A belt skiving apparatus (120) and method in which a free-standing blade- carrying carriage (122) is employed without a guiding base. The carriage has one or two pairs of rollers (124a, 126a, 124b, 126b) defining a nip(s) into which a belt end (125) to be skived is passed. The rollers press together about the belt end to securely grip the belt, with at least one of the rollers being driven through a crank arm (138). Rotation of the rollers advances the carriage relative to the belt and across the width of the belt. As the carriage is advanced, the belt (128) is passed through the rollers and through a cutting blade (134) disposed adjacent the rollers, with the blade slicing a thin strip (131) of the upper portion of the belt adjacent its upper face (130) from the remainder of the belt. An adjustable fence (200) is used to vary width of cut.

Dispositif (120) et procédé destinés à doler une courroie, dans lesquels on utilise un chariot (122) autonome, porteur de lame, sans base de guidage. Ce chariot possède une ou deux paires de rouleaux (124a, 126a, 124b, 126b) délimitant un (des) pincement(s) dans lequel (lesquels) on fait passer une extrémité (125) de courroie à doler. Les rouleaux se resserrent sur l'extrémité de la courroie afin de la retenir fermement, l'un au moins des rouleaux étant entraîné par un bras (138) de manivelle. La rotation des rouleaux fait avancer le chariot par rapport à la courroie et sur la largeur de celle-ci. Lorsque le chariot avance, la courroie (128) passe entre les rouleaux et à travers une lame coupante (134) adjacente à ceux-ci et qui tranche une bande (131) mince dans la partie supérieure de la courroie adjacente à la face supérieure (130) de celle-ci, à partir du reste de la courroie. On utilise une barrière (200) réglable pour varier la largeur de coupe.
