With the Edge Marking System, code and/or defect marks are made along the edge of the web. Marks can be long or short, continuous or pulsed, or can be coded to represent unique data that is coded downstream. The length of the mark and the delay can be controlled by timers or by actual distance with a tachometer input. The mark is generally an atomized spray, but can also be an un-atomized stream depending on the substrate. Ryeco’s Edge Markers are available in arrangements capable of marking in up to six colors. The company’s Edge Markers use a jawed design that integrates a vacuum overspray evacuation system directly onto the marking head. In addition, the sprayer is angled at 30 degrees off-web to ensure that any overspray is immediately evacuated.
Ryeco’s Lane Marking Systems are ideal for placing marks – defect or code – at any position on a moving web. Marking is typically done upstream from a slitting operation and in the case of defect marking, allows only the specific defective lane to be marked for removal rather than the entire web width. Lane Marking is often used in cases where the material being produced is of significant value such as battery foils and medical membranes. Ryeco manufactures its Lane Marking Systems in a number of arrangements with almost no limit to the amount of independent marking modules.
