Holographics Embossing - Medium Web Principle The substrate passes between a rotating embossing roller which carries the embossing shim and a rotating compliant impression roller. The embossed area produced is up to 40 inches long and as wide as the shim. The shim itself takes up just over half the circumference of the embossing roller so each revolution produces an embossed area and a blank area similar in size. The blank area is embossed by passing the substrate once more through the embossing roller and a second compliant impression roller. A variable length timing loop is incorporated to allow precise positioning for the second embossing. The MW range uses high temperatures and pressures to emboss a wide range of substrates with holographic images. The image is derived from a micro embossed nickel plate mounted on an embossing roller. The substrate is reel fed to the embossing unit and re-reeled after embossing. The process used can be hard or soft embossing, dependant upon the substrate being embossed. The MW range is constructed on a standard design precision space frame. The basic machine uses three modules to mount the unwind, embossing and rewind units. The construction ensures straight, low stress web handling, essential for trouble free processing. The modular construction also allows easy modification of the web path and the economic addition of other functions such as laminating or slitting units at a later date. Parent reels are mounted on 75mm air shafts in quick release safety chucks. The product is rewound on an identical unit. Unwind and rewind tension control is provided by closed loop load cell systems allowing substrates down to 12 micron to be processed without stretching. Controls are mounted in a free standing console adjacent to the embossing unit and are designed to be simple and user friendly for maximum productivity. |
