ABSTRACT:
An apparatus for tightening elastic and non-elastic bands designed for fitting to the frames of pieces of furniture includes a tensioner consisting of a roll arranged for rotation about its own axis. The roll has a pressure member mounted in spaced relationship with the roll so as to permit insertion of bands therebetween. The supplied band is folded backwardly over the top of the pressure member to be fastened to the frame of the piece of furniture. During a first rotation of the roll, the pressure member applies, by friction, a slight tractive force on the band, while permitting it to run with respect to the roll. A subsequent rotation of the roll brings the backwardly folded portion of the band to bear on that portion of the band supplied from the reel, which lies on the least one portion of the surface of the roll, whereby running of the band is then prevented by friction such that a further rotation of the roll causes tightening of the band.
