ABSTRACT:
Apparatus for applying a weldable web or band of synthetic plastic material to a package on a table has a feeding device which advances the web from a source into the channel of a mobile loop forming device loosely surrounding the package. The feeding device is arrested when the web is looped around the package so that the end portions of the resulting loop overlap. The loop forming device is then removed and the web is moved rearwardly so that the loop snugly surrounds the package. In the next step, the web is severed between the outer overlapping portion of the loop and the source, and the severing device is withdrawn so that the sonotrode of an ultrasonic welding unit can bond the outer portion of the loop to the adjacent inner portion all the way to the cut where the outer portion was severed from the source.
