Where can I buy a latex sheet seaming machine in uk?

Question:

Answers:
You can apparently "customise" a regular sewing machine:

"The sewing machine is an ordinary industrial type with a Teflon ring foot. The machines have to be set up specially so that a perfect stitch is formed. The heavy duty thread passes through a bath of silicone this lubricates the thread so that it will pull tight to form a stitch and cools the needle as it can get hot passing through layers of rubber."

Otherwise, seaming the sheets with a latex adhesive rather than stitching seems to be quite promising, too.
