Abstract
A polymeric base sheet has a plurality of protuberances and valleys located on a first side of the base sheet. A layer of bonding material is located on a top surface of the protuberances and is substantially absent from the valleys located between the protuberances. A plurality of skid-preventative particles are secured to the layer of bonding material so as to be substantially absent from the valleys. A sheet of this construction allows the skid-preventative particles to be used in a more efficient manner than heretofore known. By placing the skid-preventative particles exclusively on the protuberances of the base sheet, less particles need to be employed to obtain the skid-preventative surface.
Claims9
A skid preventative sheet, which comprises:
- (a) a resilient polymeric base sheet having a front surface;
- (b) a plurality of a integral protuberances projecting from the front surface, there being a plurality of such protuberances across the width and down the length of the front surface of the polymeric base sheet;
- (c) a discontinuous layer of bonding material being located on the protuberances and being substantially absent from the front surface in the regions between the protuberances;
- and
- (d) a plurality of skid preventative particles partially embedded in the layer of bonding material and being substantially absent from the front surface in the regions between the protuberances.
A sheet which comprises:
- (a) a polymeric base sheet having a plurality of protuberances and valleys located on a first side of the polymeric base sheet;
- (b) a layer of bonding material being located on a top surface of the protuberances and being substantially absent from the valleys;
- and
- (c) a plurality of skid preventative particles being secured to the layer of bonding material and being substantially absent from the valleys.
