Method and apparatus for controlling a manufacturing process of components of a tyre for vehicle wheels
First Claim
1. A method for controlling a manufacturing process of components of a tyre for vehicle wheels, wherein at least one elongated element fed by a dispensing member is distributed onto a forming support by means of at least one pressing member acting on said at least one elongated element along a pressing direction, comprising the steps of:
- detecting with a predetermined frequency the value of a characteristic quantity indicative of the position of said at least one pressing member along said pressing direction;
comparing the detected value of said characteristic quantity with a threshold value; and
generating a warning signal when the detected value of said characteristic quantity exceeds said threshold value, including generating a warning signal in response to a single acceleration of the pressing member in excess of a threshold value indicating more movement of the pressing member than desired.

Abstract
A method for controlling a manufacturing process of components of a tire for vehicle wheels, wherein at least one elongated element fed by a dispensing member is distributed onto a forming support by means of at least one pressing member acting on the at least one elongated element along a pressing direction. The method includes the steps of substantially continuously detecting the value of a characteristic quantity indicative of the displacement of the at least one pressing member along the pressing direction, comparing the detected value of the characteristic quantity with a threshold value and generating a warning signal when the detected value of the characteristic quantity exceeds the threshold value. Such a control method allows the presence of possible deposition anomalies to be identified right from the deposition step of the elongated elements on the forming support so as to ensure ever higher quality levels in tires manufactured through continuous processes.

19. An apparatus for depositing at least one elongated element onto a forming support in a manufacturing process of components of a tyre for vehicle wheels, comprising:
-
a dispensing member arranged adjacently to said forming support and adapted to feed said at least one elongated element onto said forming support; at least one support element associated with said dispensing member; at least one device adapted to push said at least one support element against said forming support along a pressing direction; at least one pressing member integrally associated with said at least one support element at a free end thereof and adapted to distribute said at least one elongated element onto said forming support; a detecting device of a characteristic quantity indicative of the position of said at least one pressing member along said pressing direction during the deposition of said at least one elongated element onto said forming support; wherein said detecting device comprises a device for generating an electric signal indicative of the position of said at least one pressing member along said pressing direction and a device for processing said electric signal; and wherein said device for processing said electric signal is configured to generate a warning signal in response to a single acceleration of the pressing member in excess of a threshold value indicating more movement of the pressing member than desired. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
