Patent ID: 8677871

Claim:
Device for arranging a belt layer provided with parallel cords on a building drum, comprising: a cutting device for cutting the belt layer from a web at a cutting angle along a cutting line along a cord, for obtaining a substantially parallelogram-shaped belt layer having a leading diagonal side and a trailing diagonal side and cords at a cord angle that is substantially parallel to the diagonal sides and the cutting angle; a belt layer length sensor for measuring the belt layer length; a control computer, operationally coupled to the belt layer length sensor and provided with a memory for storing a set cord angle, belt layer width and belt layer length; an applicator for arranging the belt layer on the building drum with the trailing diagonal side parallel to the leading diagonal side, and wherein the applicator is operationally coupled to the control computer for receiving control signals from said control computer; wherein the cutting device is provided with a circular blade that is supported on and surrounds a blade axle, wherein the cutting device comprises a rotation driving device for having the cutting angle adjusted during cutting, wherein the rotation driving device is operationally coupled to the control computer for adjusting the cutting angle, wherein in sideward direction with respect to the cutting line the blade is freely slidable over the blade axle during cutting, and wherein the cutting device comprises a displacement detector for detecting changes in the sideward position of the blade, wherein the control computer is provided with software routines for calculating the course of the cutting line from the determinations of the blade position during cutting, comparing the cutting line with the set cord angle and belt layer width, and the measured belt layer length with the set belt layer length and for giving of reference values and control signals based on the reference values and wherein the displacement detector is operationally coupled to the control computer, for when detecting a change in the sideward position having the control computer give a control signal to the rotation driving device for adjusting the cutting angle.
