Abstract
Abstract Thermoplastics articles having surfaces laminated to cloth are made without distortion of the cloth by using a melded cloth, that is to say a cloth composed of contiguous conjugate fibres fused together at points where they touch one another. The articles can be made by moulding thermoplastics materials onto melded cloth inserted into a mould.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
61 words
A molded thermoplastics shaped article having a surface region keyed into a piece of cloth which is non-woven cloth having a thickness of at least 0.6 mm and weight of 50 to 250 g/m 2 wherein the cloth comprises contiguous fibres at least some of which are fused together at at least some of the points where they touch one another.
Claim 2
Dependent Claim
61 words
A molded thermoplastics shaped article having a surface region keyed into a piece of cloth which is non-woven cloth having a thickness of at least 0.6 mm and weight of 50 to 250 g/m 2 wherein the cloth comprises contiguous fibres at least some of which are fused together at at least some of the points where they touch one another.
Claim 3
Dependent Claim
110 words
A molded thermoplastics shaped article having a surface exhibiting permanent radiused curves fusion-bonded to a piece of cloth which is incompletely penetrated by the thermoplastics so as to retain its cloth-like feel, said cloth having a thickness of at least 0.6 mm and a weight of 50 to 250 g/m 2 and comprising contiguous fibres at least some of which are fused together at at least some of the points where they touch one another, said article having been formed by positioning the cloth against an article-defining contoured surface of a mold and introducing the thermoplastics material into the mold in a flowable condition so as to contact the cloth.
Claim 4
Dependent Claim
110 words
A molded thermoplastics shaped article having a surface exhibiting permanent radiused curves fusion-bonded to a piece of cloth which is incompletely penetrated by the thermoplastics so as to retain its cloth-like feel, said cloth having a thickness of at least 0.6 mm and a weight of 50 to 250 g/m 2 and comprising contiguous fibres at least some of which are fused together at at least some of the points where they touch one another, said article having been formed by positioning the cloth against an article-defining contoured surface of a mold and introducing the thermoplastics material into the mold in a flowable condition so as to contact the cloth.
Claim 5
Dependent Claim
111 words
An injection molded thermoplastics furniture component having a surface exhibiting permanent radiused curves fusion-bonded to a piece of cloth which is incompletely penetrated by the thermoplastics so as to retain its cloth-like feel, said cloth having a thickness of at least 0.6 mm and a weight of 50 to 250 g/m 2 and comprising contiguous fibres at least some of which are fused together at at least some of the points where they touch one another, said article having been formed by positioning the cloth against an article-defining contoured surface of a mold and injecting the thermoplastics material into the mold in a flowable condition so as to contact the cloth.
Claim 6
Dependent Claim
111 words
An injection molded thermoplastics furniture component having a surface exhibiting permanent radiused curves fusion-bonded to a piece of cloth which is incompletely penetrated by the thermoplastics so as to retain its cloth-like feel, said cloth having a thickness of at least 0.6 mm and a weight of 50 to 250 g/m 2 and comprising contiguous fibres at least some of which are fused together at at least some of the points where they touch one another, said article having been formed by positioning the cloth against an article-defining contoured surface of a mold and injecting the thermoplastics material into the mold in a flowable condition so as to contact the cloth.
Claim 7
Dependent Claim
13 words
An injection-molded furniture component as in claim 3 which is a chair component.
