Word for the "break" where two sides of a wrapping meet

Question

Take a piece of paper or a blanket or something lying flat, with an object lying on top of it. Now the paper/blanket is folded up to wrap the object. What were the opposite sides of the wrapper now meet in the middle on top of the object, or they may overlap but there will still be an end-point of the wrapping.

What is a word for where they meet? i.e. where you could put your hand under/inside (assuming it wasn't taped together) to unwrap it again.

The closest I can think of is seam but that doesn't strike me as correct.

Sample sentence: "Holding back his excitement, Aloysius carefully inserted his hand under the XXXX of the wrapping paper and slowly unwrapped his gift"

Answer 1

A join is the place where two edges or parts come together.

Join is subtly different from joint in that a joint tends to be more complex, more carefully constructed and more permanent. For instance two pieces of paper have a join when they are stuck together but two pieces of wood are fastened together with a joint when they are shaped into complementary (usually male and female) parts, glued and then fitted together see this list of simple joints

Out of interest two pieces of wallpaper have a join where they meet even though each is stuck individually to the wall and not, usually, overlapped. Hairpieces and wigs are also said to have a join with the natural hair. This lead to the British classic comedians Morecambe and Wise using the catchphrase "You can't see the join" to get a laugh out of the idea that Ernie Wise had a hairpiece.

2. A part that has been folded over or against another: the loose folds of the drapery; clothes stacked in neat folds. –TFD

"Holding back his excitement, Aloysius carefully inserted his hand [under; between; beneath] the folds of the wrapping paper and slowly unwrapped his gift."

Answer 3

I work in a long-seam pipe mill where we roll sheet steel into tubes and weld it down its length. We use a variety of terms to refer to the skelp edges depending on context.

Most frequently, we say seam, even when the edges are not welded, such as the phrase "it has open-seam", and many of our machines have parts called "seam-turners", despite them actually turning the pipe whole.

We only say "join" when referring to the steel in the last couple of forming rolls immediately prior to welding, a space of 2 ft.

We sometimes refer to the edges themselves as a "slit", but only if they were actually cut as part of the coiling process prior to transport. (A single sheet is cut into 3 "slits" and rolled into big coils, the 2 inside cuts are sometimes referred to by the same term.)

A misalignment can cause the steel to "overlap". We consider it a defect in our product, but I think that's the best word to describe what you're talking about. In most usage you can abbreviate that down to just a "lap", but never say that word to describe steel unless you are talking about a very specific manufacturing defect.

On some machine parts, like various ring-clamps, taper-locks, and snap-rings, there is a gap called a split. This may also work under certain contexts.
