The bars are inserted into the laterally open recesses of the bar support members while the bar support members are in the initial state in order to provide a wire shell. The bar support members are bent from the initial state to the final state such that the laterally open recesses exert a clamping force upon the bars.

Abstract: An extruded scrim (12) having a diamond-mesh pattern is used to construct a personal cleansing implement. The diamond-mesh material is produced from a hydrophobic flexible polymer. The implement (10) comprises a piece of tubular scrim having a longitudinal axis. The tubular scrim is stretched transversely to the longitudinal axis and is gathered parallel to tile longitudinal axis to form circumferential pleats. In one embodiment the stretched and gathered tubular scrim is heat set in its expanded and pleated condition. A second piece of tubular scrim is placed inside the pleated and expanded scrim tubing. One end of the second piece is inverted over the outside of the pleats and connected to the other end to envelop the pleated and expanded scrim buting. In another embodiment the pleats are not heat set and remain resilient. This embodiment has a means for confining the circumferential pleats from axial expansion. A band of material is looped through the scrim tubing and around its outer surface. Pleats are then evenly distributed around the loop to form a toroidal shaped implement. The personal cleansing implement of the present invention has a high open area, without a dense center core to inhibit rinsing and drying.
