ABSTRACT:
A two-slotted slider for ribbons comprises a bridge section between the slots, formed by two aligned arms, there being on the arms a fastening area for the ribbon generally provided with tapered reliefs for ultrasonic welding. Preferably the slider is assembled with the ribbon by first pushing both an intermediate loop portion of the ribbon and an end of the latter to pass beyond the elastically flexible arms, and then welding the said ribbon end onto the fastening area of the arms, which is facing the ribbon loop.
Welding is carried out between a sonotrode and a contrast device. The apparatus comprises the retractable contrast device and a housing for receiving the sliders one by one and displacing them between a position under a pusher for pushing the ribbon and a position under the sonotrode, as well as a device for straightening the ribbon.
