A method and apparatus for forming an apex or an apex in combination with a bead, the method comprising the steps of: winding a strip of rubber onto a rotatable platen to form an apex, wherein the rotatable platen may further include a radially expandable bead chuck for supporting a bead. The rotatable platen may optionally include a nonstick coating such as titanium nitride and optionally include one or more radially oriented bars. The optional one or more radially oriented bars may be movable into a first position flush with the outer surface of the platen, and movable into a second position that preferably is nonflush and protrudes from the outer surface of the platen. The rotatable platen is further optionally retractable from the bead chuck to facilitate removal of the apex from the apparatus.

Method and apparatus for forming an apex

A method and apparatus is provided for separating two or more annular members such as bead assemblies or bead and apex assemblies. First, a flexible member is inserted into the annulus of the annular members. Next, the flexible member is inflated until the outer surface of the flexible member contacts the inner diameter of the annular member. Then the flexible member is axially expanded until the annular members are separated. Then the flexible member is deflated so that the annular members can be removed.

Tire bead separation method and device

A method of forming an elastomeric tire component is provided, comprising the following steps. An apparatus is provided which includes a rotating applicator head and a non-rotating portion. The non-rotating portion has an internal channel having a first end in fluid communication with a gear pump and a second end in fluid communication with a first channel of the rotating applicator head. The first channel is substantially aligned with the Z axis. The rotating applicator head further includes a second channel in fluid communication with the first channel, and wherein the second channel is oriented at an angle with respect to a Y axis and is in fluid communication with a nozzle. The method further includes pumping a strip of elastomeric material through said internal channel and then into said first and second channel, and then through an outlet of said nozzle onto a surface. The apparatus further comprising a tongue assembly rotatably mounted to the applicator head and being positioned adjacent said nozzle, wherein said tongue compresses said strip of elastomeric material against said surface.

Method for forming elastomeric tire component and a tire

A method and device is provided for reducing the tension on an elastomeric feed strip. The method includes providing a device for engagement with the feed strip, pushing the feed strip forward by the device when the feed strip stops or when the tension exceeds a certain value, and then pushing the strip in the direction of travel.

Device for reducing the tension on an elastomeric feed

A method for grounding reinforcement ( ) and composites ( ) on a calender line reduces static build up on the composite ( ), and makes it possible to subject a wire reinforced composite to electron beam processing (EBP). The method employs a slip ring ( ) attached to rolls which contact composite ( ) on the calender ( ), and reinforcement ( ) before it reaches the calender ( ), wherein the slip ring ( ) rotates with the rolls while the rolls are working polymer into the reinforcement, and a terminal ( ) connected to the slip ring ( ) remains stationary, and the terminal ( ) is attached to ground ( ). The method effectively grounds the composite as well as the reinforcement to prevent electrical discharge during EBP.
