April 26, 2017 Film Handling: Low Inertia Roll / Video

Inertia Roll is driven by quite limited force.
Why is it possible?

This roll makes use of thin-wall Nickel sleeve on its surface.
When air goes into this roll, by this air thin-wall sleeve floats, which succeeds in limiting loss of rotational resistance mechanically.

Rotational resistance is expressed by inertia moment.
This resistance goes down to one fifties of rolls of the same size.

This is explained by this video.

Roll is heavy without air

Sleeve floats by air and rotates fast

Without air the roll needs several coins for rotation.

By air the sleeve floats and rotates by only one 1 gram coin.

If this roll is used for film conveyance, what happens?
When film goes on this roll, this roll begins to rotate and send this film to the next destination and does not give any other stress on film.

April.19, 2017 Merits and Applications of Metal Belts

We produce metal belts on custom.
Metal material is stainless steel mainly, including several grades.
Why do our customers choose metal belt rather than plastic and rubber belts?

They do because
・only limited dusts are found during operation nor frayed,
・belt surface is very flat,
・they are strong against heat, corrosion, and abrasion,
・stainless steell is hygiene, and
・metal belts do not elongate easily.

So, our customers choose our belt for driving arms, intermittent conveyance, continuous process flow rather than batch system, suction conveyance for web handling, and material heating and pressuring.

If you have a chance to come to Japan, please visit DYMCO.
we are about one hour from Tokyo or Haneda and can show you our belts and conveyors.

Fim Tech Japan is now open till April 7th this week.
Dymco presents tools for web handling.
One of them is replica of a patterning mold.
Patterning on film surfaxe crates uniques function on each film.
Patterns are made by laser and sharp drills, whick requires high-spec machine, jigs, time adn cost.
If it wears out, we need to make it again, spending a lot of time money once again.
Replica sleeves solve this issue.

We make replica sleeves from the original patterning mold.
At present its size and patterns are limited, but please try contact to us.
We will try.
3 sleeves on your right are replica sleeves, made from the original mold on the left
Replica is not a plate.  It is cylindeer, this is why patterning is done continuously as below.
