Because when lapping dolly 2 commutates at two ends, the left and right sides, promptly when left end point and right endpoint commutation, owing to slow down or pause and can cause fibre web unnecessary, because first,

second convoying curtain

3,4 are at the uniform velocity state motion all the time, thereby just relate to recommend by the present invention first, second fibre

web compensation device

46,15 bear the responsibility stores unnecessary fibre web, discharge, specifically: when the large compensation roller 54 of second fibre web compensation device 15 is that carrier is when moving right with lapping cart 1, the compensation of first fibre web compensation device 46 is with 35 to move to left lateral synchronously, make first, second convoying

curtain

3,4 intersection is elongated, and this elongated part is the part of unnecessary fibre web just, thereby realizes by moving to right of large compensation roller 54 unnecessary fibre web being stored; Otherwise, when lapping dolly 2 breaks away from commutation with normal speed or with the acceleration lapping, large compensation roller 54 just is moved to the left, the compensation of this moment is with 35 to move to right lateral synchronously, the intersection each other of first,

second convoying curtain

3,4 is shortened, and this part that shortens for previous elongated part, that is to say that the intersection of first,

second convoying curtain

3,4 returns to normal length just, in this process, the fibre web that will before have been stored by large compensation roller 54 discharges.Say that briefly large compensation roller 54 moves to left, then for discharging fibre web; Large compensation roller 54 moves to right then for storing fibre web.Thereby the fibre web body 58 that lapping dolly 2 is spread out presents shape shown in Figure 8, and it is thin and thick middle exactly likes bread shape that this is shaped as both sides, can ensure that afterwards the needing machine acupuncture in road goes out rather desirable on-woven product.
