how about preventing hard diagonal wrinkle after lamination?

What the actual FCK is right.... Nothing is worse audio wise than hearing two vocal tracks speaking at the same time.... Besides this weird ass video, the info is good. Why TF do you need to make the video like this...?

Great info!!

Hello sir I very like your videos. I need to have a skyp with you to speak about some issue in my production line. Is there any opportunity ?

Hi, will there be formulas and easy to understand graphical illustrations in the book? Also do any of your book cover splicing and the printing industry (I'm working with machines like the CI printing drum, flexographic printing)

Now I know the purpose of that nip roller on our Northfield splicer: to remove air! Thanks.

Dave great content concerning blades. We process spun bound nonwoven nylon and for the trim we use one sided beveled blades and for multiple cuts we use doubled beveled blades, My question is as you make multiple cuts in a roll there can be what I call blade deflection because only one end of a cut roll is driven on our machines.

Dr Roidum when the machine supplier behave like a salesman, when he doesn't see the obvious problems of the paper (bagginess-patches- serious caliper variation-serious tension problems), when advised you to increase the machine speed with all the above problems, when you have corduroy edges on pope roll because of the vibrating arm (ready to crack) and tell you increase the machine speed and many more ,what are you doing?

Thank you very much, this is what I really need for my project

Hey Is there any site where i can download this book in pdf format ??

Working at a small start up converting company in Oshkosh WI. Just wanted to say thank you for sharing all of your knowledge and experience! I'm constantly learning new things from you!

Dr. Roisum. Do you have a video pertaining to paper machine refining, additives corelating to size for the paper web to be run on the machine before the winder. where the fibers formation is so tight that it causes bouncing at the winder on those certain paper grades?

Dr. Roisum. Do you have a video with illustrations on paper defects? Along the lines of alum spots, entrained air bubbles, poly, lignen spots, uncooked wood chips or pulp mill problems that show up in the sheet, picking problems, build up on head boxes that fall onto the sheet, water droplets, oil spots, etc...

Thank you Dr.i am abderrahmane process eng tissue winding spécialist from algeria

This was needed. Thanks

We do this in our facility it works great!

I find it very interesting, but I would like to see some hands on demonstrations along with the theory.

Thanks! I know what it's like to make these. I appreciate your help in understanding.

Dr. Roisum, You deepening my understanding of Roll Stresses; Now I can saving my time to learning about these by papers, hehe Thank you!

I can appreciate your concern about the accuracy of web speed/length measurement wheels. What's your opinion of some of these newer, non-contact, laser-doppler measurement sensors?

how to eliminate wrinkles at the beginning of winding? They are daughter coils that are cut over 1200mm wide and always have wrinkles at the beginning of the winding

Great vid, David. I have purchased and read cover to cover your excellent handbook. We are in the middle of designing a new web machine for C-folding an uncoated HDPE scrim around a mandrel and then joining with LDPE injected with an auger and die. Web tension is critical in the folding zone. Thanks again for your efforts.

Hello Mr Roisum. Do you also have created presentations on slacky edges ?

Can you make a video about web handling and 6 sigma .

Which Is not fundamental in web handling: torque or temperature? Thank You very much

Which Is oldest and largest industry?

Excellent laminating example with details on the types of drives.

Sir how to avoid winding defects in slitting m/c (e.g pe saperetor)

Thanks sir!

Thank you for sharing your experience with us, Dr.Roisum.

Great to hear of your candid reflections on a long career of failure (& successes!). I particularly like your "3-Step Plan" points, 26 minutes in, as these offer good advice to those determined to continue to pursue failure! Looking forward to your next installment! All the Best!

좋은 동기부여를 해주는 유머러스하고 가치있는 영상입니다. 감사합니다!

Happy New Year and Merry Xmas!

Gage variation = caliper variation?

David - Im a new grad in the pulp and paper industry (converting) and am looking for a book that will help me with identifying web/roll defects and help explain their causes and cover engineering principles. Should i get the ultimate guide to web and roll defects or the web handling handbook?

I have many years of experience which I can relate to in this episode. Many long days weekends and nights looking for an elusive solution. Thank you for your great videos

Thank You , Dr. Roisum !

Thank David for all Secrets! Very useful indeed

Thanks for your videos. I wake up early or stay up late just to see them when they come out every week. Thanks for helping out the next generation I hope I can do the same one day!

Are these instructions for Deacro and Titan Slitter Machines?

Great video, communication and common language for defects is important.

wow this is awesome! thanks for sharing.

How to join web101 course?

That book is legit. Very helpful

The art of shaping on the run the intake with duct tape and cardboard to achieve optimal trim guidance and air velocity drag on trim all because we are limited to at best 1bar differential. Or add some compressed air nozzles and take most of the fun away.

I hate feeling for tension wish they would just update the machine

In a roofing shingle manufacturing plant is it better to control web tension before the cut to length roll by drum speed or a dancer drum.

Hello I have been trying to hammer this into people's heads for 16 years. Thank you!

Interesting problem. I don't have the answer either! Some observations and measurements may help us understand. Is the core a perfect cylinder, or does it have diameter variations across the width? These would have a big effect at first but gradually get hidden (like the thickness steps from the end of the web and any tape applied) as winding proceeds. Do the chucks or winding shaft distort the core when they grip it, giving a similar effect? Both core and web may be changing moisture content more quickly at the roll ends than in the centre, either shrinking or expanding. Bagginess from this cause may decay with time after unwidnign as the water content evens out. Is the web badly wrinkled for the first few turns, appearing as a broad area of increased diameter? Measuremnet of pressure on the core across the width show huge variations from stacking persisent thickness variations (analogous to the diameter variations at the roll surface). The pressure may partially fall with time if the material is viscoelastic. When the web is unwound, I would expect the MD recovery to vary with the pressure experienced. I hope these suggestions help.

Dr Roisum, you must make a video about the managers desire of increasing the machine speed (when you have lots of web break, lots of machine malfunctions, very old machines, the machine crew and the technicians doesn't support with knowledge , bad quality final product) .
