Embodiment Construction
[0133] In the figures, numeral 999 generally designates feeding means for the continuous elongated element 900 .
[0134] Illustratively, the continuous elongated element 900 consists of a strip-like element made of a homogeneous raw elastomeric compound. Exemplarily ( figure 2 ), perpendicular to the advancing direction 100 of the continuous elongated element (at figure 2 , with a direction into the plane of the paper) the cross-section 200 of the continuous elongated element is generally rectangular (ignoring possible surface imperfections, not shown), for example a rectangle with a long side about 20 cm long and a short side about 3 cm high.
[0135] Exemplarily, the feeding device 999 comprises a first roller 1 and a second roller 2 arranged side by side and each having an axis of rotation 101, 102 parallel to each other (in figure 1 identified by the symbol +), wherein the first roller 1 can move relative to the second roller 2 along a displacement direction 103 in or...

Abstract
A feeding device (999) and a method for feeding a continuous elongate element (900) in which the continuous elongate element is clamped between a first roller (1) and a second roller (2) arranged side by side by means of a push actuator (5), the first roller and the second roller having respective axes of rotation (101, 102) substantially parallel to each other, in which the first roller (1) and the second roller (2) are rotated by a motor (8) and a transmission (14), the first roller (1) and the second roller (2) are driven by a motor (8) and a transmission (14) to advance the continuous elongated element in order to feed the continuous elongated element at a feed speed to a feed point (A), the respective rotational speeds of the first roller (1) and the second roller (2) being controlled by the motor (8) and the transmission (14), in order to limit or prevent a change in the respective rotational speed due to the action of the continuous elongate element (900) on at least one of the first roller (1) and the second roller (2).
Description
technical field [0001] The invention relates to a feeding device and a method for feeding continuous elongated elements, in particular for the production of tyres. Background technique [0002] In the context of the tire production process, continuous elongated elements, typically entirely elastomeric compounds or comprising elastomeric compounds in combination with other elements, are usually processed or manipulated (eg strip-like elements). [0003] The terms "feeding" and the like refer to conveying a continuous elongated element through a feed point for the purpose of any type of processing (e.g., mixing, extruding, cutting, unrolling or winding, coupling with other elements, calendering, etc.) . [0004] "Continuous elongated element" means a structurally bonded element whose longitudinal dimension (defining length) is substantially greater than the remaining dimensions (defining width and thickness) and having any shape (e.g., rectangular, circular, oval, irregular, ...
