A DEVICE FOR APPLYING A PRETENSIONED STRAPPING, WRAPPING OR OTHER BINDING ELEMENT, SUCH AS A THREAD, A WIRE, A THIN STRIP, E.G. TAPE, A THIN SHEET OR FILM, OF FLEXIBLE MATERIAL AROUND AN OBJECT OR A NUMBER, E.G. A ROW OR A STACK, OF OBJECTS

摘要

A device for applying a bonding element (6,7) of flexible material around an object or a set of objects (1), said device comprising a track (2) for conveying the object(s) through the device, two reels (4,5) for the supply of binding material, means (20,21,34,35) for pulling previously interconnected pieces (6,7) of binding material forming together the binding element from said reels, means (28,29 and 20,21 34,35) for blocking the supply of further binding material and subjecting said element to tensile stress and means (10, 11) for folding or bending a portion (6,6 sec ,7,7 sec ) of the binding element around the object(s) and close the then produced loop on the one hand and to stretch the remaining portion (6 min ,7 min ) of said element across the conveying track on the other hand, so as to form part of a new binding element to be used during the next following binding cycle, the pulling means (20,21,34, 35) forming part of the blocking and tensioning means (28,29, 20,21,34,35).
