Abstract
In a skidproof device continuously molded of synthetic resin and adapted to be used with a disposable companion sheet product, a multiplicity of skidproof engaging elements are molded on the front surface of a substrate sheet for mating with engaging elements of the companion sheet product. Each skidproof engaging element is composed of a single stem, at least two necks branched and gently sloping upwardly from an upper end of the stem, and at least two heads extending one from an upper end of each neck with an upward gentle slope. Each head has on its top an upwardly convex arcuate surface. Having the differently directed engaging elements, the front surface of this device is smooth in touch and non-directive to give adequate resistance to skidding.
