PURPOSE:To generate gas pressure simply and economically by interposing push- down rolls between driving rolls for transferring weight goods such as slab and pushing down the push-down rolls by dead load of the weight goods to compress subber bellows. CONSTITUTION:When slab 11 of big weight is moved on driving rolls 1 which can not move up and down and are disposed below a conveyer line, push-down rolls 2 positioned at the central portion between each driving roll 1 and above the driving rolls are pushed down by the dead load of the slab 11. Therefore, a rubber bellows 5 is compressed against a compression coil spring 6 through frames 3 disposed on both sides of the push-down roll 2, so that the lower surface of the slab 11 is brought into contact with the driving rolls 11 to be transferred to the next process, and the air sucked in the rubber bellows 5 from a suction pot is compressed to be exhausted from an outlet 8. Thus, every time compression and restoration of the rubber bellows 5 is repeated with movement of the slab 11, pressurized gas is generated or exhausted. |
