Title (EN) IMPROVED CONVEYOR BELTING AND METHOD OF MANUFACTURE
(FR) BANDE TRANSPORTEUSE AMELIOREE ET SON PROCEDE DE FABRICATION
Abstract:
(EN) A double-scrim belting (10) is described having a first woven scrim (12) and a spaced apart and substantially parallel second woven scrim (14) connected by staple fibers (16) consolidated together through entanglement and integrated with the scrims through entanglement, both entanglements being of the kind typically produces by needling. If desired, a non-woven web of staple fibers is needled to the outer surfaces of the scrims and the thusly formed belting is completely encapsulated in a matrix of elastomeric material (36). To further strengthen the connection between the scrims (12, 14), the scrims are additionally joined together by binder members (42) which extend in a direction of the thickness of the belting. If the belting is intended to be used to convey food grade products, preferably an antibacterial agent is incorporated into the elastomeric material to inhibit bacterial growth.
(FR) L'invention concerne une bande à double renfort tissé (10), le premier renfort tissé (12) et le second renfort tissé (14), par rapport au premier et sensiblement parallèle à celui-ci, étant reliés entre eux par des fibres discontinues (16) consolidées au moyen d'un enchevêtrement et intégrées aux renforts à l'aide d'un autre enchevêtrement, ces deux enchevêtrements appartenant à la catégorie des enchevêtrements habituellement obtenus par aiguilletage. Le cas échéant, une bande non-tissée de fibres discontinues est aiguilletée sur les surfaces extérieures des renforts, la bande transporteuse résultante étant alors entièrement encapsulée dans une matrice de matériau élastomère (36). Afin de renforcer encore les liens entre les renforts (12, 14), on peut les relier en plus par des éléments de liaison (42) qui s'étendent dans une direction de l'épaisseur de la bande transporteuse. Si l'on désire utiliser cette bande pour transporter des produits de type alimentaire, il est préférable d'incorporer un antibactérien au matériau élastomère afin d'empêcher la croissance bactérienne.
