PURPOSE:To maintain sealing pressure constant by pressing a second roll supported by a slidable movable bearing with a force applying spring against a first roll supported by a fixed bearing on a frame of an apparatus for filling and packing liquid while a distance between both axes is fine-adjusted. CONSTITUTION:A pair of bearings 310, 320 are slidably inserted into a slit 210 of a frame 200 via blocks 560, 510. One of the bearings 310 is fixed to the block 560 and rotatably supports a shaft 410 with a first vertical sheet roll 420 attached. The other bearing 320 is slidably inserted into the slit 210 via the block 510 and rotatably supports the shaft. A coil spring 500 between the block 510 of the movable bearing 320 and the frame 200 constantly presses the movable bearing, while an adjustment screw 542 is screwed into a screw hole on a side opposite to the fixed bearing 310 to the block 510, thereby adjusting contact pressure of a second heat-sealing part 480. |
