Several pieces of equipment make up the Web Delivery System to provide a smooth transition for the membrane between the Nested Product Accumulator and the winder and improve length control by minimizing shock or slack in the membrane during operation.
The S-Wrap Pull Roll unit extracts the finished membrane from the Nested Product Accumulator utilizing two rolls driven together in a serpentine timing belt arrangement.
The Shock Roll is designed to prevent shock waves originating from the starting and stopping of the winding cycle. Such shock waves can lead to deviations in wound roll length and roll finish.
The servo-driven carriage of the Shock Roll responds to the wind cycle by responsively moving up and down to ensure a steady and consistent flow of material to the winder and maintain consistent tension in the material being wound.
The Dancer utilizes a shock absorbing dancer roll to absorb momentary shock at the start of the wind cycle and maintain tension at the end of the wind cycle.
The Membrane Guide is an electrically adjusted web guide system that properly aligns the membrane prior to entering the winder.
