Abstract

Abstract The present invention relates to an inexpensive carpetlike material and the preferred embodiments described in the disclosure are in the form of a corrugated paperboard base member to which a flock coating of fibrous material is adhesively secured to form a pilelike coating. The flock coating is applied by an electrostatic flocking process. The various types of base members described include: single-faced corrugated paperboard, double-faced corrugated paperboard having an embossed upper liner member and corrugated paperboard wherein the flutes of the corrugated medium are angularly inclined relative to the liner to provide increased resilience. The flock coating may be applied directly to the exposed corrugated surfaces or it may be applied directly to the exposed corrugated surfaces or it may be applied to an upper linear which may be in the form of a porous net.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 44 words
A floor covering material comprising: a lower liner, a corrugated medium secured to said lower liner, an upper liner secured to said medium, a flock coating of fibrous material adhesively secured to at least a substantial portion of the surface of said upper liner.
Claim 2
Dependent Claim 35 words
A floor covering material as claimed in claim 2 wherein said flock coating is in the form of synthetic fibers measuring in the range 1 to 60 denier and 0.010 to 0.200 inch in length.
Claim 3
Dependent Claim 42 words
A floor covering material as claimed in claim 2 including a second corrugated medium secured to the lower surface of said lower liner and a third liner secured to said second corrugated medium to form a double flute base for said coating.
Claim 4
Dependent Claim 17 words
A floor covering material as claimed in claim 2 wherein said upper liner is a polyolefin net.
Claim 5
Dependent Claim 24 words
A floor covering material as claimed in claim 2 wherein said upper liner is in the form of a woven net of textile material.
Claim 6
Dependent Claim 17 words
A floor covering material as claimed in claim 2 wherein said upper liner comprises a polyethylene net.
Claim 7
Dependent Claim 62 words
A floor covering material as claimed in claim 2 wherein said upper liner is embossed to form a pattern of protuberances on the surface of the upper liner to which the flock coating is applied, thereby causing said flock coating to adopt the form of the pattern of the embossed upper liner to form floor covering material having a predetermined surface pattern.
Claim 8
Dependent Claim 38 words
A floor covering material as claimed in claim 8 wherein the corrugations of said corrugated medium are uniformly angularly crushed to be permanently disposed at an incline to said liner to form a resilient base for said material.
Claim 9
Dependent Claim 27 words
A floor covering material as claimed in claim 2 wherein said upper liner is porous to permit liquid to pass into the flute formed in the medium.
Claim 10
Dependent Claim 35 words
A floor covering material as claimed in claim 10 wherein said flock coating is in the form of synthetic fibers measuring in the range 1 to 60 denier and 0.010 to 0.200 inches in length.
