Abstract:
A cutting device and method for a tire reinforcement cord, the cutting device including a knife mounted on the periphery of a first rotary disk, and a second rotary disk mounted opposite the first rotary disk, and in which the knife of the first disk and the second disk are brought into cutting contact with the reinforcement while driving the first and second disks in rotation, the cutting device being preset so that, on cutting, the knife engages with said reinforcement, while the peripheral speed of said first and second rotary disks is close to the linear speed of the reinforcement.
Abstract:
An oscillating arm apparatus for manufacturing a tire reinforcement from a single cord in which the cord is deposited in contiguous arches on a rigid core by a system of arms arranged in series conveying an eyelet in such a way as to allow it to traverse a core and thus deposit adjacent arches.
Abstract:
A cutting device and method in which a reinforcement is guided to a cutoff point where it is cut by a knife driven by a rotary shaft and carried along a closed path which brings the knife into cutting relationship with the reinforcement during predetermined cycles.
Abstract:
An apparatus for manufacturing a tire reinforcement from a cord, cooperating with a substantially toroidal form on which arches of the cord are deposited according to a desired trajectory for the cord on the surface of the form, the apparatus having depositing members arranged on a support, the depositing members including a guide member in which the cord may slide freely, a mechanism for actuating the guide member in a cyclical, to-and-fro, movement, to bring the guide member in successive oscillations into the vicinity of each of the desired ends for the cord in the trajectory. The apparatus further includes a first motor imparting the desired movements to the actuating mechanism and a second motor for imparting to the depositing member support a cyclical movement synchronized with the actuating mechanism, allowing deflection of the final trajectory of the cord on the form.
