CNC Roll Up Cover

VINYL

Overview: The standard material we quote for
industrial roll up guards. Used in the vast majority
of applications as it is very strong and reinforced
with a polyester scrim. The most economical
and ideal material unless you have high heat or
a high abrasion environment.

Material: 18oz Vinyl
Color: Yellow, Black, Blue, Red and Green
Chemical Resistance: Yes
Heat Range: Up to 150°F
Price: $

NEOPRENE

Overview: A step up from Vinyl is the neoprene
line of shades. This material provides excellent tear
strength and superior resistance to abrasion. It
also has a higher heat rating at 212° F

Material: 16 oz Neoprene Coated Nylon Fabric
Color: Black
Chemical Resistance: Yes
Heat Range: Up to 212°F

High Temp Shades

Standard material is 18oz vinyl. However, for any environment hotter than 140 degrees Fahrenheit we use materials that can withstand the higher temperatures. Ratings of up to 1200°F.

Shade Wiper

With the use of the shade sweep wiper you can keep the cnc swarf out of the roller. The sweep is in constant contact with the shade and keeps the internal roller assembly clean.

Shade Placement

If you require a very long extension then we might have to use a roller that is wider than the shade to accommodate the internal spring. If this is necessary then we can offset the shade anywhere on the roller as shown here.

Steel Case

The steel case surrounds the roller and protects if from debris and accidental contact with other objects that might damage it. This can also feature a brush wiper. Please note that this triples the cost of the unit.

Shade Mounts

The most common end of shade mount is a pocket with a flat steel bar that you bolt to your machine. Other styles are shown above. These are only available on the heavy and super duty models.

Shade Sizes

How narrow can the shade be?

We can make the shade as narrow as you like. However, the roller drum has to have enough spring to accommodate the extension of the shade. With that, we can keep your shade width as narrow as you request and simply center it on the roller or jog it all the way to the left or right. See graphic below.. It is also worth noting that if you want a long travel and a narrow shade will will likely have to use a 3" roller tube. The more travel the machine roll up guard has the longer the spring assembly needs to be to accommodate that travel. Our estimating department will work with you on your limitations to give you some options.

As a general reference we can provide a

• 6" wide roller that extends 12" to 63"
• 8" wide roller that extends 64" to 86"
• 10" wide roller that extends 12" to 118"

Can these be used in Vertical applications?

Yes the shade can be used in both the vertical and horizontal position.

Is there a maximum overall length x width for the shades?

About 120" x 120" is the max shade size. Keep in mind if it is not used with "A" or "B" orientation below it will sag at these larger sizes.

Is there a maximum overall length / extension for the shades?

• About 72" for standard duty rollers
• About 240" for heavy duty rollers

How much will a shade SAG?

The amount of sag varies and we do not have a way to calculate that due to the complexities of shade weights, spring tension settings, and debris that maybe on the shades. If you are concerned with sag please ask your sales person to discuss it.

Any option for shades that require long shades that might sag?

• When a roller safety guard that has a very long shade and it is used in position "A" or "B" as shown in the diagram below then we have to contend with sag from gravity. If it is used in the vertical position as shown in diagram "C" then this is not a problem.
• If it is "A" or "B" orientation then we can add stiffening flats to the shade as shown in picture below "D" to give the shade structure. Keep in mind if it is orientation "A" and it is a long shade greater than about 80" then it will still sag unless the shade slides on a customer supplied frame.

Mounting Brackets

The mounting brackets are at a 90 degree, Do you have an option for a straight bracket?

Unfortunately we only have the L-shaped mounting brackets. They are removable so you could take them off and cut off one of bottom of the leg to make it straight. Keep in mind you can also toe the bracket inward / under the roller so that it reduces the footprint size.

Roller Sizes

What is the diameter of the roller when rolled up?

If you have space constraints please ask your sales person to compute the diameter of the roller when the material is rolled up. As an average the standard 18oz shade adds about .375" to .50" to the OD when rolled up. (1" roller shown below with 18oz vinyl shade)

Repairs

Can the internal springs be replaced?

Yes the internal springs can be replaced should they break from extensive use. To replace a spring we would simply need to know your order number and some application details to ascertain why it has failed. It is rare that springs fail so we would want to make sure you are using the right roller for the application. We do not repair other companies rollers.

"The roll up guarding has lasted longer than we had ever envisioned. The mechanism was rated for half a million cycles but we are well beyond that amount and the roller is still performing at an exceptional!"

Frank - CNH

"Akon worked with us to come up with a solution for an application where traditional bellows would not work. Their estimating team was extremely knowledgeable and gave us insight into how to solve our problem using the industrial retractable safety rollers. They work great"

Anthony - Borg Warner

"The roll up machine guarding is performing great. The shade material is very strong and we were extremely pleased with the pricing and quick speed that Akon worked at to get this product to us."
