How is carpet edged to hard flooring?

[two2go]

Our coach has a strip of vinyl flooring running back from the door to the bathroom and covering half the width of the coach. The other half of the flooring plus the slide is carpet. Where the carpet meets the vinyl, it seems to be rolled under itself and does not have a transition strip. The carpet edge is very neat and straight and is not thick, probably due to thin cheap carpet.

How is this roll edge made and how is it fastened to the subfloor? I want to replace the vinyl and a lot of the carpet and create a new edge further forward between the existing carpet and new flooring. Any suggestions on the best way to do a transition that looks professional without special techniques or tools? I am thinking of using a floating interlock floor that looks like grouted tile. We don't want wood.

You are correct in the fact that the carpet is just rolled under itself. It is then stapled to the sub floor with pneumatic stapler along the rolled edge. It is not hard to do but you will have to have a stapler that will handle 1/4 to 5/16" crown and at least 1" length.

There is a U shaped strip available that fastens down at the edge of the carpet.You trin the carpet and tuck it under into the U.After the carpet is tucked in you tap on the edge ,closing the U and binding the carpet.In a stick house the padding compensates for the thickness of the doubled under carpet.

There are several types of transition moldings available for floating floors. They are available from the flooring manufacturer.
We used T molding, carpet transition molding, stair edge molding and multi-purpose molding when we pulled the carpet out and installed laminate flooring.

Thanks for the input. I looked for the options suggested at the store. One of these should do the trick. I was mainly wondering about the factory transition that used no apparent hardware.
