Claim:
1. A cutting device for cutting a reinforcing ply formed of a set of portions of thread, of given length, coated in a rubber compound, laid parallel to one another and making a given theoretical angle with a longitudinal direction of the ply, comprising: a first means able, without proceeding to cut the ply, to apply a first force and to estimate an actual angle of the threads with a longitudinal direction of the device, comprising a measurement wheel, mounted on a mobile support running on a straight rail, with a direction of the rail being orientable to a given angle with the longitudinal direction of the device, and able to follow a groove formed by a space between two mutually juxtaposed reinforcing threads when the support moves along the rail, and of which an axle, oriented substantially in a direction perpendicular to a plane formed by the direction of the rail and by the direction perpendicular to the plane of the ply, is free to move in said direction of the axle, and a second means able to apply a second force that is greater than the first force and to cut the ply at the actual angle estimated by the first means; wherein the first means further comprises; assessing means for assessing the distance covered by the support of the said wheel along the rail, assessment means for assessing the movement of the said wheel in the direction parallel to the direction of the axle, and calculation means able to determine a mean actual angle of the threads with the longitudinal direction.
