binder question

[keithski122]

I'm just in the process of sorting out a binder attachment  and was wondering what the bent wire is for. I know the binding feeds through it but is it for extra tension or just to guide it into the binder better? On my set up it will need rebending as the flatbed of my machine is in the way, however this means the tape will be higher than the binder shell.

The bent wires are a guide to maintain alignment and a smooth entry into the folder body. The way the spool is mounted determines the back pressure. You want the least drag on the spool as possible. I once had a custom platter for edge binding spools that road on ball bearings and extended horizontally over the back of the table.

Thank you. Its for carpet binding with the binding being strips of leather or vinyl, maximum  I guess of three metres long so no spool.I'll leave the wire off and see how it goes, at the moment its more important to get everything else lined up right.

Just for information binder has throat of 9mm material thickness, with binding material size of 26mm (1 inch) 1.8mm thickness.

If you don't mind, please post a link to that binder attachment.

Are you trying to attach this to a flatbed or cylinder bed machine?

On a flatbed machine.I've previously fitted a different binder but never got it working quite right due to the binder not being suitable for a thicker material.It worked but seemed to stretch the binding.Heres some pics of how it was with the older binder and binding results.

you don't have any adjustable play for height and angle in that Binder setup, on the flatbed . looks to be that the throat is screwed down to side-plate, with limited only a In-Out play for how close you want to the foot/needle . also maybe put a picture up with a more top view of your attachment .
what exactly is your machine ?

I just got that same tape folder to try out on my 441 class machines. I think it’s designed for application where the tape folder floats in mid-air, mounted to a swiveling arm. 

That tape folder is BIG and I think it’s designed for 441 class machines (also implied by the KHF-441 part number.) It has an offset on the underside to lower it for proper alignment with the throat plate. I don’t think this tape folder is suitable for mounting to the slide plate of a flatbed machine. 

Here are some pictures of mine (wire guide not installed):

 

There’s more to the binding story, especially more parts. Here’s the full set of parts I got to make this tape folder work on a 441 class machine. I’ll make a separate topic once I’ve had a chance to try it out. This photo is just to illustrate that it takes more than just a tape folder to do binding on certain machines.

At the moment all binding I do is by hand so just playing about to see if I can get a neater/quicker finish, if it doesn't work no great loss I'll continue to do it by hand.

The set up above worked in a straight line apart from stretching the binding causing the carpet to wrinkle.I don't think I tried it on a curve.I've set it on a spare plate so if I get it to work it will be a straight forwards job just to change the plate and the feet and off I go.Binder is fixed as close as posssible to the feet on max stitch length with a couple of mm clearance, once set should not need moving, height is a low down as possible.With the new attachment I've mounted it using an adapter plate so if I need to adjust it back or forth its a simple job to make a new plate.Machine is a typical tw1-899 used for all aspects of auto upholstery so can't be set up purely for binding.
