Female loop portion having film and filaments anchored by heat-shrinking
09788614 · 2017-10-17 · ·

A female loop portion for a hook and loop self-adhesive, comprising a film (1) made of at least one thermoplastic and a plurality of filaments (2) which are separate from one another and attached to one of the surfaces of the film, each filament comprising a series of fastening sections (15) and a series of loop sections (4) alternating with the fastening sections, the filaments being attached to the film along the fastening sections while the loop sections are at a distance from the film so as to form loops, and characterized in that a cross-sectional area of one loop section of a filament is less than a cross-sectional area of one fastening section of said one filament.

METHOD AND DEVICE FOR THE APPLICATION OF SHRINK FILM SLEEVE

A method and a device for applying a shrink film sleeve to a container is provided. The method includes perforating the shrink film sleeve at predefined intervals, expanding the perforated shrink film sleeve by means of an expansion device, such as an expansion mandrel, conveying the expanded shrink film sleeve along the expansion device by a conveyor roller pair, tearing off the shrink film sleeve at the perforation by means of a downstream dispensing roller pair whose conveying speed is at least temporarily higher than the conveying speed of the conveyor roller pair, and shooting the torn-off shrink film sleeve onto the container.
