At this, the edge sealing time interval refers to that fabric 100W is clamped in the time interval between the top of seal edge portion 123 and ultrasonic horn 133.In addition, fixing speed can be thought the transporting velocity of the fabric 100W in edge sealing time interval time interval in addition.
For example, as shown in Fig. 4 (a), Fig. 4 (b), in the situation that fixing speed is V1, conveying roller 110 constitutes: in the edge sealing time interval, the transporting velocity of fabric 100W reduces to the speed V2 lower than fixing speed V1.In this case, the transporting velocity V2 that is preferably the fabric 100W in the edge sealing time interval equates with the rotary speed of rotary body 120.
The variation 1 of fixing speed:
In situation shown in Fig. 4 (a), Fig. 4 (b), consider, for the production quantity of the absorbent commodity 1 that increases time per unit, fixing speed to be risen to V1' from V1.
In the variation 1 of fixing speed, as shown in Fig. 5 (a), Fig. 5 (b), conveying roller 110 constitutes: in the edge sealing time interval, the transporting velocity of fabric 100W reduces to the speed V2' lower than fixing speed V1'.At this, the difference of Vl ' and V2 ' is identical with the difference of Vl and V2.That is, the increase and decrease amplitude of the rotary speed of conveying roller 110 is certain.
Under these circumstances, when the rotary speed of rotary body 120 does not change, in the edge sealing time interval, because the transporting velocity of fabric 100W is different with the rotary speed of rotary body 120, therefore, may produce the wrinkle of fabric 100W and the position deviation of edge sealing position etc.
