Abstract: A method and apparatus are provided for automatic and hands-free threading of an elastomeric mix into a calender set of rolls comprising one or more pairs of rolls that have a nip between them. A stripper roll is positioned next to one of the rolls forming the nip and is rotated so that the outer surface of the stripper roll moves in a direction opposite to the outer surface of the adjacent roll. The stripper roll removes all or a desired portion of the elastomeric mix from the adjacent roll and causes the same to transfer to another roll. Variables such as e.g., the relative surface speed of the stripper roll, diameter of the stripper roll, and distance of the outer surface of the stripper roll from the adjacent roll can be manipulated to control the amount of the elastomeric mix that is stripped by the stripper roll.

The tip of the wedge may be placed into contact with the first roll. The wedge may also have an arcuate surface, shaped e.g., like the outer surface of the first roll, and positioned a predetermined distance from the outer surface of the first roll.

Abstract: A tire is described that includes a casing defining a cavity and equipped to receive an object, such as an electronic circuit, for example, through use of a two-part attachment, such as a touch-close attachment, of which a first part is fixed to a wall of the casing and a second part can be joined to the first part when placed in contact with the first part to keep the object on the casing in a service position.
