The odor of the garbage would drift with the wind. Sometimes when the wind was heavy, the garbage in the car It will be blown out and it will not work. Nowadays, the garbage trucks are much advanced, and they are transformed from trucks. There is a big tail box, which can hold a lot of garbage. Then the door of the car can also be opened and closed. After loading the garbage, the door panels are closed and the odor is Garbage can't come out. This kind of garbage truck is working many times more efficiently than previous garbage trucks. It can serve many streets a day and keep every street in the city clean. Gear-hobbing machines use a rotating, multiple-tooth cutting tool called a hob for generating teeth on spur gears, worm gears, helical gears, splines, and sprockets. More gears are cut by hobbing than by other methods because the hobbing cutter cuts continuously and produces accurate gears at high production rates. In gear-making machines gears can be produced by cutting, grinding, or a combination of cutting and grinding operations.
