Abstract
Abstract An acoustical wall panel includes an elongated sound absorbent board faced with a needle-punched non-woven fabric provided with a woven scrim backing and having linear ribs extending longitudinally of the panel. Such panels are mounted by generally H-shaped splines concealed by the panels. The lofted texture of the fabric and the linear ribs help conceal a seam between two panels.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
143 words
An acoustical treatment for a wall comprising an elongated generally H-shaped spline mounted on the wall in parallel relationship thereto and a pair of elongated generally rectangular sound absorbent panels mounted on the wall in cooperative engagement with said spline respectively on opposite sides thereof and in abutting relationship with each other at front longitudinal edge portions thereof, the longitudinal edge portions of said panels being provided with kerfs for respectively receiving portions of said spline, each of said panels having a fabric adhered to a front face thereof and cut flush with the longitudinal edge portions thereof but nevertheless concealing the joint between the abutting front longitudinal edge portions, the fabric being formed of non-woven staple fibers needle-punched in a first needle-punching operation, the fabric having linear ribs formed in another needle-punching operation, and the ribs extending longitudinally of the mounted panels.
Claim 2
Dependent Claim
143 words
An acoustical treatment for a wall comprising an elongated generally H-shaped spline mounted on the wall in parallel relationship thereto and a pair of elongated generally rectangular sound absorbent panels mounted on the wall in cooperative engagement with said spline respectively on opposite sides thereof and in abutting relationship with each other at front longitudinal edge portions thereof, the longitudinal edge portions of said panels being provided with kerfs for respectively receiving portions of said spline, each of said panels having a fabric adhered to a front face thereof and cut flush with the longitudinal edge portions thereof but nevertheless concealing the joint between the abutting front longitudinal edge portions, the fabric being formed of non-woven staple fibers needle-punched in a first needle-punching operation, the fabric having linear ribs formed in another needle-punching operation, and the ribs extending longitudinally of the mounted panels.
Claim 3
Dependent Claim
32 words
An acoustical treatment as claimed in claim 1 wherein the ribs of said fabric are generally of at least two different sizes, one size being wider and more raised than the other.
Claim 4
Dependent Claim
16 words
An acoustical treatment as claimed in claim 2 wherein the different sized ribs are non-uniformly distributed.
Claim 5
Dependent Claim
18 words
An acoustical treatment as claimed in claim 1 wherein the fabric is provided with a woven scrim backing.
Claim 6
Dependent Claim
30 words
An acoustical treatment as claimed in claim 4 wherein the woven scrim backing is attached to the fabric in yet another needle-punching operation performed before the forming of the ribs.
Claim 7
Dependent Claim
40 words
An acoustical treatment as claimed in claim 1 wherein rear longitudinal edge portions of the panels are relieved to provide clearance for a central web portion of the spline and enable the front longitudinal edge portions to be tightly abutted.
Claim 8
Dependent Claim
83 words
An acoustical wall panel comprising an elongated generally rectangular sound absorbent fabricated fibrous board provided with a kerf along a longitudinal edge portion for receiving a portion of an elongated mounting spline and a fabric adhered to a front face of said board and cut flush with said longitudinal edge portion, the fabric being formed of non-woven staple fibers needle-punched in a first needle-punching operation, the fabric having linear ribs formed in another needle-punching operation, and the ribs extending longitudinally of the board.
Claim 9
Dependent Claim
83 words
An acoustical wall panel comprising an elongated generally rectangular sound absorbent fabricated fibrous board provided with a kerf along a longitudinal edge portion for receiving a portion of an elongated mounting spline and a fabric adhered to a front face of said board and cut flush with said longitudinal edge portion, the fabric being formed of non-woven staple fibers needle-punched in a first needle-punching operation, the fabric having linear ribs formed in another needle-punching operation, and the ribs extending longitudinally of the board.
Claim 10
Dependent Claim
31 words
A panel as claimed in claim 7 wherein the ribs of said fabric are generally of at least two different sizes, one size being wider and more raised than the other.
Claim 11
Dependent Claim
15 words
A panel as claimed in claim 8 wherein the different sized ribs are non-uniformly distributed.
Claim 12
Dependent Claim
15 words
A panel as claimed in claim 7 including a woven scrim backing on the fabric.
Claim 13
Dependent Claim
29 words
A panel as claimed in claim 10 wherein the woven scrim backing is attached to the fabric in yet another needle-punching operation performed before the forming of the ribs.
Claim 14
Dependent Claim
37 words
A panel as claimed in claim 7 wherein said longitudinal edge portion of the board is relieved to the rear to said kerf to provide clearance for a central web portion of a generally H-shaped mounting spline.
Claim 15
Dependent Claim
57 words
An acoustical wall panel comprising an elongated generally rectangular sound absorbent fabricated fibrous board, and a fabric adhered to a front face of said board, said fabric being formed of non-woven staple fibers needle-punched in a first needle-punching operation and having raised linear ribs thereon formed in another needle-punching operation, the ribs extending longitudinally of the panel.
Claim 16
Dependent Claim
57 words
An acoustical wall panel comprising an elongated generally rectangular sound absorbent fabricated fibrous board, and a fabric adhered to a front face of said board, said fabric being formed of non-woven staple fibers needle-punched in a first needle-punching operation and having raised linear ribs thereon formed in another needle-punching operation, the ribs extending longitudinally of the panel.
Claim 17
Dependent Claim
31 words
