Abstract
An improved corner guard assembly is provided for use in attaching suspension cords to the edgefold surface of a bonded nonwoven polyolefin film-fibril banner. The corner guard assembly comprises a pair of isosceles triangular plates, namely a front plate and a back plate. The two plates clamp a corner of the banner and are secured to each other by projections on the back plate which engage corresponding receptacles in the front plate. The projections have a generally tubular configuration in order to receive a detachably mounted locking peg for prohibiting relative movement of the projections in the receptacles. The improvement comprises mounting the locking pegs on the front plate so that they extend partly into the cavity defined by the receptacles. During use, the pegs can be driven into the projections without danger of bending or breaking.
