How Does Roller Heat Transfer Machine Work on Sublimation Paper?

Sublimation papers are designed for use with roller heat transfer machine. The paper incorporates a thermal adhesive that sticks the fabric to the paper. This prevents the paper from lifting up or moving when the press is opened, thus avoiding an undesirable blurring or doubling of the images known as “ghosting”.

Typical settings when performing sublimation for textile are approximately 400 deg F, with a dwell time of about 40-45 seconds and most polyesters handle this high heat without problems. Some specialized materials can yellow, loose their elasticity or melt at 400 deg, so in these cases the temperature can be lowered and the dwell time increased, however it should be noted that sublimation doesn’t occur properly as temps drop below 320 deg F. During sublimation the paper must be held tightly under pressure against the fabric to ensure sharp transfers.

Looking like something you might expect to see in an industrial laundry, roller heat presses are large, made from a lot of heavy-duty metal and usually more expensive than Flatbeds. They are however generally faster than flatbed presses, require less operator attendance and are the only option if you intend to produce rolled goods.

Paper and fabric are fed together (often on a roll) into the unit and a heat resistant belt holds the fabric tightly against the rotating drum. The fabric and paper exit out the other side of the drum where they separate and are wound up on their own individual take-up spools.

How to Maintain Roller Heat Transfer Machine Correctly?

rotary heat transfer machineSublimation printing is being more and more popular. When customers consider buying machines, except care the cost, but also care how to maintain machines. Now Feiyue Digital will be together with you to discuss how to maintain roller heat transfer machine.

1. The handling of machine breakdown:
The machine could occur breakdown during working, breakdown handling can be divided into two types: non-stop working and stop working.

1) Handling of non-stop working breakdown:
A. When finding heating blanket with small stuff, you can clean it with brush. If can not, you can removed it when it stops.

B. When finding blanket with small stripes, you can use small stone to grind it . If can not, you should send it to repair. But it’s seldom to appear such problem.

C. If you find color difference between both sides and middle place, you can adjust the transferure on both sides, or adjust the space between roller drum and blanket.

D. If you find the parts are loosing during working, you should fasten the screw in time.

E. If you find heating transfer with false designs, you can slow down the machine.

F. When finding the blanket and conveyor belt deviate to one side, you can adjust manually, and our roller heat press has automatic function of deviation correction for blanket and conveyor belt..

G. When finding the fabric with staining, you should turn on drying system to dry the fabric and avoid the staining.

H. When finding the fabric or blanket tension is too strong or too small, you should adjust the speed between units or tension device in time, make sure proper tension.

I. When the moisture is uneven of fabric, you could adjust the transferure.

2) The handling of stop working breakdown:
A.If some sharp material into the roller, stop it and take it out.

B.During heat transfer, if find fabric too much thread, and wind into the roller, you should stop machine and deal with it in time.

C. When the blanket used for long time, and blanket too thin,heating not steady, you should stop machine and take out to change a new one.

2. Machine maintenance:
1) Check screws, parts, roller, axis, blanket etc frequently.

2) Before operating roller heat transfer machine, you need to make oil to the active parts

3) Clean the machine every week.

In the future, roller heat transfer machine will develop towards to total automatic. maintenance becomes more easy. At the same time, the stability of the machine will be toward high efficiency.
