My sealing procedure may not be according to Hoyle..... but I don't play cards
I pulled rows then sealed the extending weft fibers.
That dried overnight, so it's good and dry.
I don't like seaming with "almost dry" sealer because it behaves like contact cement when bumping the seam edges into position. I used Orcon, your mileage may vary.
I trimmed off the weft strands and then did a slow and meticulous job of edge sealing.
I sealed as minimally as needed, but after applying a bead to the edge, I used my thumbnail to carefully rock or "smoosh" a thin film of sealer onto the warp chain just underneath the face yarn... It feels like a surgical procedure the way I do it, but...
I gotta be me............. I gotta be me....
Whether I'm right or whether I'm wrong
Whether I find a place in this world or never belong
I gotta be me, I've gotta be me
What else can I be but what I am....
Everybody together now.....
Ok, ok, where was I when Sammy butted in?
Oh yeah, that edge sealing dries pretty fast because of the initial sealer that I slobbered all over the weft cables the day before.
Lastly, I do one more thing.
Thermo
Taboo?
Unheard of?
I don't care, it works for me.
I apply an extremely thin film. It is just enough to make the carpet edges a tiny bit shiny, virtually zero thickness. It stops the edges from prematurely sticking together upon contact when positioning and putting the seam together. That thin film has one more benefit. I have never used anything but a star roller
It applies pressure and applies pressure differently, with more control than a flat roller.
Anyhow, that tiny film of hot glue on the seam edge can also help to grab onto a couple of filaments at the bottom of a loop. Squeeze out can do the same.
If controlled carefully, this tiny amount of thermo contacting a couple of filaments at the base of a loop can tilt a pile loop and make it lean inward towards the seam edge. That can really help some times.
It's an art form. I'm not talking about squeezing a glob of hot glue up into the pile, creating a hard lump. A star roller is your best friend if you think this will help improve a seam.
Worried about the star roller leaving dents?
.....well, then don't use your Roberts seamer set on high, and use a star roller, then drop a seam weight on the roller impressions to cool that way.
Use the star roller, brush the roller marks out with your hand, and THEN apply a weight and you will have zero issues.
Anyway,
Seal the weft.
Trim the weft.
Seal the seam edge
Lastly, super thin film of thermo edge sealer.
......then slap the seam together.
Lastly, the KoolGlide and SeamerDown will perform miracles on patterned looped pile carpets.
Ok, Ok, thats enough for now.
