    Abstract: An example includes a method for forming tubular lengths of web material. The example can include winding a portion of web material in a tubular configuration such that opposite vertical ends of said linear portion overlap. The example can include welding said overlapping ends to fix said linear portion of web material in sleeve configuration. This welding can include heating up at a first temperature a first region of said portion over the whole of which said ends overlap and heating up at a second temperature lower than said first temperature a second region of said portion adjacent to said first region, said ends of said portion of labelling web material overlapping over only a part of said second region. One or more examples relate to a forming unit configured to implement the method outlined above.
