CA 2251005

A belt (10) for use in a conveyor system has ribs (12, 14, 23, 24, 26, 30) to aid in the training of the belt. The invention comprises a belt (10) with a body (18) having an inner surface (16), an outer surface, and a first set of longitudinal ribs (12, 14, 23) disposed on the inner surface (16) of the belt. The ribs function to lessen the surface area of the belt contacting a roller (32) of the system during the training period. Accordingly, the new belt adheres to the rollers of the conveyor system less aggressively, reducing lateral coplanar forces having the potential to damage the belt and/or the conveyor system. The height of the ribs with respect to the body diminishes over time due to normal frictional wear during the use of the belt in the conveyor system. In some embodiments, the belt includes a second set of ribs (24, 26, 30) disposed on the outer surface (28) of the belt. The height of the second set of ribs with respect to the body also diminishes over time due to normal frictional wear during the use of the belt in the conveyor system. The sets of ribs may comprise two ribs (12, 14, 24, 26) running along the edges (20, 22) of the belt. A wider belt may require additional ribs (23, 30) located between the two edge ribs. The belt may be used in a system of rollers (32) and training guides (34). The training guides (34) function to maintain the alignment of the belt with respect to the rollers.

Cette courroie (10) pour transporteur est pourvue de nervures (12, 14, 23, 24, 26, 30) servant d'auxiliaires d'entraînement. Le dispositif de l'invention consiste en une courroie (10) dont le corps (18) est constitué d'une face intérieure (16) et d'une face extérieure ainsi que d'un premier jeu de nervures longitudinales (12, 14, 23) disposées sur la face intérieure (16). Ces nervures sont destinées à alléger l'aire de surface de la courroie venant au contact d'un cylindre (32) lors de l'entraînement de la courroie. En conséquence, cette nouvelle courroie adhère moins fortement aux cylindres du transporteur, du fait d'une diminution des forces coplanaires susceptibles, en outre, d'endommager la courroie et/ou le transporteur. La hauteur des nervures par rapport au corps se réduit avec le temps en raison d'une usure normale de frottement. Dans certains modes de réalisation, la courroie possède un second jeu de nervures (24, 26, 30) disposées sur la face extérieure (28) et l'usure normale de frottement réduit également, dans ce cas, la hauteur des nervures par rapport au corps. Les jeux de nervures sont susceptibles de comporter deux nervures (12, 14, 24, 26) courant le long des bords de la courroie. Il peut être nécessaire, dans le cas d'une courroie de plus grande largeur, d'ajouter des nervures supplémentaires (23, 30) venant se placer entre les deux nervures de bordure. On peut employer cette courroie dans des systèmes à cylindres (32) et guides d'entraînement (34). Ces derniers servent à maintenir la courroie dans l'alignement des cylindres.
