Abstract
Abstract A seamless endless belt for battery pasting machines, particularly lead batteries, comprising an outer endless woven fabric (11), consisting of 1 to 3 plies, and an inner backing layer formed by multi-strata of non-woven webs (12), consisting of synthetic staple fibres, and of light woven meshes (13). The outer fabric (11), the non-woven webs (12) and the light woven meshes are bound together by needling.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
62 words
A seamless endless belt for battery pasting machines comprising two layers: a) an outer layer formed by 1 to 3 plies of an endless woven fabrics, and b) an inner backing layer formed by multi-strata of non-woven webs made of synthetic staple fibres and light woven meshes, the outer layer and the multi-strata of the inner layer being bound together by needling.
Claim 2
Dependent Claim
62 words
A seamless endless belt for battery pasting machines comprising two layers: a) an outer layer formed by 1 to 3 plies of an endless woven fabrics, and b) an inner backing layer formed by multi-strata of non-woven webs made of synthetic staple fibres and light woven meshes, the outer layer and the multi-strata of the inner layer being bound together by needling.
Claim 3
Dependent Claim
17 words
A seamless endless belt according to claim 1, wherein the outer layer is made of cotton threads.
Claim 4
Dependent Claim
23 words
A seamless endless belt according to claim 1, wherein the outer layer is made of synthetic carded threads of polyester or polyamide fibres.
Claim 5
Dependent Claim
30 words
A seamless endless belt according to any of the preceding claims, wherein the non-woven webs are made of synthetic staple fibres and the light meshes of high tenacity polyester multifilaments.
Claim 6
Dependent Claim
21 words
