AR Metalizing paper improves quality, reduces maintenance costs

with Goldenrod pneumatic mechanical drive chucks

AR Metalizing of Franklin, Mass. (A Scholle Company) has improved its roll quality and reduced maintenance costs with the use of Goldenrod pneumatic mechanical chucks.

The company recently purchased and began using a pair of Goldenrod 1420-LF Chucks on some of the largest, heaviest paper rolls the company treats – 12\” diameter cores, supporting 8\’ wide/6\’ diameter/7-ton rolls of paper. Almost immediately, the company saw an improvement in roll quality and after 3 months of constant use, has seen little to no wear on the Goldenrod chucks.

Coating and Metallizing

AR Metalizing\’s plant in Franklin specializes in coating, metallizing, and slitting large rolls of paper that are then shipped off to converters for use in printing food and beverage labels, as well as decorative wrapping paper and other specialty products. The company is known for producing rolls of the highest quality. \”We expect quality, and so do our customers,\’ said Steve Lynch, Mechanical Design Engineer at AR Metalizing.

Lynch is a 19-year employee of AR Metalizing, and has worked with the Maintenance Group and Machine Operators over the years on numerous performance and safety upgrades of the machines running at the Franklin, MA facility. While he has worked with Goldenrod\’s shafts in the past – in fact, AR Metalizing has numerous Goldenrod 3\”, 6\”, and 12\” lightweight, multiple bladder pneumatic shafts in operation in Franklin – he only recently was involved in the purchase of the company\’s first pair of Goldenrod 12\”chucks. The Goldenrod chucks were recommended to Vacumet by their OEM machine vendor, Black Clawson -Davis Standard, who uses Goldenrod 6\” pneumatic fiber core mechanical chucks on their unwinds.

\”AR Metalizing is a company that is very much a \’let\’s improve\’ environment,\” said Lynch. \”We are always focused on improving quality and reducing maintenance issues. When our traditional chucks weren\’t performing as well as we\’d hoped, we decided to change.\”

Traditional Chuck Issues

The traditional steel chucks being used at AR Metalizing have \’keys\’ that lock the chucks onto the steel core. This design can cause grinding between the chuck and the core, leading to the need for shutdown and maintenance. \”In our experience, the traditional chucks need to be sent out for maintenance every 4-5 months, which requires labor and downtime. While we have avoided downtime by planning around the regular maintenance, this is still an issue and a significant cost,\” said Lynch.

How significant? AR Metalizing calculated the costs as follows:

Cost of maintenance in the potential machine locations where the Goldenrod chucks can be used:

– 24 chuck repairs/year @ $750 = $18,000/year

– 300 keys/year @ $60 = $18,000

– 800 key bolts/year = $300

– 20 core repairs/year @ $300 = $6,000

Conservative total: $42,300


Not including downtime costs

$42K/year in chuck maintenance is only the beginning, said Lynch. \”The wear on the chucks affects roll quality,\” he said. Traditional chucks can \’bounce\’ once they start to wear, causing \’cinching\’ (roll slipping between layers) and \’telescoping\’ (outer layers of roll sliding in or out while winding), problems that can lead to poor quality, unacceptable rolls. The bouncing also causes problems with the in-line web splicing at full speed. This is where really serious cost and quality issues can occur.\”

Goldenrod Chuck Benefits

In the over three months since AR Metalizing installed its first set of Goldenrod pneumatic mechanical chucks, the company has already seen significant quality and maintenance improvements.

\”In a word, the Goldenrod chucks have been awesome,\” said Lynch. \”They arrived machined perfectly from Goldenrod; they \’hit their numbers\’, the specified dimensions were right-on. They are clearly quality products and they have provided us with the highest performance.\”

So far, AR Metalizing has seen zero maintenance issues with the Goldenrod chucks, and the company has also seen their roll quality improve. \”When you\’re coating and metallizing 7-ton rolls, the machines need to be within tolerance,\” said Lynch. \”Precision rewind of these rolls is a huge advantage with the Goldenrod chucks – they have already paid for themselves.\”

More to Come

Because of the improved performance provided by the Goldenrod chucks, AR Metalizing already has another set on order. The company plans to further incorporate these chucks into the slitting portion of its operations. Because of Goldenrod\’s highly competent technical service, AR Metalizing has complete confidence in the company\’s products, according to Lynch.

\”Phil Pretto of Goldenrod was instrumental in helping us get the most out of these chucks\”, he said. \”He, and the internal support people at Goldenrod, have done a great job of following up and are genuinely concerned that their products are operating properly. We greatly appreciate their support.\”
