COURROIE TRANSPORTEUSE OU COURROIE DE TRANSMISSION AVEC BORD'PROTEGE.
Dans les courroies transporteuses ou courroies de transmission usuelles, réalisées en caoutchouc et contenant une couche intermédiaire ré- sistant à la traction, il arrive fréquemment que les bords se déchirent par le fait d'un effort irrégulier. Dans le but d'empêcher ce fait, il est connu de réaliser de manière spéciale les bords des courroies. A cette fin, les bords de la courroie sont revêtus d'un tissage en textile qui peut être dis- posé au-dessus des plaques de recouvrement constituées par du caoutchouc ou qui peut être noyé dans celles-ci. Cependant ces. mesures de protection pour les bords se sont avérées insuffisantes.
Suivant l'invention, la protection des bords, constitués par des fils textiles, est réalisée par des fils en une matière synthétique présen- tant une grande résistance à la traction et à l'usure, telle qu'une polyami- de, un polyuréthane ou un polyester. La nouvelle protection des bords peut être disposée avantageusement sous forme de torons, formés par la matière synthétique mentionnée, dans les zônes du bord des courroies. Cependant, il est également possible de revêtir les bords avec un tissage qui est constitué totalement ou partiellement par des fils en matière synthétique des types décrits. Dans ce cas,les fils en matière synthétique peuvent être disposés, soit dans le sens de la couche intermédiaire de support, résistant à la traction, de la courroie, soit dans un sens perpendiculaire ou de biais à celle-ci.
Cette dernière disposition présente l'avantage supplémentaire que les zônes de bord de la courroie sont maintenuesdans le sens transversal.
En comparaison avec les courroies connues, les bords des courroies suivant l'invention présentent une résistance considérablement accrue qui prolonge leur vie.
Deux formes de réalisation, données à titre d'exemple non limi- tatif, sont représentées aux dessins ci-annexés :
<Desc/Clms Page number 2>
1 représente les couches intermédiaires résistant à la traction et 2 représente les plaques de recouvrement en caoutchouc de la courroie. Sui- vant la fig. 1, les torons 3, constitués par un polyuréthane et servant de protection pour les bords, sont disposés dans les zônes-du bord de la cour- roie. Suivant la fig. 2, les bords de la courroie sont revêtus de bandes de matière 4 dont les fils sont constitués par une polyamide.
REVENDICATIONS.
1.- Courroie transporteuse ou courroie de transmission contenant une couche intermédiaire résistant à la traction et dont les bords sont pro- tégés, caractérisée par le fait que la protection des bords est constituée par une matière synthétique présentant une haute résistance à la traction et à l'usure, telle qu'une polyamide, un polyuréthane ou un polyester.

CONVEYOR BELT OR TRANSMISSION BELT WITH PROTECTED EDGE.
In conventional conveyor belts or transmission belts, made of rubber and containing a tensile-resistant intermediate layer, it frequently happens that the edges tear due to an irregular force. In order to prevent this fact, it is known to make the edges of the belts in a special way. To this end, the edges of the belt are covered with a textile weave which can be arranged over the cover plates made of rubber or which can be embedded in them. However these. protective measures for the edges proved insufficient.
According to the invention, the protection of the edges, formed by textile threads, is carried out by threads made of a synthetic material exhibiting great resistance to traction and to wear, such as a polyamide or a polyurethane. or a polyester. The new edge protection can advantageously be arranged in the form of strands, formed by the synthetic material mentioned, in the zones of the edge of the belts. However, it is also possible to coat the edges with a weave which consists wholly or partially of synthetic threads of the types described. In this case, the son of synthetic material may be arranged either in the direction of the intermediate support layer, resistant to traction, of the belt, or in a direction perpendicular or obliquely thereto.
The latter arrangement has the additional advantage that the edge zones of the belt are maintained in the transverse direction.
In comparison with the known belts, the edges of the belts according to the invention have a considerably increased resistance which prolongs their life.
Two embodiments, given by way of non-limiting example, are shown in the accompanying drawings:
<Desc / Clms Page number 2>
1 represents the tensile-resistant intermediate layers and 2 represents the rubber cover plates of the belt. Following fig. 1, the strands 3, formed by a polyurethane and serving as protection for the edges, are arranged in the zones of the edge of the belt. According to fig. 2, the edges of the belt are coated with strips of material 4, the threads of which consist of a polyamide.
CLAIMS.
1.- Conveyor belt or transmission belt containing an intermediate layer resistant to traction and whose edges are protected, characterized in that the edge protection consists of a synthetic material having high tensile strength and resistance to wear and tear, such as polyamide, polyurethane or polyester.
