- said at least one non-rectilinear cutting sound 53 is embedded in the welding means 85 so as to substantially simultaneously produce the cutting and welding of each bag 1, the non-rectilinear cutting blade 53 being actuated by a jack (no represents) embedded on the movable jaw 60.
- a jack no represents embedded on the movable jaw 60.
- the sealing means 85 is secured, by any suitable means, for example by screwing with the jaws 60,
- the non-rectilinear cutting blade 53 being embedded within the sealing means 65 of in order to be able to substantially simultaneously perform the welding and cutting operation in masked time.
- the same type of integrated assembly can obviously be achieved with rectified cutting blades 55 which are also integrated with the welding means used to simultaneously perform the welding of the rectilinear cut.
- the invention thus not only allows to obtain bags of food whose position is easily spotted visually by the user to be introduced in a preferred position in the cooking liquid and are readily martipulabies without risk of burns while allowing particularly efficient and economical bag manufacture by minimizing the losses of plastic material during cutting. It also turns out that the bag obtained is particularly resistant, particularly at the level of the welds.
- the invention finds its industrial application in the design, implementation and manufacture of food bags, in particular cooking bags.
