Abstract

A belt skiving apparatus and method in which a free-standing blade-carrying carriage is employed which does not require a guiding base. The carriage has a pair of rollers defining a nip into which a belt end to be skived is passed. The rollers press together about the belt end to securely grip the belt. One of the rollers is toothed to provide a non-slip engagement with the surface of the belt and at least one of the rollers is driven, preferably manually, through a crank arm. Rotation of the rollers advances the carriage relative to the belt to advance the carriage across the width of the belt. As the carriage is advanced, the belt is passed through the rollers and through a cutting blade disposed adjacent the rollers. As the carriage is advanced along the width of the belt, the blade slices a thin strip of the upper portion of the belt adjacent its upper face from the remainder of the belt. The thin strip that is removed is the portion of the belt that was punctured by the teeth of the driving roller. The carriage is preferably wheel mounted to roll across the width of the belt directly on a support surface, without the need for a guiding base.

Claims9

Dependent claims

A skiver apparatus for cutting grooves in conveyor belts, the skiver apparatus comprising:

a traveling carriage including a body having a rearward end and a forward end, and a side wall extending between the ends of the body;
a belt cutting blade extending away from the side wall of the carriage body for cutting a groove in a conveyor belt as the carriage body is advanced in a forward direction along the belt;
a pair of rollers that are spaced from each other and which extend away a predetermined distance from the side wall of the carriage body to distal ends thereof spaced from the side wall, at least one of the rollers being movable towards the other roller for adjusting the space therebetween for clamping onto the belt and traveling thereacross as the rollers are rotated;
and
a belt receiving opening at the predetermined distance from the carriage body side wall between the distal ends of the rollers with the belt receiving opening generally lying in a plane that extends between the rollers and toward and away from the side wall of the carriage body and toward the forward and rearward ends of the carriage body to allow the belt to be fed along the plane toward the side wall, wherein the belt extends away from the body side wall and out from the belt receiving opening, and the rollers are clamped and advanced along said plane as the carriage travels in the forward direction.
