Slider for sealing strip of packaging bag, has actuating units actuating closing profiles of sealing strip and displaced between rest and temporary working positions, where profiles are parallel to one another and in grip at rest position

摘要

The slider (50) has actuating units (60) for actuating complementary closing profiles (21, 24) of a sealing strip of a packaging bag (10), and displaced between a rest position and a temporary working position that is geometrically different from the rest position. The profiles are parallel to one another and grip in the rest position, and are not in grip at the working position. A control unit (70) is provided for controlling the actuating units, where the units are parallely adjacent to a displacement direction of the slider. The control unit has two tabs (72, 74) in projection on its top.
