（4－3）
In addition, in described wrapping machine, the virtual face that comprises the crest line of fusing cutter 53 front ends is the thickness direction bending, circular arc camber predetermined radius along fusing cutter 53.
(5) variation
Fig. 6 is the block diagram of fusing cutter 53 of transverse sealing mechanism 17 of the wrapping machine of variation.In Fig. 6, fusing cutter 53 has the effective cutter 531 that consists of central portion, the invalid cutter 532,533 that consists of two ends.Effectively cutter 531 is the parts of tubular membrane Fm of in fact fusing.Invalid cutter 532,533 function of tubular membrane Fm that do not fuse, and have just in case protect the function of the blade 531a of effective cutter 531 when effectively cutter 531 collides sealing surface.
Specifically, the front end of the blade 533a of the blade 532a of invalid cutter 532 and invalid cutter 533 is only given prominence to C than the blade 531a of effective cutter 531.C=0.5mm in this embodiment, in addition, outstanding outshot is that radius is the circular arc of 0.5mm, and has improved intensity and abrasion resistance properties.
So even the situation of effective cutter 531 and sealing surface (for example with reference to Figure 11 A) collision of relative the second clips 51b occurs, also that the blade 532a of invalid cutter 532 and the blade 533a of invalid cutter 533 first encounter sealing surface, so can avoid the blade 531a of effective cutter 531 to collide the situation of sealing surface.The blade 531a that therefore, can prevent effective cutter 531 produces breach and breaks etc.
The second embodiment
In the first embodiment, a pair of sealing contained side rotates the limit and contacts with tubular membrane Fm with arc surface, but is not limited to this.At this, the first clips and the second clips are approached repeatedly by rotational motion and other structures of separating describe.
(1) transverse sealing mechanism 117
Fig. 7 carries out the first clips 151a of rotational action and the lateral plan of the second clips 151b in the transverse sealing mechanism 117 of the wrapping machine of the second embodiment.In addition, due to except transverse sealing mechanism 117, identical with the first embodiment is so omitted their description.In addition, the track that has represented clips 151 rotational action that dot in Fig. 7.
The second embodiment has following different from the first embodiment: the first clips 151a and the second clips 151b rotate in the mode of describing D shape track across tubular membrane Fm in the plane; Fusing cutter 153 comprises primary heater 153h; Stationary knife 155 comprises secondary heater 155h.
In addition, control part is controlled respectively primary heater 153h and secondary heater 155h individually, and fusing cutter 153 and stationary knife 155 are adjusted to respectively different fusing-off temperatures.
In addition, the control part difference is control heater 51h individually, and each position of the first clips 151a and the second clips 151b is adjusted to respectively different seal temperatures.
Fig. 8 is the action timing diagram of the first clips 151a and the second clips 151b.In Fig. 8, control part is regulated the action of fusing cutter 153 and stationary knife 155.For example when the first clips 151a and the second clips 151b rotate in D shape mode, after the first clips 151a and the second clips 151b begin to clamp tubular membrane Fm, release fusing cutter 153, tubular membrane Fm is fused between cutter 153 and stationary knife 155 by being pressed in, tubular membrane Fm begins to fuse, before thereby the first clips 151a and the second clips 151b separately finish to clamp tubular membrane Fm, fusing cutter 153 is retreated, finish the fusing to tubular membrane Fm.
That is to say, make fusing more late the zero hour than sealing the zero hour, and make the fusing tc finish time more Zao than the sealing ts finish time.In this case,, be cut off between bag and tubular membrane Fm and separate, and bag fell when the moment, ts separated as the first clips 151a and the second clips 151b.
