| (54) | Method and tubular band with a separable portion for carrying out quick overlocking |
| (57) A method of making quick overlockings comprises the steps of manufacturing a band
with at least one tubular portion in which at least two courses of the knitted fabric
are made of a yarn capable of being melted upon increasing of its temperature beyond
a predetermined value; folding back the band for obtaining a loop along the band itself
with the two courses of meltable yarn disposed on opposite walls of the loop; inserting
an edge of the knitted fabric to be trimmed into the loop; sewing the band to the
edge in such a manner that the stitching does not affect the loop bottom included
between the two courses of meltable yarn; heating the band beyond the melting temperature
of the meltable yarn so as to separate the loop bottom from the rest of the band;
slipping off the loop bottom from the band inside. The invention also relates to a
tubular band intended to be folded for receiving the edge of the knitted fabric to
which it is to be sewn and formed with the at least two spaced apart courses made
of a meltable yarn. |
