Banner hem question

[Phill Fenton]

Good question Mike – I was going to start using these tapes but I too am not convinced they’re the best way to produce a hem. Also eyelets – I have tried Graffityp eyelets that are a push fit onto banner material and do not make a hole in the banner itself – any thoughts on these?

[Robert Lambie]

we hem with tape with lots of our banners, coupled by self piercing eyelets fitted using a pull down arm mechanism type thing.
if i am joining banners or if the banner is a large banner i use our leister hot-air banner material welder for the hem and joins.

We bought a strong sewing machine… and learnt it

[Mike Grant]

I found a local company today that repairs tents and they are even closer than my last supplier and they do supply sign companies with this service.
So I think I have solved my problem.

Cheers guys 😀

I wonder if a hem is actually needed, ok it looks "finished" but hems on cloth were to stop fraying of the material. On pvc, its probably fine just to eyelet?

often wondered the same peter….a customer brought in an old pvc banner no hem just eyelets and she said it was 3 years old…..not one bit of fraying seen 😀

hemming strengthens the banner and prevents tearing. particularly where the eyelets are. not all banners are fitted to a flat backing, so act a bit like a flag in the wind… this is where tearing happens most often. also, if the eyelet is positioned too near to the edge of the banner.

[Peter Normington]

Sorry Rob, once again you lost me with your technical terms..falt backing…& paqrticularly.

But Pvc dosn’t usually tear, especially with welded rather than riveted eyelets, Banners are so cheap to buy anyway, eyed and hemmed, hardly worth making your own, unless of course you are printing them. thats when it may be quicker not to bother about the hem. Trouble is, having thought about it, printed banner material is far weaker than the traditional pvc banner

OK so I’m of to bark up another tree,,, 😉

[Marcella Ross]

nope…. the technical term Rob used that got me was ‘hammens’ (?) 😉
i buy all my banners in already made up. I buy from General Banner and they’ve never let me down, not expensive either. All their banners are hemmed with tape not stitched. I’ve never had a customer complain and never had any problems with this.

[Robert Lambie]

bog off the pair of you 😉 :lol1: :lol1:
im crap at spelling at best of times but i have a wee cheapy keyboard just now with sticking buttons, and keys you have to jump on to get them to register. so thats my excuse and I’m sticking to it.. :tongue:

i think i should at least hit spell check at the end of my posts eh? 😳 :lol1:

I’ve amended the post by the way peter 😉 i know reading something i type in a hurry is like cracking the devinci code :lol1: :lol1:

you’ve lost me now mate.. how do you mean welded eyelets?

yeah banners are cheap as chips… but you can still save a fair bit making your on and speeds up production. if printing you don’t have much option but to make your own.
some cheap digital banner material, but more so the budget type run of the mill banner material is far easier to tear.

[Marcella Ross]

that would be the Da Vinci code Rob ……… 🙄 😀 😉

…. sorry couldn’t resist!

[Peter Normington]

Rob Trounce eyelets are plastic. no brass, they are heat welded into the material, so are part of the banner and not just crimped.
Do you want a pic?
Peter

[Peter Normington]

Picture anyway

Peter

[Marcella Ross]

Mmmm…… i buy all mine with brass eyelets. Are they as strong?

[Peter Normington]

Anything that is bonded, as oppossed to crimped has to be stronger, but unless your banner is being towed behind a jumbo jet, I doubt your customer will know the difference, like I assume he/she will not notice if there is a hem or not.

Peter

[Robert Lambie]

marcella… :lol1: :lol1: :lol1: maybe the pentagon should have me working for them. 😎 :lol1:

ahhh i see what you mean peter, yeah i know the sort, but never used them. to be honest peter, its not so much the method in how the eyelet is done, its just down to the force in which the ropes will pull on that centred area that will cause the ripping. that said, those eyelets look like they could help in ways. at the end of the day i have saw lots of banners blowing in the wind with large chunks ripped off, bits of rope with a full corner still attached etc…

here is some banners i fitted this afternoon. different situation again but i have used a combination off banner tape, leister banner welded… even some homemade washer type fixings with rivets to prevent tearing.

have you been going to the Robert Lambie school of spelling? Whats a jubo jet?

[Peter Normington]

Rob the banners look good, but correct me if I am wrong, I don’t see any way that they are kept under tension? with temperature changes pvc can change drastically, sagging in the heat, and under tension when cold, I find spring loaded, or a similar system helps to prolong the life of the installation (Banners should generally be considered temporary though)

Peter

[Robert Lambie]

I guess your looking at the top rail mate…. the bottom rail has another bar but is attached to springs. it was pretty windy today when i put those up… you could actually see the prings working as the wind kicked in.

yeah banners are normally temp, but only as temp as the customer wants. i know they will want these up for about 2 years and i recon they will last. the only issue should be UV stability and i recon that will be fine too.

those are printed banners using a thick block-out digital banner material, double sided but not one skin. the banner goes up one side, over the bar and down the back meeting up at bottom again. each side/edge is heat welded as is the join. i have also used banner tape where i couldnt get the welder in. i have also doubled up the skin with another layer of banner top and bottom on the inside to prevent tearing where the stress areas are. i then fitted those rivets and washers to strengthen again.

[Chris Dowd]

When we use banner tape to make pole pockets, we also eyelet both sides (brass eyelets) as we have experienced the tape separating and failing before when put under any kind of wind loading!

[Peter Normington]

Belt and braces as usuall then Rob, couldnt see the springs at the bottom.

Peter

[Robert Lambie]

yeah i had a look there peter, i can see why you couldn’t notice the springs at the bottom from those pictures. ill see if i have any shots of the bottom of the banners.

Chris, yeah that’s one of the reasons i used those rivets and washers. the double sided tape runs horizontal to form the loop/pocket then i have used heat welder to seal the edges of the banner. the rivets are there to prevent the possibility of the banner separating in either direction.

[Peter Normington]

Rob I couldnt enlarge the pics, not doubting you at all, I do know you are belt and braces though. But asking the question, may give advice to others, if you see what I mean…

Peter

[Robert Lambie]

yep, definitely peter… couldn’t agree more.

I’ve attached a picture of the same system i have used… obviously not my banner though. Personally i would have liked the spring system to be a bit more substantial, not so much the spring, just how it is fitted, hooked on. but i guess i am maybe being over picky 😕 :lol1:

i need some banner tape for some samples i am doing on my cadet can anybody point me in the direction of supplier of banner tape
cheers.
i have a sample called banner bond but no details

[Chris Dowd]

Derek,

Bannerbond is the B & P Lightbrigade product (01932 568555) and is the one that we use, would be interested in who else supplies it also though!

Chris.
