Disclosed is joining device for joining a trailing end of a first strip to a leading end of a second strip to form a tire component. The joining device includes a support member with a support surface and a retaining member with a retaining surface for retaining the second strip. The joining device is arranged for positioning the leading end of the second strip in a joining orientation in which said leading end is closer to the support plane than the rest. The joining device also includes a control unit for controlling a relative movement between the support member and the retaining member with a first component in a placement direction to place the leading end of the second strip and a second component in a joining direction to bring the leading end of the second strip into contact with the trailing end of the first strip.

Disclosed is a tire building apparatus and a method for joining or cutting tire components. The tire building apparatus includes a rocking member that is movable in a rocking plane in a rocking motion along a rocking line, a translation guide extending parallel to the rocking line and a carriage that is displaceable along the translation guide, wherein the rocking member has a convex edge that defines a minor arc of a circle and extends up to a rotation center, wherein the rocking member is supported by the carriage at the rotation center and is angularly displaceable with respect to the carriage about a rotation axis extending through the rotation center.

The installation comprises a preparation station for preparing strips by cutting a straight wire band, a jointing station arranged to butt-joint the strips obtained from the preparation station so as to form a reinforcing ply, and a station for turning over strips, which is interposed between the preparation station and the jointing station. The installation also comprises a first receiving surface, arranged to receive a strip, a second receiving surface associated with a reversing device which is arranged to transfer a strip from said first receiving surface to said second receiving surface, by thus turning over the strip. A gripping member is arranged to take a strip from the first or second receiving surface in order to allow the jointing station to selectively construct a reinforcing ply with a left-hand ply handle or with a right-hand ply angle.

A bleeder cord affixing device is made up of an affixing roller extending in a width direction of the treatment member and adapted to be pressed into the treatment member being moved, thereby to be rotated; and a roller moving mechanism that moves the affixing roller to and away from the treatment member. The roller moving mechanism operates to move the affixing roller to a pressed position urged to the treatment member, with a result that the affixing roller is caused to be rotated due to the movement of the treatment member at the pressed position and attaches the rubber member to the treatment member under the pressing force, and then presses the bleeder cords onto the treatment member to continuously affix the bleeder cords onto the surface of the treatment member.

Disclosed is joining device for joining a trailing end of a first strip to a leading end of a second strip to form a tire component. The joining device includes a support member with a support surface and a retaining member with a retaining surface for retaining the second strip. The joining device is arranged for positioning the leading end of the second strip in a joining orientation in which said leading end is closer to the support plane than the rest. The joining device also includes a control unit for controlling a relative movement between the support member and the retaining member with a first component in a placement direction to place the leading end of the second strip and a second component in a joining direction to bring the leading end of the second strip into contact with the trailing end of the first strip.

A device for manufacturing a multiple layer rubber strip including a first rubber strip and a second rubber strip, the device includes a first rubber extruder for extruding the first rubber strip, a second rubber extruder for extruding the second rubber strip, a first conveyor for conveying the first rubber strip extruded from the first extruder to a downstream side in a convey direction, and a second conveyor for conveying the second rubber strip extruded from the second extruder to a downstream side in the convey direction. The second conveyor is located upwardly of the first conveyor and has a downstream conveyor end which positions above a conveying surface of the first conveyor such that the second rubber strip delivered from the downstream conveyor end meets and overlaps the first rubber strip on the first conveyor at a joining location to form the single multiple layer rubber strip.

Cord ply joiner for a tire includes a first pressurizer having first pressing member and first pressure receiving member in upper and lower sides, and a second pressurizer having second pressing member and second pressure receiving member in the upper and lower sides. A first code ply positioning mechanism positions a first code ply by bringing a tail end of the first code ply into contact with a side surface of the second pressure receiving member, a first code ply fixing mechanism lowers the cord end pressing member so the first cord ply is fixed, and a second code ply positioning mechanism positions the tip of the second code ply by bringing the tip into contact with a side surface of the cord end pressing member. The first pressurizer and the second pressurizer are brought close to each other, whereby a shearing force is applied to an overlapped portion.

The invention relates to a belt forming system comprises an upstream conveyor (33), a downstream conveyor (32) located downstream of the upstream conveyor, and a belt assembly system in communication with the upstream conveyor and the downstream conveyor. The belt assembly system comprises an arm (52), an actuator for moving the arm (54), and a holding component (53) coupled to the arm and adapted to move a strip section from the upstream conveyor to a desired position on the downstream conveyor such that the strip section is oriented at a predetermined angle on the downstream conveyor. In one embodiment, the belt forming system comprises a belt cutter (42). The invention also relates to a method for manufacturing at least a portion of a tire belt.
