Sewing With An Electrically Heated Inner Presser Foot !?

[Colt W Knight]

Could it be a device that triggers the machine to stop instantly preventing the needle from sewing a person's hand? Like sawstop technology? It works off the conductivity of the human body.

If you look at their belts, it looks like they are making impressions at the stitch holes. It gives an interesting look.

The heating element has two wires (I believe). There might be a coaxial system to deliver electricity to the heating element like the filiteuse manuelle.

Like BigMatt said, this is strictly for decorative stitching, invented for a different look but no real function

Kind of like the old harness feet with overstitch points, but coarser and with heat.

Here is a close up where you can see the heater cartridge inserted into the side of the foot and the dark indentions around the stitch hole.

This one from the same user as the first vid Uwe posted has no needle and makes brogue punch patterns......

This one is absolutely full of "what exactly did they do there?" moments.....The bad quality video makes it even more weird.....Then things they did to those big adlers...wow..

Watch out for the scorpion claw finger biter at 2 minutes.......

This is actually a perforation machine, not a sewing machine (notice the brass punch pad on the base)

Their contribution is a heated punch head for decorative marking. We stock this model in the US... Model RP

Not a mod I'm likely to be considering!

That is what i was getting at, I guess i didn't use enough words. I use a 110 year old white rotary with an awl in it and no bobbin case to punch hand stitching holes.....Way easier that pricking irons. I can treadle it through 12 oz of veg if i give it a little help to start.....plus i dont need to spend 100 bux to switch spi....That rp machine is obviously based on the same idea.

The part that jumped out at me.was it used the same type of heater element, showing how much of an impression it can make in such a brief contact.

Is part of the advantage of these that they work better to compress the stitch line in chrome due to the heat?

Totally - veg tan is normally the only leather that responds well to cold pressure. Heated tools can "iron" in the impression better, and also leave better contrast with the burn.
