Abstract
A slider to be applied to ribbons for clothing articles comprising a first portion and a second portion integral with the first portion. The first portion on a surface thereof is provided with projections for ultrasonic welding to a ribbon. The second portion has two slots that slidingly receive a ribbon, these slots being separated by two confronting, resiliently flexible arms. In the assembling process the slider is first secured to the end of a ribbon by welding, generally ultrasonic welding; then a punch moving transversely of the arms pushes a length of the ribbon beyond the arms, simultaneously flexing the arms. When the punch retracts, the arms spring back to their undeformed condition and the ribbon is left astride the arms.
