Abstract: Disclosed is an extrusion mold for tire treads that extrudes semi-finished tires, for example, a cap tread, a wing tread and a sub tread. The preformer includes a first preformer die-holder having a wing tread flow-path, a cap tread flow-path and a sub tread flow-path formed therein, a second preformer die-holder, and a final die inserted into the second preformer die-holder and ejecting an extrudate. The improvement of the preformer die includes a middle upper preformer die and a middle lower preformer die between the first and second preformer die-holders to be brought into contact with the final die. The middle upper preformer die is formed with a wing tread-connecting guide groove and a cap tread-connecting guide groove communicating with the wing tread flow-path and the cap tread flow-path, respectively. The middle lower preformer die is formed with a sub tread-connecting guide groove communicating with the sub tread flow-path.

Abstract: A wafer carrier having an anti-slip structure formed on outward surface portions of side plates of the wafer carrier. The anti-slip structure may be composed of at least one of several shapes or structures such as grooves, round shape projections, and acute angle shaped projections, each which is formed on both the outward surface portions. The wafer carrier having such an anti-slip structure prevents the wafer carrier from slipping or falling while the wafer carrier is being transported.
