Abstract: A combination seal is attached to a bearing comprising a fixed element and a rotating element which rotate relative to each other, so as to seal an inner side and an outer side of the bearing. The combination seal is comprised of a seal ring and a slinger. The seal ring is comprised of a reinforcing ring and an elastic seal supported by the reinforcing ring. A leading end side of the elastic seal, supported by the reinforcing ring extending toward the slinger, is brought into contact with a surface of the slinger, which is opposite to the seal ring, when the combination seal is attached to the bearing. During a combining work process, when combining the seal ring and the slinger to form the combination seal, a seal lip does not turn over and the seal lip can be held toward a predetermined direction without using a specific jig during the combining work process and without being particularly careful during performance of the combining work process.

Abstract: A glass sheet G, which has been heated to the bending temperature by a heating furnace 12, is preliminary bent in the course of being conveyed to a bending position by a roller conveyer for preliminary bending 20. When the glass sheet thus preliminary bent is put on a press ring at the bending position, the glass sheet is pressed against the bending surface 26 of a mold 24 by upward movement of the press ring 22 to be bent so as to have a desired radius of curvature. After that, the press ring 22 is moved toward an air-cooling/tempering apparatus 16. When the press ring 22 is introduced into a certain tempering position S, cooling air is ejected from an upper blowing head 30 and a lower blowing head 32 toward the glass sheet G to air cool and temper the glass sheet G.
