Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
83 words
An ironing press comprising buck means having a convex curvature and head means having a concave curvature throughout their coacting surfaces, one of said means having its coacting surface of a flatter curvature than the other, and a pressure mechanism for pressing said means together, one of said means being of resilient material, and the other of said means being rigid, to produce a relative gliding motion between the ironing surfaces of the buck and head means to stretch the material being ironed.
Claim 2
Dependent Claim
83 words
An ironing press comprising buck means having a convex curvature and head means having a concave curvature throughout their coacting surfaces, one of said means having its coacting surface of a flatter curvature than the other, and a pressure mechanism for pressing said means together, one of said means being of resilient material, and the other of said means being rigid, to produce a relative gliding motion between the ironing surfaces of the buck and head means to stretch the material being ironed.
Claim 3
Dependent Claim
83 words
An ironing press comprising buck means having a convex curvature and head means having a concave curvature throughout their coacting surfaces, one of said means having its coacting surface of a flatter curvature than the other, and a pressure mechanism for pressing said means together, one of said means being of resilient material, and the other of said means being rigid, to produce a relative gliding motion between the ironing surfaces of the buck and head means to stretch the material being ironed.
Claim 4
Dependent Claim
83 words
An ironing press comprising buck means having a convex curvature and head means having a concave curvature throughout their coacting surfaces, one of said means having its coacting surface of a flatter curvature than the other, and a pressure mechanism for pressing said means together, one of said means being of resilient material, and the other of said means being rigid, to produce a relative gliding motion between the ironing surfaces of the buck and head means to stretch the material being ironed.
Claim 5
Dependent Claim
26 words
An ironing press according to claim 1 in which the buck means is of resilient material and is of a flatter curvature than the head means.
Claim 6
Dependent Claim
45 words
An ironing press according to claim 1 in which at least one of said means is constructed as a carrier having uniform rigidity and including means whereby the force produced by the pressure mechanism is effective in a longitudinal plane which vertically bisects the carrier.
