products as well. The wrap belt assembly consists of an adjustable Linatex® coated timing belt and an adjustable padded back-up plate. The standard back-up plate is designed for round products

Product Specifications
The wrap belt assembly provides easy vertical and horizontal adjustment for quick product change over. Consult Factory if a larger range of adjustment is required

Bottom of Belt	Min	Max
Vertical	5/8"	1 3/8"
Horizontal	0"	7/16"

Conveyor Installations
Model WB mounts to the T-slots in LSI's table top chain conveyor with 4 bolts and T-nuts.

Encoder Option
	An optional encoder assembly provides a signal for synchronizing labeling head speed to wrap belt speed.
Drive Options
	The standard DC motor and drive controller is designed for belt speeds from 0 IPM to 1290 IPM.
	An optional AC motor with variable frequency drive controller automatically synchronizes the wrap belt speed to be two times the conveyor speed.
Belt Options
	The standard wrap belt assembly is designed to apply labels up to 15-1/2" long and is available in 3" tall and 6" tall models.Custom machined belt surfaces are available to accommodate irregular product profiles.
Back Up Options
	Optional back-up plates with thicker padding are available for wrapping labels on oval, square and rectangular products. Consult factory for details.
Wrap Belt Applications There are 2 basic methods used for wrap applications. These are synchronize dispense and pre-dispense. Synchronize Dispense - This is the most common method. The method locates the peeler bar of the labeling head next to the wrap station. Products are guided to the tangent point created by the peeler bar, wrap belt and product. The label is dispensed directly into this tangent point and the wrap belt will take away the product and spin it to finish wrapping the label around the product.
	LSI Machines that feature this method: Model 1500 - Open Frame Wrap System Model 4550 - Main Frame Wrap System Advantages 1) Higher application rates 2) Typically no change parts 3) Very versatile Disadvantages 1) May require change parts
Pre-dispense or "Flagged Label" method - incorporates a top hold down assembly between the in-feed device and the wrap station. By utilizing this method, the need to match speeds goes away. Also this method provides a means to incorporate peripheral devices such as label on product inspection and rejection.
	LSI Machines that feature this method: Model 4500 - Main Frame Wrap System Advantages 1) Easy to set up, no speed matching required 2) Keeps products on fixed centers 3) Easy to incorporate vision and label inspection systems 4) High speed capability 5) Very accurate
